Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
For the convenience of understanding the solution provided by the present invention, the cooling principle and the heating principle of the air conditioner will be explained first.
The refrigeration principle of the air conditioner is as follows: when the air conditioner works, low-pressure and low-temperature refrigerant vapor in the refrigerating system is sucked by the compressor, compressed into high-pressure and high-temperature superheated vapor by the compressor and then discharged to the condenser; meanwhile, outdoor air sucked by the outdoor fan flows through the condenser to take away heat emitted by the refrigerant, so that high-pressure and high-temperature refrigerant steam is condensed into high-pressure liquid. High-pressure liquid flows into the indoor heat exchanger through throttling capillary tubes, reducing pressure and temperature, is evaporated under corresponding low pressure, and absorbs ambient heat; meanwhile, the indoor fan enables indoor air to continuously enter fins of the indoor side heat exchanger for heat exchange, and sends the cooled air after heat release to the indoor. Thus, the indoor air continuously circulates and flows to achieve the purpose of reducing the temperature.
The heating principle of the air conditioner is as follows: the low-pressure and low-temperature refrigerant liquid is sucked by the compressor and then is changed into high-temperature and high-pressure superheated steam, and the high-temperature and high-pressure superheated steam is condensed in the indoor side heat exchanger and releases heat to be changed into medium-temperature and high-pressure liquid. Indoor air is heated through indoor heat exchange on the surface of the indoor side heat exchanger, and the heated air is blown out through the indoor fan, so that the heating purpose is achieved, medium-temperature high-pressure liquid is changed into low-temperature low-pressure liquid after being throttled, decompressed and cooled through the throttle capillary tube, the low-temperature low-pressure liquid enters the outdoor heat exchanger, meanwhile, outdoor air sucked by the outdoor fan is absorbed when passing through the outdoor heat exchanger, so that the low-temperature low-pressure liquid in the outdoor heat exchanger is evaporated into low-temperature low-pressure gas, the low-temperature low-pressure gas is sucked by the compressor again, and the circulation is carried out, so that the heating purpose is achieved.
The prior air conditioner adopts an operation mode that after a compressor operates for a period of time, the refrigeration/heating effect of the air conditioner is judged according to the difference change between the indoor environment temperature and the target temperature set by a user, and then the operation frequency of the compressor is adjusted according to the refrigeration/heating effect so as to achieve the purpose of better refrigeration/heating.
In order to solve the technical problem that the conventional air conditioner cannot perform quick cooling/heating, the embodiment of the invention provides an air conditioner control method.
An air conditioner control method according to an embodiment of the present invention will be described with reference to the accompanying drawings.
Fig. 1 is a flowchart of an air conditioner control method according to an embodiment of the present invention, where the method may be applied to an air conditioner controller to control an air conditioner, and as shown in fig. 1, the method may include the following steps:
and S11, when a starting instruction is received, controlling the outdoor fan and the compressor to operate according to a set first mode.
The starting instruction is an instruction for controlling the air conditioner to start running, and the starting instruction usually carries an operation mode (a cooling mode or a heating mode) and a target temperature set by a user.
After receiving a starting instruction, no matter the operation mode set by a user is a heating mode or a cooling mode, the outdoor fan and the compressor are controlled to operate according to a set first mode.
The set first mode comprises the operation parameters of the outdoor fan and the operation parameters of the compressor, and the control of the outdoor fan and the compressor to operate according to the set first mode is that the control of the outdoor fan and the compressor to operate according to the corresponding operation parameters in the first mode.
As an embodiment, the operating parameter of the outdoor fan included in the first operating mode is a maximum rotation speed of the outdoor fan, and the operating parameter of the compressor is a maximum frequency of the compressor, based on which controlling the outdoor fan and the compressor to operate according to the set first mode includes: controlling the outdoor fan to operate at a maximum rotation speed, and controlling the compressor to operate at a maximum frequency. The maximum rotating speed of the outdoor fan is determined by parameters of the outdoor fan, and the maximum rotating speed of the fan of a certain model is usually fixed, so that the maximum rotating speed of the outdoor fan can be determined according to the model of the outdoor fan used in the air conditioner. The maximum frequency of the compressor is also determined by the parameters of the compressor, and particularly, the maximum frequency of the compressor can also be determined according to the model of the compressor.
And S12, when the temperature of the coil pipe of the indoor side heat exchanger meets the preset requirement, controlling the indoor fan to be started, and controlling the indoor fan to operate according to a set second mode.
According to the description of step S12, when the coil temperature of the indoor heat exchanger does not meet the preset requirement, the indoor fan is not turned on, and the coil temperature of the indoor heat exchanger can reach the preset requirement more quickly by turning on the indoor fan in a delayed manner.
As an example, the coil temperature of the indoor side heat exchanger may be detected by a temperature detection device (e.g., a bulb) disposed near the coil of the indoor side heat exchanger. The coil temperature of the indoor side heat exchanger is collected once every preset time by the specific temperature detection device, and the coil temperature of the indoor side heat exchanger meets the preset requirement until the coil temperature of the indoor side heat exchanger meets the preset requirement, wherein the preset time can be set according to the actual requirement, for example, 1s and the like.
