PURPOSE:To reduce the facility cost and eliminate such trouble as blockade of drain pipes or water leakage by a method wherein water in an outdoor drain pan is sprayed over an indoor heat exchanger by using a water feed pump and a water feed pipe, and a hot pipe is provided on the bottom of the outdoor drain pan to evaporate water only in cooling operation. CONSTITUTION:Drain water 3 led into a drain pan 7 during cooling operation is evaporated by the drain pan 7 that is heated to a high temperature by a hot pipe 11. When the generating amount of drain water is larger than the evaporating amount, the drain water is dispersed by the circumference of a fan 4 together with air from a building. On he other hand, drain water is gener ated by an outdoor heat exchanger 5 during heating operation. The drain water generated is sent by a water feed pump 9 through a water feed pipe 10, and dripped from the heat exchanger 3, then it is splashed by the air flow from an indoor fan 2, evaporated by the heat exchanger 3, and mixed with the air in the room thus humidifying the air. Thereby, reduction in the facility cost of an air conditioner and elimination of trouble can be achieved. |
