Title:
ON-VEHICLE TEMPERATURE CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2023037282
Kind Code:
A
Abstract:
To provide an on-vehicle temperature control device which downsizes capacity of liquid-storage part and prevent deterioration of life and performance of a compressor.SOLUTION: An on-vehicle temperature control device 1 includes refrigerant circuits 2, 2a, 2b which connects the followings through a refrigerant piping: a compressor 5; a condenser 6; a liquid-storage part 7, 7a; a plurality of expansion valves 8a-8c; and a plurality of vaporizers 9, 9a-9e. The plurality of expansion valves 8a-8c and the plurality of vaporizers 9, 9a-9e are parallelly arranged. The refrigerant circuits 2, 2a, 2b are not provided with an electromagnetic valve 10 capable of cutting off flow of refrigerant with respect to large-volume vaporizers 9b, 9c whose internal space are largest among the plurality of vaporizers 9, 9a-9e. The refrigerant circuits 2, 2a, 2b are provided with electromagnetic valves 10, 10a, 10d capable of cutting off flow of refrigerant with respect to one or a plurality of small volume vaporizers 9, 9a, 9d other than the large-volume vaporizer 9b, 9c among the plurality of vaporizers 9, 9a-9e.SELECTED DRAWING: Figure 1