As can be seen from the above description of the heating and cooling principles of the air conditioner, the indoor side heat exchanger of the air conditioner has different functions in the heating mode to heat the indoor temperature by releasing heat, and in the cooling mode to cool the indoor temperature by absorbing heat. Therefore, the coil temperature of the indoor side is different under different operation modes, and the preset requirements corresponding to the coil temperature of the indoor side heat exchanger are different under different operation modes.
As an example, when the operation mode of the air conditioner is the heating mode, the preset requirements may be that the coil temperature of the indoor side heat exchanger is not less than the first temperature threshold value and the duration time is not less than the first time threshold value. Based on this, when the operation mode of the air conditioner is the heating mode, if the coil temperature of the indoor side heat exchanger is not less than the first temperature threshold value and the duration time is not less than the first time threshold value, it is determined that the coil temperature of the indoor side heat exchanger meets the preset requirement. The first temperature threshold and the first time threshold are set according to actual requirements, for example, the first temperature threshold is 54 ℃, the first time threshold is 15s, or the first temperature threshold is 56 ℃, the first time threshold is 10s, or the first temperature threshold is 58 ℃, the first time threshold is 5s, or the first temperature threshold is 60 ℃, the first time threshold is 0.1s, and so on.
Further, the first temperature threshold in the preset condition may be one or multiple, and the first time threshold may also be one or multiple, when the first temperature threshold is multiple, a corresponding relationship between the first temperature threshold and the first time threshold needs to be preset, where the corresponding relationship may be many-to-one, that is, multiple first temperature thresholds correspond to one first time threshold, or one-to-one, that is, each first temperature threshold corresponds to a different first time threshold, specifically set according to actual requirements, and the embodiment of the present invention is not specifically limited.
As an embodiment, when the operation mode of the air conditioner is the cooling mode, the preset requirement is that the coil temperature of the indoor side heat exchanger is not greater than the second temperature threshold value and the duration time is not less than the second time threshold value. Based on this, when the operation mode of the air conditioner is the cooling mode, if the coil temperature of the indoor side heat exchanger is not greater than the second temperature threshold value and the duration time is not less than the second time threshold value, it is determined that the coil temperature of the indoor side heat exchanger meets the preset requirement. The second temperature threshold and the second time threshold are also set according to actual requirements, for example, the second temperature threshold is 10 ℃, the second time threshold is 15s, or the second temperature threshold is 8 ℃, the second time threshold is 10s, or the second temperature threshold is 6 ℃, the second time threshold is 5s, or the second temperature threshold is 4 ℃, the second time threshold is 0.1s, and so on.
Further, the second temperature threshold in the preset condition may be one or multiple, and the second time threshold may be one or multiple, when the second temperature threshold is multiple, a corresponding relationship between the second temperature threshold and the second time threshold needs to be preset, where the corresponding relationship may be many-to-one, that is, multiple second temperature thresholds correspond to one second time threshold, or one-to-one, that is, each second temperature threshold corresponds to one second time threshold, specifically, the setting is according to actual requirements, and the embodiment of the present invention is not particularly limited.
According to the control method of the air conditioner, when the air conditioner receives a starting instruction, the outdoor fan and the compressor are controlled to operate according to a set first mode, when the temperature of the coil of the indoor side heat exchanger meets a preset requirement, the indoor fan is controlled to be started, and the indoor fan is controlled to operate according to a set second mode. In this scheme, when the air conditioner was opened, compressor and outdoor fan were opened earlier to make the coil pipe temperature of indoor side heat exchanger descend/rise, when the coil pipe temperature of indoor side heat exchanger accorded with preset the requirement, opened indoor fan again, opened indoor fan through postponing, made indoor set coil pipe temperature descend/rise rapidly, and then made when opening indoor fan, the coil pipe temperature had enough lowly/high, and then the air-out temperature just also enough lowly/high, thereby realize rapid cooling/intensification.
Fig. 2 is a flowchart of another air conditioner control method according to an embodiment of the present invention, as shown in fig. 2, the method may include the following steps:
and S21, when a starting instruction is received, controlling the outdoor fan and the compressor to operate according to a set first mode.
For details, reference may be made to the description of S11, which is not described herein again.
And S22, adjusting an air deflector and a wind sweeping blade of the indoor unit to a preset most smooth air outlet position.
As an embodiment, the most downwind position is the position where the wind deflector and the wind sweeping blade have the least influence on the wind. The air outlet is not smooth due to the fact that the more wind is kept by the air deflector, the smaller the air volume is, otherwise, the air outlet is smooth, the influence of the air deflector on the air outlet is required to reciprocate between smooth and unsmooth in the rotating process of the air deflector of the air conditioner, and a position with the most smooth air outlet is arranged, so that the most smooth air outlet position of the air conditioner can be determined through multiple air outlet tests during production of the air conditioner, and then relevant position information of the position is stored into a storage device of the air conditioner. Based on this, in step S22, the indoor unit air deflector and the air sweeping blade may be adjusted to the preset most downstream air outlet position according to the position information of the most downstream air outlet position pre-stored in the air conditioner.
