, and a non-dehumidifying area N are provided. The high dehumidification region S is a setting region where the humidity setting value H is relatively low and strong dehumidification is performed regardless of the output of the hygrometer 5. The non-dehumidification area N is an area where both the temperature setting value T and the humidity setting value H are high and no dehumidification is performed at all regardless of the hygrometer output. The low dehumidification region W is a region where the temperature set value T and the humidity set value H are between the blue regions S and N, and weak dehumidification is performed regardless of the hygrometer output.

A humidity controller 6 is installed in the hygrometer 5 and humidifier 7 in the constant temperature and humidity tank l.
Connect. The humidity controller 6 processes the humidity setting value and the output of the hygrometer 5, and provides a humidity control signal ph of a required magnitude to the humidifier 7. Further, a humidity controller 6 and a dehumidifier 8 consisting of a plurality of freezing dehumidifiers 8a and 8b in this case are connected to the dehumidification control means 12.

This corresponds to a state in which D2 and D2 do not exist, the opening/closing devices 10a and 10b are cut off, and the refrigerating and dehumidifying machines 8a and 8b are all stopped. In the low dehumidification operation, only one of the drive signals D1 or D2 from the dehumidification control means 12 exists, and therefore one of the switching devices 10a or 10b is turned on and one refrigerating dehumidifier 8a is operated.
Or it corresponds to a state where only 8b is operated. Further, the high dehumidification operation corresponds to a state in which both the drive signals D1 and D2 from the dehumidification control means 12 are present, and therefore both the switching devices 10a and 10b are turned on and the refreezing dehumidifiers 8a and 8b are operated.

If the humidity control signal ph from 2 fluctuates significantly,
It is more practical to make the above switching judgment after averaging the values of the humidity control signal ph over a certain period.
