PURPOSE:To decrease the quantity of drain to be generated and reduce the drainage disposal of the drain by disposing of the drain generated from an evaporator according to ambient,environments. CONSTITUTION:A condenser 1 of an air-conditioner having therein a freezing cycle comprising an evaporator, the condenser, a compressor and a pressure reducing device has a function of forcibly evaporating drain condensed by the evaporator 5. A flow passage is provided, which allows drain that has not been able to be evaporated by the condenser 1 to flow again to the condenser 1 with the aid of a drain pump and, in addition, a flow passage is provided, which allows drain that has not been able to be evaporated by the condenser 1 to be directly discharged to a drain tank and the like. Further, a change-over device for changing over the drain flow passage is provided for these flow passages in order to dispose of drain according to ambient environments. |
