Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Considering that the outdoor fan of the air conditioning system mainly achieves the aim of exchanging heat for the outdoor heat exchanger of the air conditioning system through air flow. The outdoor unit of the air conditioning system is provided with a pressure sensor, and the frequency of the outdoor fan can be adjusted by detecting the pressure of the unit through the pressure sensor, so that the heat exchange effect is controlled. The mode of adjusting the frequency of the outdoor fan according to the pressure of the unit is a relatively rough control mode, and cannot accurately reflect the actual heat exchange effect. The maximum frequency of the outdoor fan is formulated according to the maximum requirement of the unit under severe working conditions, so that the output of the outdoor fan can meet all working conditions, therefore, the frequency range of the outdoor fan is wider, the maximum working frequency is different according to the different cooling capacity of the outdoor unit, and the maximum working frequency is generally about 40 Hz. All, according to the mode of unit pressure regulation outdoor fan frequency, often lead to outdoor fan output to be greater than actual demand's heat exchange volume, the increase of outdoor fan frequency can bring certain noise, influences user experience.
According to an embodiment of the present invention, there is provided a control method of an air conditioning system, as shown in fig. 1, which is a schematic flow chart of an embodiment of the method of the present invention. The air conditioning system includes: an outdoor unit and an indoor unit; the outdoor unit includes: an outdoor fan. The number of the indoor units is more than one. And the indoor units participating in the operation of the air conditioning system in the current operation mode are recorded as operation indoor units. The control method of the air conditioning system comprises the following steps: step S110 to step S150.
At step S110, a current outdoor ambient temperature of the air conditioning system is acquired in a current operation mode of the air conditioning system. The current operation mode of the air conditioning system may be an operation mode of any one of functions of the air conditioning system, such as a cooling mode, a heating mode, and the like.
At step S120, a current maximum operation parameter of the outdoor fan in the current operation mode is determined according to the current outdoor environment temperature in the current operation mode, and is recorded as a reference operation parameter. The current maximum operation parameter and the operation parameter in the reference operation parameter of the outdoor fan can be parameters such as output frequency and output rotating speed of the outdoor fan. For example: determining maximum output frequency F of outdoor fan capable of operating in refrigeration mode Maximum value Is the maximum frequency value XHz.
In some embodiments, in step S120, a current maximum operation parameter of the outdoor fan in the current operation mode is determined according to the current outdoor environment temperature in the current operation mode, and the current maximum operation parameter is recorded as a reference operation parameter, including any one of the following determination cases.
Fig. 3 is a flowchart illustrating an embodiment of a method for controlling an outdoor fan frequency of an air conditioning system according to the present invention. As shown in fig. 3, the method for controlling the frequency of an outdoor fan of an air conditioning system provided by the present invention, specifically, a method for dynamically adjusting the maximum output frequency of the outdoor fan, includes:
step 1, determining the maximum output frequency F of an outdoor fan according to the outdoor environment temperature Maximum value Step 2 may then be performed. Taking a refrigeration mode as an example, determining the maximum output frequency F of an outdoor fan according to the outdoor environment temperature Maximum value Specifically, the following cases may be included.
The first case of outdoor ambient temperature based determination: and if the current outdoor environment temperature in the current operation mode is smaller than or equal to the first temperature threshold in the current operation mode, determining the current maximum operation parameter in the current operation mode as a first set operation parameter. The first temperature threshold may be a first set temperature t1.
For example: referring to the example shown in fig. 3, in step 1, the first case: when the outdoor environment temperature T is detected to be less than or equal to the first set temperature T1, the maximum output frequency F of the outdoor fan is allowed Maximum value The frequency X1Hz is first set.
The second outdoor ambient temperature-based determination scenario: and if the current outdoor environment temperature in the current operation mode is greater than the second temperature threshold in the current operation mode, determining the current maximum operation parameter in the current operation mode as a second set operation parameter. The first temperature threshold value in the current operation mode is different from the second temperature threshold value in the current operation mode, namely the second temperature threshold value in the current operation mode is different from the first temperature threshold value in the current operation mode. The second temperature threshold may be a second set temperature t2.
For example: referring to the example shown in fig. 3, in step 1, the second case: when the outdoor environment temperature T is detected to be more than the second set temperature T2, the maximum output frequency F of the outdoor fan is allowed Maximum value The frequency X2Hz is set for the second.
Third determination based on outdoor ambient temperature: and if the current outdoor environment temperature in the current operation mode is greater than the first temperature threshold in the current operation mode and is less than or equal to the second temperature threshold in the current operation mode, determining the current maximum operation parameter in the current operation mode, and maintaining the current maximum operation parameter in the current operation mode determined in the last time.
