特徴とする空気調和装置。[Claims for Utility Model Registration] The discharge port Po of the compressor 14 having an intermediate pressure port Pm, the outdoor heat exchanger 15, the pressure reducing device 16, the indoor heat exchanger 17, and the suction port Pi of the compressor 14 are connected in sequence by piping. In an air conditioner including a four-way switching valve 20 for switching the refrigerant circulation direction between the first pipe 18 connected to the discharge port Po and the second pipe 3 connected to the suction port Pi, the above-mentioned The above-described on-off valve 1 communicates the intermediate pressure port Pm with the pipe on the suction port Pi side from the four-way switching valve 20 via the bypass pipe 2, and has a spring 8 made of a shape memory alloy and opens at a certain temperature or below. The bypass pipe 2 is interposed in the bypass pipe 2, and heat is transferred between the bypass pipe 2 on the intermediate pressure port Pm side from the on-off valve 1 and the second pipe 3a on the indoor heat exchanger 17 side from the four-way switching valve 20. An air conditioner characterized in that it can be replaced.
