Title:
INTAKE AIR COOLING SYSTEM
Document Type and Number:
Japanese Patent JP2019070357
Kind Code:
A
Abstract:
To provide an intake air cooling system capable of improving cooling efficiency of intake air.SOLUTION: A compressor 31 provided in an intake air cooling system can vary output thereof, and compresses and discharges a refrigerant. A condenser 32 cools the refrigerant discharged from the compressor 31. A cabin cooling expansion valve 34 decompresses and expands the refrigerant caused to flow out from the condenser 32. A cabin cooling evaporator 35 is disposed to cool a cabin, and evaporates the refrigerant decompressed and expanded by the cabin cooling expansion valve 34. An intake air cooling evaporator 37 is disposed separately from the cabin cooling evaporator 35, and evaporates the refrigerant decompressed and expanded by the cabin cooling expansion valve 34 or other expansion valves. An intake air cooling heat exchanger 61 is provided in an intake passage 47, and has intake air cooling coolant circulating therein. An ECU 20 controls an operation of the compressor 31 on the basis of air conditioning request cooling output from a vehicular air conditioner.SELECTED DRAWING: Figure 1