For example: referring to the example shown in FIG. 3, in step 1, in the third case, when the first set temperature T1 < the outdoor ambient temperature T.ltoreq.second set temperature T2 is detected, the maximum output frequency F of the outdoor fan is allowed Maximum value Unchanged, i.e. maximum output frequency F of outdoor fan Maximum value The maximum frequency value of the previous interval is maintained. For example: if the previous interval is that the outdoor environment temperature T is less than or equal to the first set temperature T1, the maximum output frequency F of the outdoor fan is smaller than the first set temperature T1 and less than or equal to the second set temperature T2 Maximum value The first set frequency X1Hz is maintained. If the previous interval is that the outdoor environment temperature T is greater than the second set temperature T2, the maximum output frequency F of the outdoor fan is smaller than the first set temperature T1 and smaller than or equal to the second set temperature T2 Maximum value The second set frequency X2Hz is maintained.
In the cooling mode, the first set temperature t1 is less than the second set temperature t2, and the first set frequency X1 is less than the second set frequency X2. In the heating mode, the first set temperature t1 is less than the second set temperature t2, and the first set frequency X1 is more than the second set frequency X2.
Assume that the maximum output frequency F of the outdoor fan is finally obtained according to the outdoor environment temperature Maximum value A maximum frequency value XHz, the maximum frequency value XHz is at the first set frequencyThe rate X1Hz or the second set frequency X2 Hz.
For example: in the cooling mode, the first set temperature t1 is 37 degrees (e.g., 37 degrees C.) and the second set temperature t2 is 39 degrees. In general, the second set temperature t2=the first set temperature t1+ sets the temperature threshold Δt. The temperature threshold Deltat is set to be about 2-3 degrees, so that a buffer interval is reserved, and the fluctuation of the output frequency of the outdoor fan caused by the fluctuation of the outdoor environment temperature T is prevented when the outdoor fan just works at the critical point.
The buffer interval is reserved, so that the fluctuation of the output frequency of the fan is prevented, and the situation that the actual running frequency of the fan is already running to the maximum frequency is mainly treated. Such as: if the buffer interval is not provided, the outdoor environment temperature T is less than or equal to 38 ℃, and the maximum output of the fan is 40 ℃; the outdoor environment temperature T is greater than 38 degrees, and the maximum frequency of the fan is 44Hz. Then when the outer ring fluctuates up and down at 38 degrees/39 degrees (temperature sensor sampling, temperature fluctuation is a normal phenomenon), since the blower has already been operated to the maximum frequency 44Hz, the blower maximum frequency will immediately change from 44Hz to 40Hz when the outdoor ambient temperature T fluctuates to 38 degrees.
The first set frequency X1 may take the value of 37Hz and the second set frequency X2 may take the value of 44Hz. The values of the first set frequency X1 and the second set frequency X2 are related to the outdoor environment temperature T, the unit cooling capacity and the number of outdoor fans. The maximum operating frequency of a unit fan with large cooling capacity is larger than that of a unit with small cooling capacity; the unit with the same cold energy has a single fan unit with a larger maximum operable frequency than a double fan unit; when the outdoor environment temperature T is high during refrigeration, the maximum frequency of the fan is higher than that when the outdoor environment temperature T is low. Specific values are generally determined in conjunction with testing.
In the heating mode, the first set temperature t1 is 2-3 degrees, and the second set temperature t2 is 4-5 degrees. The first set frequency X1 may take a value of 40Hz and the second set frequency X2 may take a value of 35Hz. For example: in a heating mode, when the outdoor environment temperature T is less than or equal to 3 ℃, the maximum value of the first set frequency X1 is 38Hz; when the outdoor environment temperature T is greater than 5 degrees, the maximum value of the first set frequency X1 is 35Hz. And if the time is in the rest mode time period, subtracting the delta regulation on the basis of the value. Similarly, in the capacity adjustment mode, the capacity of the indoor unit is operated at less than X kwh, if the outdoor environment temperature T is less than or equal to 3 degrees, the value Y1 is taken, and if the outdoor environment temperature T is greater than 5 degrees, the value Y2 is taken, and if Y1 is greater than Y2, the specific numerical value is generally determined according to experiments.
At step S130, it is determined whether at least one of a rest mode of the air conditioning system and a capacity adjustment mode of the air conditioning system is turned on. The rest mode is a mode for determining the actual maximum operation parameter of the outdoor fan by combining a preset rest period. The rest period can be one period or a plurality of periods, wherein any period can be set by default of the system or flexibly adjusted by a user according to own requirements. The capacity adjustment mode is a mode for determining an actual maximum operation parameter of the outdoor fan in combination with the capacity of the indoor unit. Of course, the current time of the air conditioning system needs to be obtained in the rest mode, and the capacity (such as the rated capacity) of the running indoor unit of the air conditioning system needs to be obtained in the capacity adjustment mode.
