An air conditioner characterized by being connected to a valve opening/closing body. (2) The air conditioner according to claim 1, wherein a coil spring is provided in the refrigerant pipe on the discharge side of the compressor. (3) The air conditioner according to claim 1 or 2, wherein the coil spring is made of a bidirectional shape memory alloy. (4) The coil spring is formed of a unidirectional shape memory alloy, and a bias spring is provided that operates the opening/closing body in the opposite direction to the coil spring, and the biasing force of the coil spring is equal to the bias force of the bias spring when the coil spring is in the all-stenite phase. The air conditioner according to claim 1 or 2, wherein the air conditioner is set to be larger than the biasing force, and smaller than the biasing force of the bias spring when in the martensitic phase.