And S23, when the temperature of the coil pipe of the indoor side heat exchanger meets the preset requirement, controlling the indoor fan to be started, and controlling the indoor fan to operate according to a set second mode.
For details, reference may be made to the description of S12, which is not described herein again.
In this embodiment, the air guide plate and the air sweeping blade of the indoor unit are adjusted to the most smooth position of the air outlet, so that the air outlet is ensured to be smoother, and the refrigerating/heating effect is stronger.
Fig. 3 is a flowchart of another air conditioner control method according to an embodiment of the present invention, and as shown in fig. 3, the method may include the following steps:
and S31, when a starting instruction is received, controlling the outdoor fan and the compressor to operate according to a set first mode.
For details, reference may be made to the description of S11, and details are not repeated here.
And S32, adjusting an air deflector and a wind sweeping blade of the indoor unit to a preset most smooth air outlet position.
For details, reference may be made to the description of S22, which is not described herein again.
And S33, when the temperature of the coil of the indoor side heat exchanger meets the preset requirement, controlling the indoor fan to be started, and controlling the indoor fan to operate according to a set second mode.
For details, reference may be made to the description of S11, which is not described herein again.
And S34, when the change rate of the indoor environment temperature meets a preset condition, controlling the rotating speed of the indoor fan and the frequency of the compressor to be reduced until the rotating speed of the indoor fan is reduced to a first set rotating speed, and controlling the frequency of the compressor to be reduced to a first set frequency.
The first set rotating speed and the first set frequency are set according to actual requirements.
As an example, as shown in fig. 4, it may be determined whether the rate of change of the indoor ambient temperature meets the preset condition by:
s41, obtaining the indoor environment temperature and the indoor fan operation duration in real time.
As an embodiment, the indoor ambient temperature may be collected by the indoor ambient temperature detection device, the running duration of the indoor fan is determined by the timer, after the indoor fan is started, the timer starts to count time, the indoor ambient temperature detection device starts to collect the indoor ambient temperature according to a preset time interval (set according to actual requirements, for example, 1s), and then the controller of the air conditioner acquires the indoor ambient temperature collected by the indoor ambient temperature detection device and the time recorded by the timer.
And S42, determining the theoretical time required for the indoor environment temperature to reach the set target temperature according to the indoor environment temperature.
As an embodiment, taking the time interval of the temperature collection by the indoor environment temperature detection device as 1S as an example, the indoor environment temperature detection device will collect one indoor environment temperature every 1S, so that multiple indoor environment temperatures are obtained in S41, and a label can be added to the indoor environment temperature according to the time sequence of the indoor environment temperature collection, because the indoor environment temperature detection device and the timer are started simultaneously, the first indoor environment temperature should be collected by the indoor environment temperature detection device when the time recorded by the timer is 0S, and therefore the label of the collected first indoor environment temperature can be recorded as TInner ring 0And acquiring a second indoor environment temperature when the time recorded by the timer is 1s, wherein the acquired label of the second indoor environment temperature can be recorded as TInner ring 1In this way, if the current time recorded by the timer is ns, the label corresponding to the indoor environment temperature acquired at the current time is TInner ring n。
When the air conditioner is in different operation modes, the change rule of the indoor environment temperature is different, so that the mode of determining the theoretical time required for the indoor environment temperature to reach the target temperature is different according to the acquired indoor environment temperature in different operation modes.
As an example, when the operation mode of the air conditioner is the cooling mode, the theoretical time period required for the indoor ambient temperature to reach the target temperature may be calculated using the following formula:
ttheory of the invention＝[(TInner ring 0+A+B+C-TSetting up)/(TInner ring n-TInner ring n-m)]*m
Wherein, tTheory of the inventionIndicates the theoretical time length, T, required for the indoor ambient temperature to reach the set temperatureInner ring 0Indicating the first acquired indoor ambient temperature, A, B, C is the set temperature compensation value, TSetting upIndicating the set temperature, TInner ring nThe indoor environment temperature obtained at the current moment is represented, m is a positive integer not less than 1 preset according to actual requirements, and for example, m can be 6.
As an example, when the current operation mode of the air conditioner is the heating mode, the theoretical time period required for the indoor ambient temperature to reach the target temperature may be calculated by using the following formula:
ttheory of the invention＝[(TSetting up-TInner ring 0+2B+C)/(TInner ring n-TInner ring n-m)]*m
Wherein, tTheory of the inventionIndicates the theoretical time length T required by the indoor environment temperature to reach the set temperatureInner ring 0Indicating the first acquired indoor ambient temperature, A, B, C are three temperature compensation values, T, setSetting upIndicating the set temperature, TInner ring nThe indoor environment temperature obtained at the current moment is represented, m is a positive integer not less than 1 preset according to actual requirements, and for example, m can be 6.
Further, three temperature compensation values can be set by a user or an air conditioner installer according to actual conditions, and the specific setting rule is as follows:
