PROBLEM TO BE SOLVED: To perform dehumidification in which indoor temperature does not increase while performing ventilation during high humidity time by solving the problem in which, when introducing outdoor air into a room by ventilation at high humidity time during a rainy season and the like, the outdoor humidity comes into the room together and it causes mold and the like, and when using a conventional reheating dehumidification method by using a refrigeration cycle for removing such humidity, blowout air temperature after dehumidification increases, and indoor temperature also increases.SOLUTION: When introducing outdoor air into a room by ventilation, the air is supplied into the room after dehumidification; however, as a path for supplying the outdoor air into the room by cooling and dehumidifying it and a path for radiating heat to the indoor air and exhausting it to the outside of the room are separated, dehumidified air can be introduced into the room without increasing the indoor temperature. Furthermore, by using in combination with a heat exchanger unit, more comfortable dehumidification and ventilation can be performed. 【課題】梅雨時などの高湿時に換気により室外空気を室内に導入する際に室外の湿気も室内へ入ってくるためカビ等の原因になる。このような湿気を取り除くための従来の冷凍サイクルを用いた再熱除湿方式では除湿後の吹出空気温度が上昇するため、室内温度が上昇するという課題があり、高湿時に換気をしつつ室内の温度を上昇させない除湿をおこなうことを目的とする。【解決手段】換気により室外の空気を屋内に導入する際に除湿をした後に室内へ供給するが、室外空気を冷却除湿して室内に供給する経路と室内空気に放熱して室外へ排気する経路を分離することで室内の温度を上昇させることなく除湿した空気を室内に導入することができ、さらに熱交換器ユニットとの組み合わせで使用することにより、より快適な除湿換気が可能となる。【選択図】図２
