in step S01, in the air conditioner dehumidification mode, the ambient humidity is acquired.
In an embodiment, when a user sets the air conditioner to the dehumidification mode, it is generally aimed to perform humidity adjustment of an indoor environment using the air conditioner. However, when the air conditioner performs humidity adjustment, the indoor environment temperature is often adjusted synchronously, and at this time, the acquired indoor environment temperature is used for further setting the air conditioner in the dehumidification mode, so as to adjust the indoor environment temperature in the dehumidification mode at the same time. Embodiments of the present disclosure thus provide a control method for dehumidification of an air conditioner that is a control flow enabled when the air conditioner is operating in a dehumidification mode.
And step S02, when the ambient humidity meets a first condition, controlling the air conditioner to enter a temperature compensation mode for increasing the ambient temperature according to the current ambient temperature.
The first condition is used to describe a condition related to setting humidity, and different humidity thresholds can be assigned to the first condition according to different seasons, temperatures, weather conditions and other conditions. Therefore, the intelligent control of the air conditioner is realized, when the indoor environment humidity where the user is located and the set humidity have a certain difference value, the current environment temperature is compensated, the dehumidification mode of the air conditioner is adjusted, the problem of air supercooling caused by excessive dehumidification is prevented, and the air conditioner enters the temperature compensation mode capable of improving the environment temperature.
And step S03, controlling the air conditioner to exit the temperature compensation mode when one or more of the ambient temperature, the ambient humidity and the stop operation time of the indoor fan meet a second condition.
By adopting the control method for the dehumidification of the air conditioner, whether the air conditioner meets the temperature compensation mode entering condition or not can be judged according to the ambient temperature on the basis that the ambient humidity meets the condition in the dehumidification mode of the air conditioner, so that the temperature reduction condition in the dehumidification process can be compensated, and the temperature adjustment precision in the dehumidification process of the air conditioner can be effectively improved; and one or more reference factors in the ambient temperature, the ambient humidity and the stop operation time of the indoor fan are judged to control the air conditioner to exit the temperature compensation mode, so that the adverse effect of the air conditioner on the refrigeration performance of the air conditioner is improved when the air conditioner operates in the dehumidification mode, particularly when the air conditioner operates in summer for dehumidification.
Optionally, the first condition includes: the difference between the ambient humidity and the set humidity is greater than 5% of the set humidity. Here, through setting for the difference relation of ambient humidity and set for humidity to realize the intelligent control to the air conditioner, when making the indoor ambient humidity that the user was located and setting for humidity to have certain difference, compensate current ambient temperature, realize the adjustment to the dehumidification mode of air conditioner, prevent to appear excessively dehumidifying and lead to the problem of air undercooling, make it enter into the temperature compensation mode that can improve ambient temperature.
According to different seasons, temperatures or weather conditions, different humidity thresholds can be selected in the first condition, for example, when the room temperature reaches 28 ℃, the difference between the ambient humidity and the set humidity can be selected to be greater than 3% of the set humidity; and when the room temperature reaches 18 ℃, the difference value between the ambient humidity and the set humidity can be selected to be more than 8% of the set humidity. According to different indoor temperature conditions, the incidence relation between the indoor environment temperature and the first condition can be preset in an electric control board of the air conditioner, so that the first condition corresponding to the temperature can be called when the indoor environment is at a certain temperature, the intelligent control of the air conditioner is realized, the indoor environment where a user is located can reach the optimal temperature and humidity condition, and the problem of air supercooling caused by excessive dehumidification is prevented.
Optionally, the controlling the air conditioner to enter the temperature compensation mode for increasing the ambient temperature according to the current ambient temperature includes controlling the air conditioner to enter the temperature compensation mode for increasing the ambient temperature when the ambient temperature is less than or equal to the set temperature; otherwise, controlling the air conditioner to continuously perform dehumidification. Therefore, under the dehumidification mode, the intelligent control of the air conditioner is realized according to the ambient temperature, the indoor environment where a user is located can reach the optimal temperature and humidity condition, and the problem of air supercooling caused by excessive dehumidification is prevented.
