초록 ▼

In an air conditioning apparatus employing a heat pump system in which a cooling evaporator and a heating condenser are disposed inside the compartment. A compressor is provided with a gas injection port, a fixed throttle for reducing pressure of refrigerant on high pressure side in a refrigerating cycle to middle pressure, and a gas-liquid separator for separating the middle pressure refrigerant of which pressure is reduced by the fixed throttle. The gaseous refrigerant separated by the gas-liquid separator is introduced into the gas injection port. In a heating operation, the refrigerant circulates through the compressor, the condenser, the fixed throttle, the gas-liquid separator, an expansion valve, an outdoor heat exchanger, and the compressor as a closed circuit, while the gaseous refrigerant separated by the gas-liquid separator is injected into the compressor through the gas injection port. As a result, when the outside air temperature is low, the heating capacity is improved.
