|1. (WO2018141132) AIR CONDITIONER CONTROL METHOD AND DEVICE, AND AIR CONDITIONER|
|Applicants:||QINGDAO HAIER AIR CONDITIONER GENERAL CORP., LTD.
|Title:||AIR CONDITIONER CONTROL METHOD AND DEVICE, AND AIR CONDITIONER|
An air conditioner control method and device, and an air conditioner, relating to the technical field of air conditioners. The control method comprises: acquiring a target liquid outlet pressure and initial liquid outlet pressure of a second throttling device; adjusting the flow opening of the second throttling device and a third throttling device so that the initial liquid outlet pressure reaches to the target liquid outlet pressure; acquiring a target air outlet pressure and initial air outlet pressure of a first throttling device, wherein the target air outlet pressure and the initial air outlet pressure are the pressures of a refrigerant input into a compressor by the first throttling device; and adjusting the flow opening of the first throttling device so that the initial air outlet pressure reaches the target air outlet pressure. The control method controls electronically controlled elements and the gaseous refrigerant flowing through a radiator to perform heat exchange, and adjusts, according to a preset air supply temperature, the flow opening of the throttling devices so that the refrigerant after the heat exchange can satisfy the pressure requirement for air supplying and enthalpy increasing of the compressor; therefore the overall performance of the air conditioner is improved.
