Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2020085382
Kind Code:
A
Abstract:
To provide a refrigeration cycle device enabling reduction of manufacturing costs by simplifying the configuration.SOLUTION: A refrigeration cycle device 1 capable of simultaneously performing cabin interior air-conditioning and battery cooling includes a compressor 2, a condenser 3, a first decompression mechanism 4, a second decompression mechanism 5, a battery evaporator 6, an air-conditioning evaporator 7 and an evaporation pressure regulating valve 8. A refrigerant compressed by the compressor 2 is condensed by the condenser 3 and decompressed by the first decompression mechanism 4 and the second decompression mechanism 5. The battery evaporator 6 cools a battery by using evaporation heat of the refrigerant that has flowed out of the first decompression mechanism 4. The air-conditioning evaporator 7 generates air-conditioned air for cabin inner air-conditioning by using evaporation heat of the refrigerant that has flowed out of the second decompression mechanism 5. The evaporation pressure regulating valve 8 is provided in the middle of piping that connects the battery evaporator 6 with the compressor 2 to maintain the evaporation pressure of the refrigerant flowing in the battery evaporator 6 at a higher level than that of the refrigerant flowing in the air-conditioning evaporator 7.SELECTED DRAWING: Figure 1
