Title:
REFRIGERATION CYCLE APPARATUS
Document Type and Number:
Japanese Patent JP2022146159
Kind Code:
A
Abstract:
To provide a refrigeration cycle apparatus capable of achieving both of energy saving and secure of refrigeration capacity.SOLUTION: A refrigeration cycle apparatus includes: a compressor 11 for sucking, compressing and discharging refrigerant; a heat radiation unit 12 for radiating heat of the refrigerant discharged from the compressor; a first decompression unit 13 and a second decompression unit 16 for decompressing the refrigerant heat-radiated in the heat radiation unit; a first evaporation unit 14 for evaporating the refrigerant by allowing the refrigerant decompressed in the first decompression unit to absorb heat from air sent to air-conditioned space; a second evaporation unit 17 for evaporating the refrigerant by allowing the refrigerant decompressed in the second decompression unit to absorb heat from an object 33 to be refrigerated; and a control unit 60 for switching an energy saving mode for controlling the compressor so that the temperature TE1 of the first evaporation unit approaches an energy saving target temperature TEOe and a standard mode allowed to be executed when the target temperature TBO of the refrigeration target is less than an energy saving reference temperature αe to control the compressor so that the temperature of the first evaporation unit approaches the standard target temperature TEOs lower than the energy saving target temperature.SELECTED DRAWING: Figure 3
