Will air-conditioned rooms dry in summer? What about air-conditioned rooms It will dry a little. During the refrigeration process, the air conditioner can remove some moisture from the air. Because the temperature of indoor air drops sharply after entering the air conditioner evaporator, its relative humidity will enter a supersaturated state. At this time, a large amount of dew will condense on the evaporator fins, which is "condensation" in refrigeration terminology. Therefore, the refrigeration process is accompanied by dehumidification. Because of the dehumidification function of the air conditioner, The indoor air humidity is much lower than the normal value, and the room becomes dry. If the air in the room is too dry due to opening the air conditioner
