Abstract

A humidity control device (10) has a casing (11), air discharge and supply fans (25, 26) and dampers (41-48, 83, 84) for performing ventilation between outdoor air and indoor air via air paths (31-34, 37, 38, 81, 82) of the casing (11), and a refrigerant circuit (50) for controlling the humidity of air flowing in the air paths. The humidity control device (10) further has a controller (60) for monitoring abnormality in the device and determining the type of a detected abnormality. When a detected abnormality is an abnormality relating to the refrigerant circuit (50) and not an abnormality relating to the air discharge and supply fans (25, 26) and the dampers (41-48, 83, 84), the controller (60) stops a refrigeration cycle of the refrigerant circuit (50) to stop humidity control operation and enables ventilation operation.
