Title:
AIR CONDITIONER AND REFRIGERATION CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/094841
Kind Code:
A1
Abstract:
An air conditioner, comprising: a compressor (7), an indoor heat exchanger (1) and an outdoor heat exchanger (2) connected by pipelines to form a loop, wherein a throttling device (4) is connected between the indoor heat exchanger (1) and the outdoor heat exchanger (2); a pipe between the outdoor heat exchanger (2) and the throttling device (4) is connected in parallel with any number of bypass branches (5); each bypass branch (5) is successively provided with a first switch valve (51) and a refrigerant storage (52). Also provided is a refrigeration control method for the air conditioner. When a high pressure value of the refrigerant in the air conditioner is too high, redundant refrigerant in a refrigeration loop of the air conditioner is stored by a bypass branch to reduce the pressure of refrigerant in the refrigeration loop until the high pressure value of the refrigerant meets requirements so that the air conditioner can normally refrigerate in high temperature and even super-high temperature environment, thereby effectively solving the problem that users cannot refrigerate in high temperature.
