In that case, the system switches intodefrosting operation to take away the frost.• During defrosting operation, hot air does not flow out of indoor unit.• This air conditioner cools the room by releasing the heat in the room outside. Therefore, the cooling performance of the airconditioner may be degraded if the outdoor temperature is high.• The computer chip works to rid the room of humidity while maintaining the temperature as much as possible.
