METHOD FOR CONTROLLING MULTI-SPLIT AIR CONDITIONER, MULTI-SPLIT AIR CONDITIONER SYSTEM, AND COMPUTER-READABLE STORAGE MEDIUM

摘要

A method for controlling a multi-split air conditioner. The method comprising the steps of: step S10, detecting whether the degree of superheat of each outdoor unit meets a target requirement; step S20, if yes, determining whether a difference between an average exhaust temperature of each outdoor unit and an average exhaust temperature of an outdoor unit system reaches a preset value; step S30, if yes, comparing the size of the average exhaust temperature of each outdoor unit with the size of the average exhaust temperature of the outdoor unit system; and step S40, according to the result between the size of the average exhaust temperature of each outdoor unit and the size of the average exhaust temperature of the outdoor unit system, controlling an electronic expansion valve to actuate to make the average exhaust temperature of each outdoor unit to approximate to the average exhaust temperature of the outdoor unit system. By controlling the degree of opening of an electronic expansion valve, the problem of refrigerant maldistribution in a multi-split air conditioner system is resolved, and the exhaust temperature of the system is effectively controlled. Also disclosed are a multi-split air conditioner system and a computer-readable storage medium.
