A humidity control apparatus (10) includes: a casing (11); exhaust and air-supplying fans (25, 26) and dampers (41-48, 83, 84) for exchanging the outside air and the room air with each other via air passageways (31-34, 37, 38, 81, 82) of the casing (11); and a refrigerant, circuit (50) for controlling the humidity of the air passing through the air passageways. The humidity control apparatus (10) further includes a controller (60) for monitoring an abnormality inside the apparatus and determining the type of the detected abnormality. When the detected abnormality is an abnormality related to the refrigerant circuit (50) and is not an abnormality related to the exhaust and air-supplying fans (25, 26) and the dampers (41-48, 83, 84), the controller (60) stops the refrigeration cycle of the refrigerant circuit (50) to shut down the humidity-controlling mode, and keeps the ventilation mode available. |
