S352, the air conditioner controls the third throttling device to be closed.
By adopting the method for controlling the air conditioner provided by the embodiment of the disclosure, the running state of the indoor heat exchange assembly can be accurately regulated according to the first temperature value and the temperature value acquired at other positions based on different running modes of the air conditioner, so that the running state of the indoor heat exchange assembly is more suitable for the use requirements of current users.
Under the condition that the air conditioner operates in a dehumidification mode, the refrigerant flows to the first indoor heat exchanger through the second indoor heat exchanger. At this time, the first indoor heat exchanger performs a dehumidifying operation, and the second indoor heat exchanger performs a heating operation. In order to avoid the occurrence of the condition of too low air outlet temperature, a second temperature value of the second end of the first indoor heat exchanger is obtained. And calculating a first temperature difference value between the first temperature value and the second temperature value, wherein the first temperature difference value is used for representing the superheat degree of the first indoor heat exchanger so as to determine the cold quantity generated by the current indoor first heat exchanger in the dehumidification process. At this time, according to the first temperature difference, the opening value of the second throttling device is adjusted so that the second indoor heat exchanger generates heat to neutralize the cold energy generated by the first indoor heat exchanger. Therefore, the air conditioner can not reduce the air outlet temperature in the dehumidification process, and the use experience of a user is improved. Wherein, the opening value of the second throttling device is positively correlated with the magnitude of the first temperature difference.
Meanwhile, the opening value of the third throttling device can be determined according to the indoor humidity value or the body sensing humidity value of the user. The third throttle device may also be adjusted to a maximum opening value to increase the speed of dehumidification. The opening degree of the third throttling means is not particularly limited here.
Under the condition that the air conditioner operates in a heating mode, the refrigerant flows to the first indoor heat exchanger through the second indoor heat exchanger. At this time, both the first indoor heat exchanger and the second indoor heat exchanger perform a heating operation. In order to ensure the accuracy of the air-conditioner air outlet temperature control, a target outlet temperature value of the air conditioner is obtained. And calculating a second temperature difference value between the first temperature value and the target outlet temperature value to determine the air outlet temperature of the air conditioner under the heat exchange efficiency of the current indoor heat exchanger. At this time, according to the second temperature difference, the opening value of the second throttling device is adjusted to adjust the heat generated by the first indoor heat exchanger. So that the air conditioner can realize rapid heating. Wherein the opening value of the second throttling device is inversely related to the magnitude of the second temperature difference.
Optionally, the air conditioner acquires a target outlet temperature value, including: the air conditioner determines a target outlet temperature value according to the indoor environment temperature value; or, the air conditioner determines a target outlet temperature value according to the temperature of the indoor user.
Therefore, in the process of operating the heating mode of the air conditioner, whether the outlet temperature of the air conditioner is proper or not can be better determined according to the current indoor environment temperature or the temperature of the indoor user. The target outlet temperature value is the sum of the indoor environment temperature or the temperature compensation value of the indoor user and is used for judging whether the heat generation amount of the indoor heat exchanger is reasonable or not.
The method for determining the compensation value of the air conditioner may be that the air conditioner obtains an indoor area value of the indoor vertical projection, and determines a temperature compensation value corresponding to the indoor area value according to the indoor area value. The air conditioner can also obtain the volume value of the indoor environment, and the temperature compensation value corresponding to the volume value is determined according to the indoor volume value. The air conditioner can also obtain the ventilation area of the door and the window in the opening state in the indoor environment, and the corresponding temperature compensation value is determined according to the ventilation area and the volume value of the indoor environment.
Optionally, in the case that the operation mode is a heating mode, the air conditioner controls the outdoor fan to be in a stopped operation state. The air conditioner reduces the refrigerant flow of the outdoor heat exchanger. Meanwhile, the third throttling device can be regulated to the maximum opening value, so that the heating efficiency of the air conditioner is further improved.
Therefore, the heat exchange efficiency of the outdoor heat exchanger can be reduced by closing the outdoor fan of the air conditioner. Meanwhile, the refrigerant flow of the outdoor heat exchanger is reduced, and the heat exchange efficiency of the outdoor heat exchanger can be further reduced. Thereby, the discharge temperature of the compressor is increased so that the air conditioner can rapidly heat.
Under the condition that the air conditioner operates in a refrigerating mode, the refrigerant flows to the second indoor heat exchanger through the first indoor heat exchanger. At this time, the first indoor heat exchanger and the second indoor heat exchanger both perform a cooling operation. In order to ensure the accuracy of the control of the air outlet temperature of the air conditioner, a third temperature value of the second end of the second indoor heat exchanger, namely the temperature value of the outlet end of the whole indoor heat exchange assembly, is obtained. And calculating a third temperature difference value between the third temperature value and the first temperature value, wherein the third temperature difference value is used for representing the superheat degree of the indoor heat exchanger assembly so as to determine the cold quantity generated by the current indoor heat exchanger assembly and further determine the air outlet temperature of the air conditioner. At this time, according to the third temperature difference, the opening value of the third throttling device is adjusted to adjust the cooling capacity generated by the indoor heat exchange assembly, so that the air conditioner can realize rapid refrigeration. Wherein, the opening value of the third throttling device is positively correlated with the magnitude of the third temperature difference.
Optionally, the air conditioner adjusts the opening value of the second throttling device to a preset opening value. Therefore, the refrigerant can flow in the first indoor heat exchanger and the second indoor heat exchanger rapidly, and the indoor heat exchange assembly can perform refrigeration operation integrally. The preset opening value may be a maximum opening that can be reached by the second throttling device. Or the corresponding opening value can be determined according to the temperature adjusting efficiency of the indoor heat exchange assembly required by the user.
Optionally, the air conditioner adjusts the opening degrees of the second throttling device and the third throttling device through a PID (process, integration, differentiation) algorithm according to the calculated temperature difference. Therefore, the problem that the indoor heat exchanger is greatly impacted due to overlarge opening degree adjustment in the adjustment process can be effectively avoided.
Under the condition that the air conditioner operates in the air supply mode, the air conditioner controls the second throttling device and the third throttling device to be in a closed state. At this time, the indoor heat exchange assembly does not perform heat exchange. So that the air conditioner can realize the air supply operation.
