Title:
AIR CONDITIONING UNIT AND COMPRESSOR COOLING CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/082240
Kind Code:
A1
Abstract:
An air conditioning unit and a compressor cooling control method therefor, relating to the technical field of air conditioners, and aiming to solve the problem of poor compressor cooling control manner of an existing air conditioning unit. The air conditioning unit comprises a cooling branch and a main circulation loop; the cooling branch comprises a first cooling branch (15) and a second cooling branch (16), one end of the first cooling branch (15) is connected to a condenser (12), the other end of the first cooling branch (15) is connected to a cooling port (111) of a compressor (11), and the first cooling branch (15) is configured to be able to use pressure difference to introduce a liquid refrigerant in the condenser (12) into the compressor (11) to realize spray cooling; one end of the second cooling branch (16) is also connected to the condenser (12), the other end of the second cooling branch (16) is also connected to the cooling port (111), a cooling pump (162) is provided on the second cooling branch (16), and the second cooling branch (16) is configured to be able to use the cooling pump (162) to introduce the liquid refrigerant in the condenser (12) into the compressor (11) to realize spray cooling. Therefore, the cooling effect can also be guaranteed at all times while guaranteeing the energy saving effect.
