PURPOSE:To accumplish effective utilization of capacity of the air conditioning equipment while eliminating troublesomeness of control through automatic selection of amount of air sucked according to the condition or internal of extenrnal air. CONSTITUTION:The condition of internal or external air is detected with a sensor 1 and then, the signal detected by the sensor 1 is compared with the preset level with a comparator/amplified 2 and according to the output signal, a drive controller 3 is actuated to control the drive of an air intake door 4 serving as an internal/ external selector. With such an arrangement, it is possible to cool the inside of the room through a automatic switch to internal air suction when the external air temperrature is high, or when there is much mist inside the room, the mist is reduced by sucking external air enough to prevent fog on the window glass. |
