る除湿式乾燥装置。 In a dehumidifying drying device that has a cooling dehumidifier that dehumidifies and introduces outside air, and an exhaust port that exhausts dry indoor air that has become humid, the cooling dehumidifier is an evaporator installed in an air path that introduces outside air. A heat pump cycle is formed by a condenser, a condenser, a throttle, a compressor, a four-way switching valve that switches the flow direction of the refrigerant, and an outdoor heat exchanger connected in parallel to the evaporator via a solenoid valve. A dehumidifying drying device, characterized in that either the evaporator or the outdoor heat exchanger can be selected as the evaporator via the solenoid valve depending on the outside temperature.
