Title:
The refrigerant system directly provided with the contact-heat-exchange machine
Document Type and Number:
Japanese Patent JP6249716
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerant system including a heat exchanger causing a first refrigerant to directly contact a second refrigerant receiving heat from the first refrigerant and transported to a heat load, and capable of being used for heating.SOLUTION: A refrigerant system 1 includes: a heat source cycle 40 that includes a compressor 11 compressing an HSC refrigerant, a first heat exchanger 12 implementing heat exchange between the HSC refrigerant and a heat source, and a decompression unit 14 decompressing a pressure of the HSC refrigerant; a heat transfer cycle 20 that includes a second heat exchanger 21 implementing heat exchange between a water refrigerant and a heat load, and a pump 23 pumping up the heat refrigerant; a direct-contact heat exchanger 50 for causing the HSC refrigerant flowing in the heat source cycle 40 to directly contact the water refrigerant flowing in the heat transfer cycle 20; and a separator 55 separating the HSC refrigerant decompressed and transferred from the direct-contact heat exchanger 50 from the water refrigerant. The heat source cycle 40 can rotate in a direction in which the HSC refrigerant discharged from the compressor 11 flows into the direct-contact heat exchanger 50.
