Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2019219133
Kind Code:
A
Abstract:
To suppress oil stagnation in a heat exchanger for battery cooling in a refrigeration cycle device in which a heat exchanger for air conditioning and the heat exchanger for battery cooling are arranged in parallel with respect to a refrigerant flow.SOLUTION: A refrigeration cycle device includes: radiators 12, 16 for allowing a refrigerant discharged from a compressor 11 to radiate heat; heat exchangers 16, 18 for air conditioner for absorbing heat from the air and evaporating the refrigerant; a chiller 19 arranged in parallel with the heat exchangers 16, 18 for air conditioning in the flow of the refrigerant which has radiated heat in the radiators 12, 16, and for absorbing heat from a heating medium circulating between itself and a battery 80 and evaporating the refrigerant; an expansion valve 14c for cooling for adjusting a decompression amount of the refrigerant flowing in the chiller 19; a refrigerant flow rate detection part 60f for detecting a flow rate V1 of the refrigerant flowing in the chiller 19; and a control device 60 for controlling the actuation of the expansion valve 14c for cooling so that the flow rate of the refrigerant detected by the refrigerant flow rate detection part 60f surpasses a predetermined reference flow rate VO.SELECTED DRAWING: Figure 1
