Title:
HOT WATER SUPPLY AIR-CONDITIONING SYSTEM
Document Type and Number:
Japanese Patent JP2016102598
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress degradation of a heating capacity of an indoor heat exchanger caused by liquid accumulation in the indoor heat exchanger.SOLUTION: A refrigerant circuit (20) has a compressor (21), an indoor heat exchanger (22), an outdoor heat exchanger (24), and an expansion valve (23) disposed in a liquid-refrigerant passage (PR1) connecting a liquid end of the indoor heat exchanger (22) and a liquid end of the outdoor heat exchanger (24). A refrigerant-water heat exchanger (40) is connected to a discharge side of the compressor (21) in the refrigerant circuit (20), and exchanges heat between the refrigerant discharged from the compressor (21) and water. A gas-liquid separator (50) is connected to a gas side of the indoor heat exchanger (22) in the refrigerant circuit (20), and separates the refrigerant which has passed through the refrigerant-water heat exchanger (40) into a gas refrigerant and a liquid refrigerant in a hot water supply heating operation, to supply the gas refrigerant to the gas side of the indoor heat exchanger (22) and to supply the liquid refrigerant to the liquid-refrigerant passage (PR1).SELECTED DRAWING: Figure 1
