Title:
REFRIGERATION SYSTEM AND CONTROL METHOD AND CONTROLLER THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/140962
Kind Code:
A1
Abstract:
A refrigeration system (1000) and a control method therefor. The refrigeration system (1000) comprises an evaporator (1001) and a condenser (1002) connected by means of a pipeline to form a circulation loop. The refrigeration system (1000) further comprises an air discharge pipeline (1003). The inlet end of the air discharge pipeline (1003) is connected to the outlet end of the condenser (1002), and the outlet end of the air discharge pipeline (1003) is connected to the inlet end of the evaporator (1001). An air discharge means (1004) is provided on the air discharge pipeline (1003), and the air discharge means (1004) is used for discharging air in a working medium flowing through the air discharge pipeline (1003). The evaporator (1001) is used for cooling an apparatus to be cooled. Most of the working medium output by the condenser (1002) is or evenly the entire working medium is liquid, and therefore, the air in the working medium output by the condenser (1002) is discharged, it is possible that only a small amount of refrigerant is discharged, or even no refrigerant is discharged. Thus, erroneous discharge of the refrigerant can be effectively reduced.
