(57) [Problem] To provide a four-way valve cooling device for an air conditioner having a high cooling effect. SOLUTION: The refrigerant discharged from a discharge port of a compressor is: A four-way valve (4) having a pilot solenoid valve (11), an outdoor heat exchanger, an expansion mechanism, an indoor heat exchanger, and a heat pump refrigeration cycle circulating through the four-way valve (4) to the suction port of the compressor; In the four-way valve of the air conditioner, which selects heating or cooling by switching the refrigerant flow path by energizing the refrigerant, the solenoid coil 12 of the pilot solenoid valve 11 and the outlet of the four-way valve 4 to the suction port of the compressor are provided. The tube is thermally connected by a heat conductor. |
