CIRCULATION SYSTEM FOR AIR CONDITIONER, AIR CONDITIONER, AND AIR CONDITIONER CONTROL METHOD

A circulation system for an air conditioner, an air conditioner, and an air conditioner control method. The circulation system for an air conditioner comprises a compressor (1), a first heat exchanger (4), a second heat exchanger (14), and a gas-liquid separation assembly. The gas-liquid separation assembly forms a loop together with the compressor (1), the first heat exchanger (4), and the second heat exchanger (14); the gas-liquid separation assembly comprises two or more gas-liquid separators which are connected in series; the gas-liquid separation assembly is used for performing gas-liquid separation on a refrigerant. According to the technical solution, gas-liquid separation can be performed on the refrigerant flowing back to the compressor (1) two or even more times, so that the problem that oil returning to the compressor (1) contains liquid can be effectively solved. L'invention concerne un système de circulation pour un climatiseur, un climatiseur et un procédé de commande de climatiseur. Le système