At step S140, according to the determination result of whether at least one of the rest mode of the air conditioning system and the capacity adjustment mode of the air conditioning system is on, the final maximum operation parameter of the outdoor unit in the current operation mode is determined as the actual maximum operation parameter of the outdoor unit in the current operation mode in combination with the reference operation parameter or in combination with the current outdoor environment temperature in the current operation mode.
At step S150, the outdoor fan is controlled to operate according to the actual maximum operation parameter in the current operation mode.
According to the scheme, the intelligent frequency adjusting method for the outdoor fan of the air conditioning system is provided, the maximum frequency of the operable outdoor fan is dynamically adjusted according to the outdoor environment temperature, the rated capacity of the indoor unit to be operated and the current system time, the operating frequency of the outdoor fan is properly reduced on the premise of guaranteeing the reliability of a unit, energy conservation and noise reduction are achieved, and the comfort experience of high-demand users is improved.
The scheme of the invention is applied to the multi-split air conditioner, and the multi-split air conditioner generally consists of at least one outdoor unit and at least one indoor unit. The number of indoor units of the common household multi-split air conditioner is 2-8, and the indoor units are selected according to the requirements of users. In view of the capacity requirements of only the indoor units that are in operation, either cooling or heating is required. And the indoor units which are shut down, failed and shut down to the temperature point are not involved in judgment. Therefore, in the scheme of the invention, the maximum frequency at which the outdoor fan can operate is determined by combining the capacity of the indoor unit in operation in the air conditioning system.
As an exemplary illustration, assume that for an outdoor unit having a capacity R of YkW, the maximum output frequency F at which the outdoor fan can operate Maximum value At a maximum frequency value XHz, a minimum output frequency F Minimum of Is the minimum frequency value MHz. Generally, the outdoor fan is adjusted to operate between a minimum frequency value MHz-a maximum frequency value XHz by detecting the difference between the current target pressure and the actual pressure of the unit. According to the scheme, the maximum frequency value XHz of the outdoor fan is intelligently regulated and controlled by detecting the current outdoor environment temperature, the rated capacity of the indoor unit in operation and whether the current system time is a night period or a noon break period in real time.
Such as: outdoor unit with capacity of 18kW and maximum output frequency F of outdoor fan in refrigeration mode Maximum value At a minimum output frequency F of 44Hz Minimum of Is 5Hz.
The above parameters are example parameters, and the actual parameters can be different according to the cooling capacity of the unit, the number of outdoor fans, the running condition of the unit, and the like.
In some embodiments, determining whether at least one of the rest mode of the air conditioning system and the capacity adjustment mode of the air conditioning system is on in step S130 includes: determining whether a rest mode of the air conditioning system is on. And the determined result of whether the rest mode of the air conditioning system is started is that the rest mode is started or the rest mode is not started.
As shown in fig. 3, the method for controlling the frequency of an outdoor fan of an air conditioning system provided by the present invention, specifically, a method for dynamically adjusting the maximum output frequency of the outdoor fan, further includes:
step 2, judging whether a rest mode is started or not: if yes, executing the step 3. Otherwise, step 4 is performed.
The rest mode, namely the time adjustment mode, is a mode customized according to the functions of the unit, and is used for limiting the maximum frequency of the outdoor fan to reduce noise and improve user experience in a period of time when a user is likely to rest. Such as night time 22:30-7:00, noon break time 12:30-13:30, and other times that are user-defined.
Accordingly, in step S140, according to the determination result of whether at least one of the rest mode of the air conditioning system and the capacity adjustment mode of the air conditioning system is on, the final maximum operation parameter of the outdoor unit in the current operation mode is determined in combination with the reference operation parameter or in combination with the current outdoor environment temperature in the current operation mode, including any one of the following determination situations based on the rest mode.
The first case of determination based on resting mode: if the rest mode is started, determining a difference value between the reference operation parameter determined by the current outdoor environment temperature in the current operation mode and a set parameter threshold value as a final maximum operation parameter of the outdoor unit in the current operation mode under the condition that the current time of the air conditioning system is in a rest period preset in the rest mode.
The second rest mode-based determination scenario: if the rest mode is started, under the condition that the current time of the air conditioning system is not in a rest period preset in the rest mode, determining the reference operation parameter determined by the current outdoor environment temperature in the current operation mode as the final maximum operation parameter of the outdoor unit in the current operation mode.
As shown in fig. 3, the method for controlling the frequency of an outdoor fan of an air conditioning system provided by the present invention, specifically, a method for dynamically adjusting the maximum output frequency of the outdoor fan, further includes:
step 3, atUnder the condition that the rest mode is started, determining the maximum output frequency F of the outdoor fan according to the rest mode Maximum value A frequency threshold delta XHz is set for the first frequency value x3hz=maximum frequency value XHz-, after which step 5 may be performed.
