Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2021188790
Kind Code:
A
Abstract:
To suppress fluctuation of a blowout air temperature.SOLUTION: A refrigeration cycle device includes: an air-conditioning expansion valve 14b decompressing a refrigerant of which heat has been radiated by a heat radiation part; an indoor evaporator 18 evaporating the refrigerant and cooling air by exchanging heat between the refrigerant decompressed by the air-conditioning expansion valve and the air; cooling expansion valves 14c, 14d disposed in parallel with the air-conditioning expansion valve in a flow of the refrigerant and decompressing the refrigerant of which heat has been radiated by the heat radiation part; cooling parts 19a, 19b cooling a cooling object by evaporating the refrigerant decompressed by the cooling expansion valves by using heat of the cooling object; and a control section 60 performing fluctuation suppression control for controlling at least one of refrigerant discharge capacity of a compressor and openings of the cooling expansion valves to suppress fluctuation of a flow rate of the refrigerant in the indoor evaporator when a first mode in which the refrigerant flows in the indoor evaporator and the refrigerant does not flow in the cooling parts is shifted to a second mode in which the refrigerant flows in the indoor evaporator and the cooling parts.SELECTED DRAWING: Figure 9
