Abstract

The invention provides a control method for an air-conditioning system, and the air-conditioning system. The method comprises the following steps of after a closing instruction for an expansion valveof an indoor unit is received, controlling the expansion valve to run to reach a closed state; judging whether a heat exchanger of the indoor unit is in a running state or not; and when the heat exchanger is in the running state, judging that the closed state of the expansion valve is invalid, wherein the expansion valve has an opening degree which is not zero in the closed state. According to thecontrol method for the air-conditioning system, and the air-conditioning system, by judging the current state of the heat exchanger after the expansion valve runs to reach the closed state, whether the expansion valve is closed or not can be rapidly and effectively detected, and then the undesirable phenomena of liquid backflow, noise, frosting and water dripping, and the like caused due to thatthe expansion valve is not effectively closed are avoided, so that the reliability of the air-conditioning system is ensured.

Description

technical field [0001] The present invention relates to the field of refrigeration equipment, and more specifically, to a control method of an air-conditioning system, an air-conditioning system, and a computer-readable storage medium. Background technique [0002] As one of the four major components in the air conditioning system, the electronic expansion valve is widely used and its importance is self-evident. In a multi-connected system, each indoor unit has its own electronic expansion valve, so that the overall circuit of the indoor unit can be cut off by closing the electronic expansion valve in a different indoor unit. When the electronic expansion valve cannot be effectively closed, it will cause adverse phenomena such as liquid return, noise, frosting and dripping, which not only greatly affects the normal use of the user, but also causes great damage to the reliability and life of the air conditioning system. Contents of the invention [0003] The present invent...