The outdoor unit of the air conditioning system is generally configured with a GPRS (general packet radio service) module, and the GPRS module can acquire accurate system time from a server end and time service to an air conditioning system unit. When the outdoor unit of the air conditioning system receives the GPRS time service, if the outdoor unit is judged to be in the period of the first set time H1-the second set time H2 which is the night time or the period of the third set time H3-the fourth set time H4 which is the noon break time, the maximum frequency of the outdoor fan is reduced by the set frequency threshold delta XHz on the basis of determining the maximum frequency value XHz of the outdoor fan according to the outdoor environment temperature.
The scheme of the invention can be provided with a plurality of rest modes, wherein the rest modes are selectable, for example, a user can freely select N rest modes, different time periods and outdoor fan frequency adjustment values are selected, and N is a positive integer.
Optionally, the scheme of the invention can also open time period setting to the user. If there is no optional time period in the existing N rest modes, the user can enter a rest mode setting mode, and set the beginning and ending time of the night period and the noon break period of any one of the rest modes according to own requirements.
Under the condition of combining the outdoor environment temperature and whether the rest mode is started, the maximum output frequency F of the outdoor fan is obtained Maximum value Is the first frequency value X3Hz.
The first frequency value X3Hz is less than the first set frequency X1Hz, the first frequency value X3Hz is less than the second set frequency X2Hz, the first frequency value X3 hz=the maximum frequency value XHz-the set frequency threshold delta XHz, the maximum frequency value XHz is the maximum output frequency of the outdoor fan finally obtained according to the outdoor environment temperature THz, and the maximum frequency value XHz takes a value in the first set frequency X1Hz or the second set frequency X2 Hz. The frequency threshold Delta XHz is set and can be different according to the mode selected by the user, and is generally 3-8Hz.
For example: the different modes selected by the user mainly means that a plurality of preset schemes can be selected for the user, and in which time period, the maximum frequency of the fan can be slightly adjusted to be smaller, and the delta X is adjusted downwards. Such as night time 22:30-7:00, noon break time 12:30-13:30, and user-defined times. DeltaX may be 3hz/5hz/8hz, etc. to reduce noise appropriately. Of course, the range of Δx values should not be too large, preventing the comfort from being compromised.
Third determination scenario based on rest mode: and if the rest mode is not started, determining the reference operating parameter determined by the current outdoor environment temperature in the current operating mode as the final maximum operating parameter of the outdoor unit in the current operating mode.
As shown in fig. 3, the method for controlling the frequency of an outdoor fan of an air conditioning system provided by the present invention, specifically, a method for dynamically adjusting the maximum output frequency of the outdoor fan, further includes:
step 4, under the condition that the rest mode is not started, determining the maximum output frequency F of the outdoor fan Maximum value For the first frequency value x3hz=maximum frequency value XHz, step 5 may be performed thereafter.
In some embodiments, determining in step S130 whether at least one of the rest mode of the air conditioning system and the capacity adjustment mode of the air conditioning system is on further includes: determining whether a capacity adjustment mode of the air conditioning system is on. And the determined result of whether the capacity adjustment mode of the air conditioning system is started is that the capacity adjustment mode is started or that the capacity adjustment mode is not started.
As shown in fig. 3, the method for controlling the frequency of an outdoor fan of an air conditioning system provided by the present invention, specifically, a method for dynamically adjusting the maximum output frequency of the outdoor fan, further includes:
step 5, judging whether the capacity adjustment mode is started or not: if yes, go to step 6. Otherwise, step 7 is performed.
And the capacity adjustment mode is a mode for adjusting the maximum output frequency of the outdoor fan according to the running state of the indoor unit.
Accordingly, in step S140, according to the determination result of whether at least one of the rest mode of the air conditioning system and the capacity adjustment mode of the air conditioning system is on, the final maximum operation parameter of the outdoor unit in the current operation mode is determined in combination with the reference operation parameter or in combination with the current outdoor environment temperature in the current operation mode, and any one of the following determination situations based on the capacity adjustment mode is further included:
the first capacity adjustment mode-based determination scenario: if the capacity adjustment mode is started, determining an allowable maximum operation parameter of the area under the condition that the outdoor environment temperature under the current operation mode is less than or equal to the first set temperature under the current operation mode according to the area of the capacity of the indoor unit in the set capacity interval, wherein the area is the final maximum operation parameter of the outdoor unit under the current operation mode.
