Title:
CONTROL METHOD AND SYSTEM FOR MULTI-SPLIT AIR CONDITIONER, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/051947
Kind Code:
A1
Abstract:
A method for controlling a multi-split air conditioner. The method comprises: detecting whether the degree of superheat of an outdoor unit meets a target requirement (S10); if yes, determining whether a difference value between an average exhaust temperature of the outdoor unit and the average exhaust temperature of an outdoor unit system reaches a preset value (S20); if yes, comparing the average exhaust temperature of the outdoor unit with the average exhaust temperature of the outdoor unit system (S30); reducing operating frequency of a compressor of the outdoor unit if the average exhaust temperature of the outdoor unit is greater than the average exhaust temperature of the outdoor unit system; and increasing the operating frequency of the compressor of the outdoor unit if the average exhaust temperature of the outdoor unit is less than the average exhaust temperature of the outdoor unit system (S40). The method resolves the problem in the multi-split air conditioner system of excessively high or excessively low exhaust temperature of the compressor of the outdoor unit due to uneven refrigerant distribution, and improves the reliability of the multi-type air conditioner system. Also disclosed are a multi-split air conditioner system (100) and a computer readable storage medium (101).
