AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To prevent dew formation in the vicinity of a humidification blowout port during stop of ventilation operation. SOLUTION: An air conditioner 1 capable of supplying air from an outdoor unit 3 to an indoor unit 2 via a humidification duct 12 includes: an indoor humidity sensor 20 detecting indoor humidity Hin; an indoor temperature sensor 21 detecting indoor temperature Tin; and a heater 34 provided in the outdoor unit 3 and heating air supplied to the indoor unit 2. When the ventilation operation for supplying air which is not humidified from the outdoor unit 3 to the indoor unit 2 is stopped, based on the indoor humidity Hindetected by the indoor humidity sensor 20 and the indoor temperature Tindetected by the indoor temperature sensor 21, dew-point temperature T0of indoor air is calculated. Before the ventilation operation is stopped, heating by the heater 34 is started so that temperature in the vicinity of the humidification blowout port 17 of the humidification duct 12 supplying air to the indoor unit 2 becomes higher than the dew-point temperature T0.
