One end of the plurality of first heat exchangers 3 is connected to the compressor 1 through the four-way valve 2, and the other ends of the plurality of first heat exchangers 3 are connected to the compressor 1 through the first electronic expansion valve 16. The second heat exchanger 5 is connected; the air outlet position of the compressor 1 is provided with a pressure sensor 6, and the pressure sensor 6 is used to collect the discharge pressure value of the compressor 1; ...

Embodiment 2

[0071] In one embodiment, an air conditioner is provided, such as figure 2 As shown, the air conditioner includes a compressor 1, a four-way valve 2, a plurality of first heat exchangers 3, a first electronic expansion valve 4, and a second heat exchanger 5, which are sequentially connected through pipelines. The heat exchangers 3 are connected in parallel, and the refrigerant inlet ports of each of the first heat exchangers 3 are respectively provided with second electronic expansion valves 4, and one end of several first heat exchangers 3 passes through the four-way valve 2 and The compressor 1 is connected, and the other ends of several first outdoor heat exchangers 3 are connected to the second heat exchanger 5 through the second electronic expansion valve 4; the air outlet position of the compressor 1 A pressure sensor 6 is provided, and the pressure sensor 6 is used to collect the discharge pressure value of the compressor 1; the air outlet position of the second heat e...

Embodiment 3

[0075]In one embodiment, an air conditioner control method is provided. The air conditioner control method can be applied to an air conditioner, and a processor in the air conditioner can execute the control method to control the air conditioner. Please refer to image 3 , image 3 It is a flowchart of an embodiment of the air conditioning control method provided by the present invention. The methods include:

[0076] S100. Obtain the exhaust pressure value and the outlet air temperature of the compressor.

[0077] When the air conditioner is in the low-temperature cooling state, due to the low outdoor temperature, the exhaust and condensation pressures are too low. In order to ensure that the compressor exhaust pressure is within the operating range, the outdoor machine frequently enters the start-stop state; when the air conditioner is in the high-temperature heating state, Due to the high indoor and outdoor temperatures, the exhaust and condensing pressures are too high, ...

Abstract

The invention discloses an air conditioner control method, an air conditioner and a storage medium. The method includes: obtaining the exhaust pressure value and the air outlet temperature of a compressor; determining the second electronic device according to the exhaust pressure value and the air outlet temperature The target opening number of expansion valves; controlling several second electronic expansion valves to operate according to the target opening number. The present invention controls the opening number of the second electronic expansion valve according to the discharge pressure value of the compressor and the air outlet temperature, and then controls the number of the first heat exchangers participating in the heat exchange of the air conditioner, so that when the air conditioner is in a low-temperature refrigeration state, it can stabilize Compressor exhaust pressure to avoid frequent start and stop of the compressor; when the air conditioner is in a high-temperature heating state, it can reduce the refrigerant evaporation and compressor suction volume, and prevent the exhaust and condensation pressure from exceeding the compressor pressure operating range, thereby improving the air conditioner. The service life of the compressor.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method, an air conditioner and a storage medium. Background technique [0002] Air conditioners are favored by users because of their temperature-regulating functions, and have become a must-have electrical appliance in the home. With the popularization of house heating and computer room air conditioning, in order to ensure constant temperature and humidity, low-temperature refrigeration and high-temperature heating have become necessary functions of air conditioners. [0003] When the air conditioner is in the low-temperature cooling state, due to the low indoor and outdoor temperature and the good heat exchange effect of the condenser, the exhaust and condensation pressure is too low. In order to ensure that the compressor exhaust pressure is within the operating range, the outdoor machine frequently enters the start-stop state ; When the ai...
