The invention discloses an air conditioner control method, which belongs to the technical field of air conditioners. The control method includes: obtaining the target liquid outlet pressure of the second throttling device, the target liquid outlet pressure includes the corresponding liquid outlet pressure of the second throttling device when the refrigerant flowing back to the gas-liquid separator meets the air supply pressure requirement; Outdoor ambient temperature and radiator temperature; adjust the flow openings of the first throttling device, the second throttling device and the third throttling device according to the outdoor ambient temperature and radiator temperature, so that the initial liquid outlet pressure reaches the target liquid outlet pressure . The control method of the present invention realizes the heat exchange and cooling of the electric control element by controlling the heat exchange between the electric control element and the gaseous refrigerant flowing through the radiator, and at the same time, the flow opening of the throttling device can be adjusted according to the preset air supply temperature , so that this part of the refrigerant after heat exchange can meet the pressure requirements of the compressor to replenish air and increase enthalpy, and improve the overall performance of the air conditioner.
Description
technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method, device and air conditioner. Background technique [0002] For fixed-frequency or variable-frequency air conditioners currently on the market, when the air conditioner operates in summer when the outdoor temperature is too high, the enthalpy value of the refrigerant compressed by the compressor cannot meet the enthalpy value of the heat exchange, resulting in the refrigerant flowing into the condenser and the outdoor air conditioner. The heat exchange efficiency of the environment is reduced, so it is necessary to supplement the air to increase the enthalpy of the compressor; while the existing air supplement and increase the enthalpy mostly adopts the method of directly charging the refrigerant after heat exchange in the condenser of the outdoor unit into the compressor. The temperature of the refrigerant often cannot meet the best pres...
