Description of the Related Art As a conventional method and apparatus for supplying constant temperature and constant humidity air of this type, a method disclosed in Japanese Patent Laid-Open No. 4-139345 is known. This conventional constant temperature and constant humidity air supply method humidifies the outside air introduced into the air flow path as necessary, and then cools and dehumidifies it to a temperature corresponding to the dew point of the air having the temperature and humidity conditions of the supply target, and then After the primary air is heated to a predetermined temperature lower than the target temperature to raise its temperature, the primary heated air is secondarily heated to the target temperature and then supplied.

スを生じていた。In the above-mentioned conventional technique, the cooler is always operated at a constant power regardless of the temperature and humidity of the inlet air of the air flow path and the temperature and humidity of the target outlet. The outlet air was not controlled. Therefore, considering the combination that requires the most cooling capacity depending on the temperature and humidity of the inlet air and the target temperature and humidity of the outlet air, the cooling capacity is always kept constant and the amount of cooling is calculated. It had to be reheated, resulting in two types of energy loss: cooling and heating.
