Abstract (en)
Some known air conditioning systems occasionally make a user discomfort due to abnormal noise resulting from a collision of dew water with outside air in an air supply pipe when condensation occurs in the air supply pipe in an air-supplying operation. An air conditioning system (100) includes an air supply fan (54), an air supply pipe (35), a heater (52), and a control unit (16). The control unit (16) controls the air supply fan (54) and the heater (52). The control unit (16) switches an air-supplying operation to a first air-supplying operation and a second air-supplying operation. The first air-supplying operation involves heating outside air with the heater (52) and supplying the heated outside air into a room, in accordance with a concentration of a predetermined gas in the room. The second air-supplying operation involves supplying outside air into the room without heating the outside air, in accordance with the concentration of the predetermined gas in the room.
