REFRIGERATION CYCLE DEVICE AND HOT WATER GENERATION DEVICE INCLUDING THE SAME
Document Type and Number:
Japanese Patent JP2018179346
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigeration cycle device which is energy saving and which has excellent reliability, by performing optimum control of an operation of a compressor.SOLUTION: A refrigeration cycle device 1A includes: a refrigerant circuit 2 in which a compressor 21, a radiator 22, a decompression device 23 and an evaporator 24 are connected in an annular manner; a utilization side heating medium circuit 50 in which a utilization side heating medium flows via the radiator 22; a first temperature sensor 61 for detecting the temperature of a refrigerant discharged from the compressor 21; a second temperature sensor 62 for detecting the temperature of the utilization side heating medium; and a control device 3. When the discharge temperature detected by the first temperature sensor 61 is at least below the utilization side heating medium temperature detected by the second sensor 62, the control device 3 determines the rotational frequency of the compressor 21 based on the discharge temperature and the utilization side heating medium temperature. By performing optimum control of an operation of the compressor 21, the refrigeration cycle device 1A which is energy saving and which has excellent reliability can be provided.SELECTED DRAWING: Figure 1
