Title:
METHOD AND SYSTEM FOR CONTROLLING AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2023/029954
Kind Code:
A1
Abstract:
The present invention relates to the technical field of air conditioner control, and specifically provides a method and system for controlling an air conditioner, aiming at solving the problem that existing air conditioners cannot satisfy refrigeration requirements at different ambient temperatures. For the objective, the method for controlling the air conditioner in the present invention relates to controlling, according to an outdoor ambient temperature, a connection state of a first four-way valve and a second four-way valve, and an on/off state of a first electromagnetic valve to change a refrigerant flow path formed by a compressor, a first outdoor heat exchanger, a second outdoor heat exchanger, and a third outdoor heat exchanger, so as to change the temperature of a refrigerant in the flow path and further change the temperature of the refrigerant in a liquid refrigerant pipeline of an indoor unit, such that the refrigeration capability, such as a refrigeration air supply temperature, of the indoor unit is changed, thereby implementing different refrigeration requirements at different ambient temperatures.
