Abstract

The invention discloses a method and a device for controlling an air conditioning system, and belongs to the field of air conditioning technology. The control method comprises the following steps of:obtaining an outdoor temperature Tao and an outdoor humidity RH; determining, according to the outdoor temperature Tao and the outdoor humidity RH, a start-stop state of the third throttle device of the cooling branch and a valve degree at the time of opening. The method for controlling the air conditioning system provided by the invention can determine, according to the outdoor temperature and the outdoor humidity condition, whether to open the operation of the cooling branch, so as to use the electric control member with high temperature to heat the refrigerant flowing back to a reservoir, thereby increasing the compressor return air temperature and delaying the attenuation of the heating capacity of the air conditioning system.

Description

technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to a control method and device for an air conditioning system. Background technique [0002] When current air-conditioning products are operated under severe cold conditions in winter, due to the low outdoor temperature and humidity, the heating effect of the air-conditioning is poor, the outdoor unit is prone to frost, and its heating capacity is attenuated. It will lead to poor user experience. Therefore, how to improve the heating performance of the air-conditioning system during winter operation has always been an important research topic in the field of air-conditioning. Contents of the invention [0003] The invention provides a control method and device for an air-conditioning system, aiming at solving the problems that the air-conditioning system is prone to frosting and the heating performance decreases when it operates under low-temperature conditions in...