As shown in fig. 3, the method for controlling the frequency of an outdoor fan of an air conditioning system provided by the present invention, specifically, a method for dynamically adjusting the maximum output frequency of the outdoor fan, further includes:
step 6, under the condition that the capacity adjustment mode is started, determining the maximum output frequency F of the outdoor fan according to the outdoor environment temperature and the running capacity of the indoor unit Maximum value At a second frequency value ZHz, step 8 may then be performed.
In the use case of the multi-split air conditioner, generally, one outdoor unit is matched with a plurality of indoor units, and any indoor unit can be freely set to be switched by a user. In addition, when the same indoor unit is started, the operation of the indoor unit may be stopped because the indoor environment temperature has reached the temperature requirement set by the user. Therefore, the indoor unit is not fixed in the on state, and the frequency requirement of the outdoor fan is different. In the scheme of the invention, the outdoor unit detects whether the indoor unit operates in real time, and dynamically adjusts the maximum operating frequency of the outdoor fan according to the rated capacity R of the indoor unit:
when the outdoor environment temperature T is less than or equal to the first set temperature T1:
and if the rated capacity R of the indoor unit is less than or equal to the first set capacity R1, allowing the maximum output frequency of the outdoor fan to be the first corresponding frequency Z11.
And if the first set capacity R1 is smaller than the rated capacity R of the indoor unit and is smaller than or equal to the second set capacity R2, the maximum output frequency of the outdoor fan is allowed to be the second corresponding frequency Z12.
And if the second set capacity R2 is smaller than the rated capacity R of the indoor unit and is smaller than or equal to the third set capacity R3, the maximum output frequency of the outdoor fan is allowed to be the third corresponding frequency Z13.
And if the third set capacity R3 is smaller than the rated capacity R of the indoor unit and is smaller than or equal to the fourth set capacity R4, the maximum output frequency of the outdoor fan is allowed to be the fourth corresponding frequency Z14.
And if the fourth set capacity R4 is smaller than the rated capacity R of the indoor unit and is smaller than or equal to the fifth set capacity R5, the maximum output frequency of the outdoor fan is allowed to be the fifth corresponding frequency Z15.
And if the rated capacity R of the indoor unit is larger than the fifth set capacity R5, the maximum output of the outdoor fan is allowed to be the sixth corresponding frequency Z16.
Wherein: the first set capacity r1 is more than second set capacity r2 is more than third set capacity r3 is more than fourth set capacity r4 is less than fifth set capacity r5, the first corresponding frequency Z11 is more than or equal to the second corresponding frequency Z12 is more than or equal to the third corresponding frequency Z13 is more than or equal to the fourth corresponding frequency Z14 is more than or equal to the fifth corresponding frequency Z15 is more than or equal to the sixth corresponding frequency Z16.
The second capacity adjustment mode-based determination scenario: if the capacity adjustment mode is started, determining a maximum allowable operation parameter of the area under the condition that the outdoor environment temperature under the current operation mode is greater than the second set temperature under the current operation mode according to the area of the capacity of the indoor unit in the set capacity interval, wherein the area is the final maximum operation parameter of the outdoor unit under the current operation mode.
As shown in fig. 3, the method for controlling the frequency of an outdoor fan of an air conditioning system provided by the present invention, specifically, a method for dynamically adjusting the maximum output frequency of the outdoor fan, further includes: in step 6, similarly, when the outdoor ambient temperature T > the second set temperature T2 is detected:
and if the rated capacity R of the indoor unit is less than or equal to the first set capacity R1, allowing the maximum output frequency of the outdoor fan to be a seventh corresponding frequency Z21.
And if the first set capacity R1 is smaller than the rated capacity R of the indoor unit and is smaller than or equal to the second set capacity R2, the maximum output frequency of the outdoor fan is allowed to be the eighth corresponding frequency Z22.
And if the second set capacity R2 is smaller than the rated capacity R of the indoor unit and is smaller than or equal to the third set capacity R3, allowing the maximum output frequency of the outdoor fan to be the ninth corresponding frequency Z23.
And if the third set capacity R3 is smaller than the rated capacity R of the indoor unit and is smaller than or equal to the fourth set capacity R4, the maximum output frequency of the outdoor fan is allowed to be the tenth corresponding frequency Z24.
And if the fourth set capacity R4 is smaller than the rated capacity R of the indoor unit and is smaller than or equal to the fifth set capacity R5, allowing the maximum output frequency of the outdoor fan to be the eleventh corresponding frequency Z25.
If the rated capacity R of the indoor unit is larger than the fifth set capacity R5, the maximum output of the outdoor fan is allowed to be the twelfth corresponding frequency Z26.
