(54) VENTILATION DEVICE


(57) A problem to be solved by the present disclosure is a countermeasure against dew condensation in a silencer. In an air conditioner (1), a CPU (81) performs a drying operation of drying an inside of a silencer (62). Since the silencer (62) is detachable, time for the drying operation varies depending on whether the silencer is installed in a supply and exhaust duct (61). The CPU (81) controls the time for the drying operation to be longer when the silencer (62) is installed in the supply and exhaust duct (61) than when the silencer (62) is not installed in the supply and exhaust duct (61).
