Additionally, since the cleaning nozzle is opened in the cleaning step, the first heat exchanger 31 can be cleaned with washing water. Since the opening of the cleaning nozzle means the result of washing water being discharged or sprayed through the cleaning nozzle, it is not limited to opening the flow path of the cleaning nozzle itself. Specifically, opening the washing nozzle may include both the flow control unit operating to guide condensate discharged from the drain pump to the washing nozzle so that washing water is discharged through the washing nozzle, and the washing valve opening the washing nozzle. there is.
  • the washing water may flow into the second heat exchanger (32) when the circulation fan (36) is operated in the later stage.
