ることを特徴とする恒温恒湿空気供給装置。 A humidifier, a refrigeration cycle cooler, and a heater are installed in the air flow path equipped with a blower, and by connecting to the space where the temperature and humidity are to be controlled through the air outlet and air inlet, it is possible to control the temperature and humidity of the space. In a constant-temperature and constant-humidity air supply device that circulates and supplies air, the expander of the refrigeration cycle, which consists of a refrigerant compressor, a condenser, an expander, and a cooler connected by a refrigerant circulation flow path, has a refrigerant evaporation temperature of 0°C. The expander specified below and the evaporation temperature of the refrigerant installed in parallel with the expander are set to 0°C.
A constant temperature control system consisting of a constant pressure expansion valve that regulates and maintains a larger pressure and an electromagnetic on-off valve, and which opens the electromagnetic on-off valve during temperature and humidity control operation to prevent frost from forming on the cooler. Constant humidity air supply device.