Optionally, the first temperature compensation parameter of the temperature compensation mode is determined according to a difference between the current ambient temperature and the set temperature. Here, the first compensation parameter for compensating the temperature during the dehumidification process is determined according to the different temperature difference values, and may also be preset in the electric control board of the air conditioner, so that the first compensation parameter may be determined according to the real-time ambient temperature, so as to implement the intelligent control of the air conditioner.
Optionally, obtaining the first temperature compensation parameter of the temperature compensation according to the outdoor environment temperature includes: acquiring a corresponding first temperature compensation parameter from a preset first incidence relation according to the difference value between the environment temperature and the set temperature; the preset first incidence relation comprises a difference value of the ambient temperature and the set temperature and a corresponding relation between the difference value and one or more of the rotating speed, the opening degree and the frequency of the compressor of the internal machine; the first compensation parameter comprises a first target frequency of the compressor, a first target opening degree of the throttling device and a first rotating speed of the internal machine.
Here, the first correlation includes a relationship between one or more temperature differences (which refers to a difference between the ambient temperature and the set temperature) and the first target frequency of the compressor, for example, a corresponding relationship between an optional temperature difference and the first target frequency of the compressor is shown in table 1, as shown in the following table:
| temperature difference (Unit:. degree. C.) | Compressor first target frequency (unit: Hz) |
| a1<△T≤a2 | h1 |
| a2<△T≤a3 | h2 |
| a3<△T≤a4 | h3 |
TABLE 1
In the first association relationship, the temperature difference value is in positive correlation with the first target frequency of the compressor, and the smaller the value of the temperature difference value is, the lower the first target frequency value of the compressor is; and the larger the value of the temperature difference value is, the higher the first target frequency value of the compressor is.
Optionally, the first association relationship further includes a relationship between one or more temperature difference values and a first target opening degree of the throttling device, where the temperature difference value and the first target opening degree of the throttling device are negatively correlated, and the smaller the value of the temperature difference value, the higher the first target opening degree of the throttling device is; and the larger the value of the temperature difference, the lower the first target opening degree of the throttle device.
Optionally, the first association relationship further includes a relationship between one or more temperature difference values and a first rotation speed of the internal machine, where the temperature difference value and the first rotation speed of the internal machine are in positive correlation, and the larger the value of the temperature difference value, the higher the first rotation speed of the internal machine is; and the smaller the value of the temperature difference, the lower the first rotation speed of the internal machine.
Optionally, the controlling the air conditioner to enter a temperature compensation mode for increasing the ambient temperature according to the current ambient temperature includes: determining a first target frequency of the compressor, a first target opening degree of the throttling device and a first rotating speed of the inner fan according to the current environment temperature; controlling the compressor to increase the frequency according to the first target frequency; controlling the opening degree of the throttling device to be reduced according to the first target opening degree; and after the opening degree of the throttling device is reduced, the inner fan is controlled to run at a first rotating speed for a first set time, the inner fan is controlled to stop running, and the guide plate is turned upwards. In this way, the compressor is controlled to be boosted to the first target frequency, so that the refrigerant flow rate is increased; meanwhile, the opening degree of the throttling device is reduced, so that the refrigerant can perform sufficient heat exchange; after the opening degree of the throttling device is reduced, the inner fan is controlled to run at a first rotating speed at a low speed for a first set time and then is stopped, the low-wind-speed running avoids overlarge air outlet to influence user experience, and meanwhile, the temperature of the heat exchanger is ensured not to be reduced under the condition that the requirement of indoor air circulation is met; make the heat exchanger temperature rise rapidly after interior fan shuts down, the baffle upwards overturns simultaneously, avoids cold wind or hot-blast direct-blowing user. The temperature rise of the indoor heat exchanger is realized so as to compensate the indoor temperature in the dehumidification mode.
In this embodiment, the first target frequency of the compressor, the first target opening of the throttling device, and the first rotation speed of the inner fan in the first temperature compensation parameter may also be adjusted according to set values, for example, the first target frequency of the compressor in the temperature compensation mode is controlled to be 80Hz, the first target opening is 140 steps, the first rotation speed of the inner fan is controlled to be F1, and the first set time of the inner fan is controlled to be 2 min.
