Then, it is supplied into the store room.

  The dehumidification regeneration rotor 230 is coated with an adsorbent such as zeolite, and adsorbs moisture when the air supplied to the introduction passage 210 passes through the dehumidification regeneration rotor 230. At this time, moisture is condensed, and the air becomes low-humidity and high-temperature air.

  The cooling cooler 213 cools the air when the air supplied to the store room is higher than a desired temperature, and can supply air at a desired temperature with low humidity even in summer.

  The heating heater 214 heats the air when the air supplied to the store room is lower than a desired temperature, and can supply air at a desired temperature with low humidity even in winter.
