In this case, the outdoor heat exchanger 11 serves as a condenser, the indoor heat exchanger 13 serves as an evaporator, and the high-temperature and high-pressure superheated steam is introduced into the condenser.
The superheated vapor of high temperature and high pressure is cooled in the condenser, and the superheated refrigerant changes from a gaseous state to a liquid state. The cooled low-temperature high-pressure refrigerant is throttled and depressurized by the throttling device 14, and a low-temperature low-pressure refrigerant liquid flows into the evaporator. The refrigerant liquid absorbs heat in the evaporator and vaporizes, the temperature of the ambient air temperature decreases, and cold air is blown into the room.

When water vapor generated by tap water is mixed into indoor air, the steam is very easy to gather with dust floating in the air, so that the effect similar to haze is formed, and therefore, the dust removal function needs to be performed in an indoor unmanned environment. After the steam and the floating and sinking are gathered, the air is induced through the air return opening, the dust water mist is sucked back to the air conditioner again, then the water mist is condensed by the indoor unit of the air conditioner, and condensed water is formed and then is discharged to the outside.
