Title:
INTAKE AIR COOLING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/073769
Kind Code:
A1
Abstract:
According to the present invention, a variable compressor (31) of an intake air cooling system has variable output and compresses and discharges a refrigerant. A cabin cooling heat exchanger (32) cools refrigerant that has been discharged from the variable compressor (31). A cabin cooling decompression unit (34) decompresses and expands refrigerant that has flowed out from the cabin cooling heat exchanger (32). A cabin cooling evaporator (35) is provided for cabin cooling and evaporates refrigerant that has been decompressed and expanded by the cabin cooling decompression unit (34). An intake air cooling evaporator (37) is provided separately from the cabin cooling evaporator (35) and evaporates refrigerant that has been decompressed and expanded by the cabin cooling decompression unit (34) or another decompression unit. An intake air cooling heat exchanger (61) is provided on an intake air passage (47) and circulates cooling water that is for intake air cooling. A control unit (20) controls the operation of the variable compressor (31) on the basis of an air conditioning requested cooling output for a vehicular air conditioning device.
