Dry mode is a setting on an air conditioner that is designed to remove excess moisture from the air in your living space. It is intended to be used when the conditions are humid and temperatures are not too hot. When the air conditioner is in dry mode, it sucks out moisture from the air, similar to a dehumidifier, lowering humidity and capturing moisture in the air, thus releasing fresh and breezy air. The humid or moist air from the room is sucked into the air conditioning unit, the air is then condensed in the evaporator, removing excess moisture, and the dry air is released back into the room to help lower the overall moisture. Dry mode works similarly to cooling mode, but it senses temperature differently. In cooling mode, the air conditioner is only concerned with cooling the room, whereas in dry mode, the unit will record the room temperature and decide at what temperature it will cycle off. Dry mode then considers and regulates with regard to the room/return air temperature and the cooling coil/heat exchanger temperatures. Fan and compressor speeds will be controlled to maintain the desired temperature. It is important to note that dry mode is not governed by your thermostats temperature reading, and it will stop running when your indoor temperature drops to a certain level. Dry mode is an energy-efficient way to regulate indoor humidity when outdoor humidity is high and for offsetting the extra moisture that is produced by lots of indoor traffic and moisture-generating activities.
