- Patent Literature 1 Japanese Patent Laid-Open No. 2007-024377
- the present disclosure provides a humidity controlling device that quickly performs release of humidity from humidity controlling means, thereby achieves a rapid start-up, and can improve performance for a humidity controlling amount.
- a humidity controlling device in the present disclosure is a humidity controlling device including: a housing; air supply side heat exchanging means that is disposed in an internal portion of the housing and is provided in an air supply flow path which supplies air to an air-conditioning target space; air discharge side heat exchanging means that is disposed in the internal portion of the housing and is provided in an air discharge flow path which discharges air to an outside; and humidity controlling means that is provided in the air supply flow path and the air discharge flow path, is rotated in a predetermined direction by a humidity controlling means driving unit, and forms a rotor shape, in which the air discharge side heat exchanging means includes air-discharge-side heat-exchanging-means inlet piping into which a cooling-heating medium flows and air-discharge-side heat-exchanging-means outlet piping from which the cooling-heating medium flows out, and the air-discharge-side heat-exchanging-means inlet piping is positioned below the air-discharge-side heat-exchanging-means outlet piping.
- a humidity controlling device in the present disclosure, because air flowing through an air discharge flow path passes through air-discharge-side heat-exchanging-means inlet piping having a highest temperature and is sent to humidity controlling means, at the moment when the humidity controlling means moves from an air supply flow path to the air discharge flow path, the humidity controlling means can be heated by air having the highest temperature.

- the inventors have found a problem that when air passes through insides of the air supply flow path and the air discharge flow path and heat exchange is performed between sensible heat of both of the air supply flow path and the air discharge flow path via a total heat exchanger, supplied air caused to flow as laminar flow by the total heat exchanger is cooled by a cooling coil, and discharged air caused to flow as laminar flow heats the disc-type humidity controlling material via a heating coil, but because of its uniform heating temperature, release of humidity from the disc-type humidity controlling material is slow, and a humidity controlling amount lowers.