Wherein: the first set capacity r1 is more than second set capacity r2 is more than third set capacity r3 is more than fourth set capacity r4 is less than fifth set capacity r5, the seventh corresponding frequency Z21 is more than or equal to eighth corresponding frequency Z22 is more than or equal to ninth corresponding frequency Z23 is more than or equal to tenth corresponding frequency Z24 is more than or equal to eleventh corresponding frequency Z25 is more than or equal to twelfth corresponding frequency Z26.
In the scheme, the capacity of the indoor unit in operation is divided into different ranges, and when the sum of the capacities of the indoor units in operation is smaller, the maximum output frequency of the allowed outdoor fan is relatively smaller, and otherwise, the maximum output frequency of the outdoor fan is increased. Such as: the first set capacity r1 can take on 5kW, the second set capacity r2 can take on 8kW, the third set capacity r3 can take on 10kW, the fourth set capacity r4 can take on 11.2kW, and the fifth set capacity r5 can take on 14kW. Can also continue to take the capacities of 16kW, 18kW, 20kW and the like asThe segmentation is adjustable according to the configuration of the indoor unit and the capacity of the outdoor unit. Maximum output frequency F of outdoor fan Maximum value And the adjustment is generally carried out between 30 and 50Hz, and the adjustment is required to be determined according to the division of capacity segments of the indoor unit, the size of the outer ring, the cooling capacity of the outdoor unit and the like and the experimental conditions.
For example: the larger the capacity of the indoor unit is, the larger the maximum operating frequency of the fan is. In general, the ratio between the capacity of the multi-connected external machine and the capacity of the internal machine is required, and the super-matching is not allowed, because the super-matching of the internal machine can influence the refrigerating and heating effects of the unit. For example, an 8kW external machine, the sum of the internal machine capacities will generally not exceed 12kW (the total internal machine capacity is approximately between 0.5 and 1.4 times the external machine capacity). When dividing the interval according to the capacity of the internal machine, the large capacity interval can not be divided (the division is not relevant, and the actual machine set cannot be executed); for an external machine of 40kW, the internal machine capacity division naturally takes into account the larger interval. Because specific values are written, it is necessary to state that the values are not fixed, and are related to the capacity of the unit. The capacity interval can be divided according to actual demands, for example, more intervals can be divided, and less intervals can be also obtained.
Third determination scenario based on capacity adjustment mode: if the capacity adjustment mode is not started, determining a final maximum operation parameter of the outdoor unit in the current operation mode according to a determination result of whether the rest mode of the air conditioning system is started or not and combining the reference operation parameter.
As shown in fig. 3, the method for controlling the frequency of an outdoor fan of an air conditioning system provided by the present invention, specifically, a method for dynamically adjusting the maximum output frequency of the outdoor fan, further includes: step 7, under the condition that the capacity adjustment mode is not started, determining the maximum output frequency F of the outdoor fan Maximum value For the final frequency value x0hz=first frequency value X3Hz.
In some embodiments, determining in step S130 whether at least one of the rest mode of the air conditioning system and the capacity adjustment mode of the air conditioning system is on further includes: determining whether a rest mode of the air conditioning system and a capacity adjustment mode of the air conditioning system are on. The determination result of whether the rest mode of the air conditioning system and the capacity adjustment mode of the air conditioning system are started is: the rest mode of the air conditioning system and the capacity adjustment mode of the air conditioning system are both started, or the rest mode of the air conditioning system is started, and the capacity adjustment mode of the air conditioning system is not started, or the rest mode of the air conditioning system is not started, and the capacity adjustment mode of the air conditioning system is started, or the rest mode of the air conditioning system and the capacity adjustment mode of the air conditioning system are both not started.
Accordingly, in step S140, according to the determination result of whether at least one of the rest mode of the air conditioning system and the capacity adjustment mode of the air conditioning system is on, the final maximum operation parameter of the outdoor unit in the current operation mode is determined in combination with the reference operation parameter or in combination with the current outdoor environment temperature in the current operation mode, and any one of the following comprehensive determination situations are further included:
first comprehensive determination scenario: if the rest mode of the air conditioning system and the capacity adjustment mode of the air conditioning system are both started, selecting the final maximum operation parameter of the outdoor fan in the current operation mode, wherein the final maximum operation parameter of the outdoor unit in the current operation mode is determined under the condition that the rest mode is started, and the smaller one of the final maximum operation parameter of the outdoor unit in the current operation mode is determined under the condition that the capacity adjustment mode is started.
As shown in fig. 3, the method for controlling the frequency of an outdoor fan of an air conditioning system provided by the present invention, specifically, a method for dynamically adjusting the maximum output frequency of the outdoor fan, further includes: step 8, under the condition that the capacity adjustment mode is started, determining the maximum output frequency F of the outdoor fan Maximum value The smaller of the first frequency value X3Hz and the second frequency value ZHz is taken as the final frequency value X0 Hz.
