Title:
REFRIGERANT CIRCUIT DEVICE
Document Type and Number:
Japanese Patent JP2019027601
Kind Code:
A
Abstract:
To provide a refrigerant circuit device capable of improving thermal efficiency of a refrigerant and supplying hot water with a higher temperature.SOLUTION: A refrigerant circuit device includes: a compressor 1 for compressing a refrigerant; a hot water condenser 2 for exchanging heat between the refrigerant compressed by the compressor 1 and water to generate hot water; and a gas-liquid heat exchanger 3 that has an inner pipe 3a and an outer pipe 3b and in which the refrigerant that has passed through the hot water condenser 2 is introduced to the inner pipe 3a. The refrigerant circuit device also includes: a supercooling heat exchanger 4 for supercooling the refrigerant that has passed through the inner pipe 3a; an expansion valve 5 for decompressing the refrigerant that has passed through the supercooling heat exchanger 4; and a cold water evaporator 6 for exchanging heat between the refrigerant decompressed by the expansion valve 5 and water to generate cold water. The refrigerant that has passed through the cold water evaporator 6 is introduced to the outer pipe 3b to undergo heat exchange with the refrigerant passing through the inner pipe 3a, and then is introduced to the compressor 1.SELECTED DRAWING: Figure 1
