To suitably suppress freezing of contacts of a mechanical relay.SOLUTION: A relay dehumidifier 1 includes a relay housing 22 that accommodates a mechanical relay body 21 and is individually communicated with a surge tank 30 and an evaporator 40, a solenoid valve 32 disposed in a first communication pipe 31 that communicates the surge tank 30 and the relay housing 22; an ECU 50, and the ECU 50 closes the solenoid valve 32 under a normal condition, and opens the solenoid valve 32 when the surge tank 30 generates negative pressure and the humidity at the outlet 40b of the evaporator 40 is below a predetermined value.SELECTED DRAWING: Figure 2

    【課題】メカニカルリレーの接点の氷結を好適に抑制する。【解決手段】リレー除湿装置1は、メカニカルリレー本体21を収容し、サージタンク30及びエバポレータ40と個別に連通されるリレー筐体22と、サージタンク30とリレー筐体22とを連通する第1連通管31に配置されるソレノイドバルブ32と、ECU50と、を備える。ECU50は、常態でソレノイドバルブ32を閉止させるとともに、サージタンク30が負圧を発生させ、かつ、エバポレータ40の出口40bが所定値以下の湿度の場合に、ソレノイドバルブ32を開放させる。【選択図】図2