In this embodiment, the first frequency increasing speed for controlling the frequency increasing of the compressor may be further determined according to a temperature difference between the ambient temperature and the set temperature. The temperature difference value is positively correlated with the first frequency increasing speed for controlling the frequency increasing of the compressor, and the smaller the numerical value of the temperature difference value is, the slower the first frequency increasing speed for controlling the frequency increasing of the compressor is; and the larger the value of the temperature difference value is, the faster the first frequency increasing speed for controlling the frequency increasing of the compressor is. In other embodiments, the frequency increasing speed of the compressor may be adjusted according to a set value, for example, the compressor is controlled to increase the frequency at a speed of 2 Hz/s. The air conditioner can select one of the incidence relations according to actual needs to determine the corresponding frequency increasing rate.
The optional second condition includes: the environment temperature is greater than the set temperature, the environment humidity is less than the set humidity, and the stop operation time of the indoor fan is greater than one or more of the set time. By setting a plurality of conditions for exiting the temperature compensation mode, the temperature compensation mode can be exited in time after temperature compensation adjustment, and air humidity is continuously adjusted. The dehumidification function of the air conditioner is not influenced by adjusting the temperature while the phenomenon of excessive temperature reduction in the dehumidification process is prevented. Optionally, the internal fan outage time greater than the set time may be set to be greater than 10 minutes.
Optionally, the controlling the air conditioner to exit the temperature compensation mode includes: acquiring a second target opening degree of the throttling device according to the environment temperature; and controlling the opening degree of the throttling device to be increased to the second target opening degree, and controlling the guide plate of the indoor unit to reset. Here, acquiring the second target opening degree of the throttle device based on the ambient temperature includes: and acquiring a second target opening degree of the corresponding throttling device from a preset second incidence relation according to the real-time environment temperature. In the second association relationship, the ambient temperature is in positive correlation with a second target opening degree of the throttling device, and the higher the value of the ambient temperature is, the higher the second target opening degree of the throttling device is; and the lower the value of the ambient temperature, the lower the second target opening degree of the throttle device. Since the ambient temperature at this time is the temperature at which the air conditioner exits the temperature compensation mode, and the air conditioner is to resume the dehumidification mode, when the opening degree of the throttling device is set according to the ambient temperature, the opening degree of the throttling device is increased against the increase of the ambient temperature, so that the flow rate of the refrigerant is increased, and the heat exchange capacity of the heat exchanger is improved. In other embodiments, the second target opening degree of the throttle device may be adjusted according to a set value, for example, the second target opening degree of the throttle device may be controlled to 460 steps. The air conditioner can select one of the incidence relations according to actual needs to determine the corresponding target opening degree of the throttling device.
The method comprises the following steps of acquiring the rotating speed of an indoor fan, the position of a guide plate, the frequency of a compressor and the opening degree of an electronic expansion valve in a dehumidification mode of the air conditioner as the preparation state of the air conditioner; and when the opening degree of the throttling device is increased to a second target opening degree, controlling the air conditioner to recover to the preparation state after controlling the indoor fan to operate at a low speed for a second set time. Wherein the second set time may be 30 s.
Optionally, the method further includes periodically detecting whether the ambient humidity meets a first condition; wherein the detection period is determined according to the difference between the ambient temperature and the set temperature. Therefore, the control of the interval time of entering the temperature compensation mode twice is realized, and the condition that the normal use of the air conditioner is influenced by the frequent stop of dehumidification operation of the air conditioner and the entering of the temperature compensation mode is prevented.
By adopting the control method for the dehumidification of the air conditioner, whether the air conditioner meets the temperature compensation mode entering condition or not can be judged according to the ambient temperature on the basis that the ambient humidity meets the condition in the dehumidification mode of the air conditioner, so that the temperature reduction condition in the dehumidification process can be compensated, and the temperature adjustment precision in the dehumidification process of the air conditioner can be effectively improved; and one or more reference factors in the ambient temperature, the ambient humidity and the stop operation time of the indoor fan are judged to control the air conditioner to exit the temperature compensation mode, so that the adverse effect of the air conditioner on the refrigeration performance of the air conditioner is improved when the air conditioner operates in the dehumidification mode, particularly when the air conditioner operates in summer for dehumidification.
