Air conditioner

The utility model discloses an air conditioner which comprises a compressor, a reversing valve, an indoor heat exchanger and an outdoor heat exchanger. The first on-off valve is arranged between the exhaust port of the compressor and the first end of the reversing valve, and the second on-off valve is arranged between the fourth end of the reversing valve and the air return port of the compressor; the first high-pressure sensor is arranged between the first on-off valve and the first end of the reversing valve, and the second high-pressure sensor is arranged between the first on-off valve and an exhaust port of the compressor. In this way, by arranging the first on-off valve, the second on-off valve, the first high-pressure sensor and/or the second high-pressure sensor, refrigerant recycling can be achieved, and refrigerant waste is reduced. 本实用新型公开了一种空调器，包括：压缩机、换向阀、室内换热器和室外换热器；第一通断阀和第二通断阀，第一通断阀设于压缩机的排气口与换向阀的第一端之间，第二通断阀设于换向阀的第四端与压缩机的回气口之间；第一高压传感器和/或第二高压传感器，第一高压传感器设于第一通断阀与换向阀的第一端之间，第二高压传感器设于第一通断阀与压缩机的排气口之间。如此，
