Air conditioner

摘要

An air conditioner has a refrigeration cycle and a regulating circuit. The refrigeration cycle includes a compressor of variable exhaust amount type, a 4-way valve connected to the discharge side and suction side of the compressor, indoor-side and outdoor-side heat exchanges connected to the valve, and an expansion valve of a motor-driven tape. The regulating circuit regulates the flow rate of refrigerant into the indoor or outdoor side heat exchanger by adjusting the opening degree of the expansion valve in response to the amount of the refrigerant exhausted from the compressor, thereby setting the temperature of the refrigerant to be discharged from the compressor to a predetermined temperature responsive to the exhaust amount of the compressor.
