Abstract
An air conditioner is disclosed which includes a pressurizer for pressurizing a suction-side refrigerant sucked into a compressor, and an auxiliary condenser for condensing a discharge-side refrigerant discharged out of the compressor. Accordingly, it is possible to raise the evaporation pressure of the suction-side refrigerant sucked into the compressor, and to reduce the condensation pressure of the discharge-side refrigerant discharged out of the compressor. As a result, the difference between the suction and discharge pressures of the compressor can be reduced, so that a reduction in compression load can be achieved. Thus, a reduction in power consumption can be achieved.
Claims20
An air conditioner comprising:
- at least one compressor which compresses a refrigerant to a high-temperature and high-pressure gas state;
- a condenser which condenses a discharge-side refrigerant, which is the refrigerant gas discharged out of the compressor, to a liquid state;
- an expansion device which expands the refrigerant liquid emerging from the condenser;
- an evaporator which evaporates the refrigerant liquid emerging from the expansion device to a gas state;
- and
- a pressurizer which is arranged between the evaporator and the compressor, to pressurize a suction-side refrigerant which is the refrigerant sucked into the compressor after emerging from the evaporator.
