Title:
CONTROL METHOD FOR AIR CONDITIONING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/184615
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of air conditioners, and specifically relates to a control method for an air conditioning system. In the present invention, an actual supercooling degree value of an air conditioning system is calculated on the basis of an acquired actual pressure value and actual temperature value of a refrigerant at a second end of an outdoor heat exchanger during cooling, or of an acquired actual pressure value and actual temperature value of a refrigerant at a first end of an indoor heat exchanger during heating; then, the actual supercooling degree value is compared with a preset target supercooling degree value; and the amount of the refrigerant participating in circulation in the air conditioning system is selectively controlled on the basis of a comparison result. Thus, the aim of flexibly adjusting the amount of a refrigerant participating in circulation in an air conditioning system can be more efficiently achieved, thereby more reliably improving the operation efficiency of the air conditioning system.
