Abstract
An air conditioner has a heat source refrigerant circuit, utilization refrigerant circuits, a pressurizing circuit, and a cooler. The heat source refrigerant circuit is configured by an interconnection of a compression mechanism, a heat source heat exchanger, and a heat source expansion valve that reduces a pressure of refrigerant condensed in the heat source heat exchanger. The pressurizing circuit is disposed in the heat source refrigerant circuit and causes high-pressure gas refrigerant compressed in the compression mechanism to merge with a refrigerant having a pressure that is reduced in the heat source expansion valve. The refrigerant is sent to the utilization refrigerant circuits. The cooler cools the refrigerant having the pressure that is reduced in the heat source expansion valve.
Claims8
An air conditioner comprising:
- a heat source refrigerant circuit configured by an interconnection of a compression mechanism, a heat source heat exchanger, and a heat source expansion valve that reduces a pressure of refrigerant condensed in the heat source heat exchanger when the heat source heat exchanger functions as a condenser;
- one or more utilization refrigerant circuits connected to the heat source refrigerant circuit and configured by the interconnection of a plurality of utilization heat exchangers and a plurality of utilization expansion valves;
- a pressurizing circuit disposed in the heat source refrigerant circuit and configured to cause high-pressure gas refrigerant compressed in the compression mechanism to merge with a refrigerant having a pressure that is reduced in the heat source expansion valve, the refrigerant being sent to the utilization refrigerant circuits;
- and
- a cooler for cooling the refrigerant having the pressure that is reduced in the heat source expansion valve.
