|Title:||AIR CONDITIONER CONTROL METHOD, DEVICE AND AIR CONDITIONER|
An air conditioner control method, a control device and an air conditioner, the control method comprising the following steps: S101, obtaining a target liquid outlet pressure and the initial liquid outlet pressure of a second throttling device, the target liquid outlet pressure comprising the corresponding liquid outlet pressure of the second throttling device when refrigerants flowing back to a compressor meet a pressure requirement for air supply; S102, detecting outdoor ambient temperature and radiator temperature; and S103, adjusting the flow openings of a first throttling device, the second throttling device and a third throttling device according to the outdoor ambient temperature and the radiator temperature, so that the initial liquid outlet pressure reaches the target liquid outlet pressure. With the method, the heat exchange between an electronic control element and gaseous refrigerants flowing through a radiator is controlled so as to carry out the heat exchange and cooling of the electronic control element. At the same time, the flow opening of a throttling device may be adjusted according to a preset air supply temperature, so that part of the refrigerants after heat exchange meet the pressure requirement of a compressor for air supply and enthalpy addition, thereby improving the overall performance of the air conditioner.
