PURPOSE:To discharge drain water surely without providing the titled controller with a water level detecting sensor by putting a drain pump ON at all times upon starting a compressor. CONSTITUTION:Drain water, generated by condensing in a heat exchanger 1, is reserved in a water receiving pan 2, however, is discharged to the outside of a machine by a drain pump 3 controlled by a controller 4. The drain pump 3 repeats ON/OFF operation periodically by the controller 4. When a compressor effect ON/OFF operation, thereafter, the ON/OFF operation of the drain pump is repeated again. According to this method, the drain water may be discharged surely to the outside of the compressor. |