Second comprehensive determination scenario: if the rest mode of the air conditioning system is started and the capacity adjustment mode of the air conditioning system is not started, the final maximum operation parameter of the outdoor fan in the current operation mode is selected, and the final maximum operation parameter of the outdoor unit in the current operation mode is determined under the condition that the rest mode is started.
Third comprehensive determination scenario: and if the rest mode of the air conditioning system is not started and the capacity adjustment mode of the air conditioning system is started, selecting the final maximum operation parameter of the outdoor fan in the current operation mode, wherein the final maximum operation parameter of the outdoor unit in the current operation mode is determined under the condition that the capacity adjustment mode is started.
Fourth comprehensive determination scenario: and if the rest mode of the air conditioning system and the capacity adjustment mode of the air conditioning system are not started, selecting the final maximum operation parameter of the outdoor fan in the current operation mode according to the outdoor environment temperature in the current operation mode.
Finally, maximum output frequency F of the allowable outdoor fan Maximum value The final frequency value X0Hz may be a second frequency value ZHz of the outdoor wind determined according to the capacity R of the operating indoor unit in the capacity adjustment mode. The second frequency value ZHz of the outdoor wind is one of the first to sixth corresponding frequencies Z11 to Z16, and the seventh to twelfth corresponding frequencies Z21 to Z26, which are determined according to the outdoor ambient temperature T and the capacity R of the operating indoor unit. The maximum frequency value X0Hz of the allowable outdoor fan may be determined according to the outdoor ambient temperature T and the first frequency value X3Hz determined by the rest mode. If the second frequency value ZHz is smaller than the first frequency value X3Hz, the first frequency value X3Hz is selected, that is, the final frequency value x0hz=the first frequency value X3Hz of the outdoor fan. Otherwise, selecting a second frequency value ZHz, and obtaining a final frequency value x0hz=a second frequency value ZHz by the outdoor fan.
Optionally, the user may also choose whether to enable the maximum output frequency F of the outdoor fan determined from the rest mode Maximum value Determining maximum output frequency F of outdoor fan according to capacity adjustment mode Maximum value Etc. If the rest mode is not started, the final outdoor windMaximum output frequency F of machine Maximum value The smaller of the maximum frequency value XHz determined from the outdoor ambient temperature and the second frequency value ZHz determined from the capacity of the operating indoor unit. If the capacity adjustment mode is not started, the maximum output frequency F of the outdoor fan is finally obtained Maximum value Is a first frequency value X3Hz determined according to the outdoor environment temperature and the capacity of the operating indoor unit. If the rest mode and the capacity adjustment mode are not started, the maximum output frequency F of the outdoor fan Maximum value Is a maximum frequency value XHz determined from the outdoor ambient temperature.
According to the scheme of the invention, the maximum frequency of the outdoor fan which can be operated is dynamically adjusted according to the outdoor environment temperature, the rated capacity of the indoor unit which is operated and whether the current system time is in a night period or a noon break period, so that the purposes of energy conservation and noise reduction are achieved.
By adopting the technical scheme of the embodiment, the maximum frequency at which the outdoor fan can operate is dynamically adjusted according to the outdoor environment temperature, the rated capacity of the indoor unit and the current system time by acquiring the outdoor environment temperature of the air conditioning system, the rated capacity of the indoor unit operated in more than one indoor unit and the current system time. Therefore, the maximum frequency of the outdoor fan capable of running is dynamically adjusted, so that the running frequency of the outdoor fan is properly reduced on the premise of ensuring the reliability of the unit, and energy conservation and noise reduction are further realized.
According to an embodiment of the present invention, there is also provided a control apparatus of an air conditioning system corresponding to the control method of the air conditioning system. Referring to fig. 2, a schematic diagram of an embodiment of the apparatus of the present invention is shown. The air conditioning system includes: an outdoor unit and an indoor unit. The outdoor unit includes: an outdoor fan. The number of the indoor units is more than one. And the indoor units participating in the operation of the air conditioning system in the current operation mode are recorded as operation indoor units. The control device of the air conditioning system comprises: an acquisition unit 102 and a control unit 104.
Wherein the obtaining unit 102 is configured to obtain a current outdoor environment temperature of the air conditioning system in a current operation mode of the air conditioning system. The specific function and process of the acquisition unit 102 refer to step S110. The current operation mode of the air conditioning system may be an operation mode of any one of functions of the air conditioning system, such as a cooling mode, a heating mode, and the like.
And the control unit 104 is configured to determine a current maximum operation parameter of the outdoor fan in the current operation mode according to the current outdoor environment temperature in the current operation mode, and record the current maximum operation parameter as a reference operation parameter. The specific function and process of the control unit 104 refer to step S120. The current maximum operation parameter and the operation parameter in the reference operation parameter of the outdoor fan can be parameters such as output frequency and output rotating speed of the outdoor fan. For example: determining maximum output frequency F of outdoor fan capable of operating in refrigeration mode Maximum value Is the maximum frequency value XHz.
In some embodiments, the control unit 104 determines a current maximum operating parameter of the outdoor fan in the current operating mode according to the current outdoor environment temperature in the current operating mode, and marks the current maximum operating parameter as a reference operating parameter, including any one of the following determination cases.
Fig. 3 is a schematic flow chart of an embodiment of an outdoor fan frequency control device of an air conditioning system according to the present invention. As shown in fig. 3, the frequency control device for an outdoor fan of an air conditioning system provided by the present invention, specifically, a device for dynamically adjusting the maximum output frequency of the outdoor fan, includes:
step 1, determining the maximum output frequency F of an outdoor fan according to the outdoor environment temperature Maximum value Step 2 may then be performed. Taking a refrigeration mode as an example, determining the maximum output frequency F of an outdoor fan according to the outdoor environment temperature Maximum value Specifically, the following cases may be included.
The first case of outdoor ambient temperature based determination: the control unit 104 is specifically further configured to determine that the current maximum operation parameter in the current operation mode is the first set operation parameter if the current outdoor environment temperature in the current operation mode is less than or equal to the first temperature threshold in the current operation mode. The first temperature threshold may be a first set temperature t1.
For example: referring to the example shown in fig. 3, in step 1, the first case: when the outdoor environment temperature T is detected to be less than or equal to the first set temperature T1, the maximum output frequency F of the outdoor fan is allowed Maximum value The frequency X1Hz is first set.
The second outdoor ambient temperature-based determination scenario: the control unit 104 is specifically further configured to determine that the current maximum operating parameter in the current operating mode is a second set operating parameter if the current outdoor environmental temperature in the current operating mode is greater than the second temperature threshold in the current operating mode. The first temperature threshold value in the current operation mode is different from the second temperature threshold value in the current operation mode, namely the second temperature threshold value in the current operation mode is different from the first temperature threshold value in the current operation mode. The second temperature threshold may be a second set temperature t2.
For example: referring to the example shown in fig. 3, in step 1, the second case: when the outdoor environment temperature T is detected to be more than the second set temperature T2, the maximum output frequency F of the outdoor fan is allowed Maximum value The frequency X2Hz is set for the second.
Third determination based on outdoor ambient temperature: the control unit 104 is specifically further configured to determine a current maximum operating parameter in the current operating mode and maintain the current maximum operating parameter in the current operating mode determined in the previous time if the current outdoor environmental temperature in the current operating mode is greater than the first temperature threshold in the current operating mode and is less than or equal to the second temperature threshold in the current operating mode.
For example: referring to the example shown in FIG. 3, in step 1, in the third case, when the first set temperature T1 < the outdoor ambient temperature T.ltoreq.second set temperature T2 is detected, the maximum output frequency F of the outdoor fan is allowed Maximum value Unchanged, i.e. maximum output frequency F of outdoor fan Maximum value Maintain upA maximum frequency value for a range. For example: if the previous interval is that the outdoor environment temperature T is less than or equal to the first set temperature T1, the maximum output frequency F of the outdoor fan is smaller than the first set temperature T1 and less than or equal to the second set temperature T2 Maximum value The first set frequency X1Hz is maintained. If the previous interval is that the outdoor environment temperature T is greater than the second set temperature T2, the maximum output frequency F of the outdoor fan is smaller than the first set temperature T1 and smaller than or equal to the second set temperature T2 Maximum value The second set frequency X2Hz is maintained.
In the cooling mode, the first set temperature t1 is less than the second set temperature t2, and the first set frequency X1 is less than the second set frequency X2. In the heating mode, the first set temperature t1 is less than the second set temperature t2, and the first set frequency X1 is more than the second set frequency X2.
Assume that the maximum output frequency F of the outdoor fan is finally obtained according to the outdoor environment temperature Maximum value The maximum frequency value XHz is set to be equal to the maximum frequency value XHz in the first set frequency X1Hz or the second set frequency X2Hz.
For example: in the cooling mode, the first set temperature t1 is 37 degrees (e.g., 37 degrees C.) and the second set temperature t2 is 39 degrees. In general, the second set temperature t2=the first set temperature t1+ sets the temperature threshold Δt. The temperature threshold Deltat is set to be about 2-3 degrees, so that a buffer interval is reserved, and the fluctuation of the output frequency of the outdoor fan caused by the fluctuation of the outdoor environment temperature T is prevented when the outdoor fan just works at the critical point.
