What Does Self Evaporating in Air Conditioners Mean?

Air Conditioners and Humidity

• Even with normal human functions such as sweating and actions such as cooking and bathing, the interior relative humidity level goes up. Humidity is the moisture in the air, which is in the invisible form of water vapor. Air conditioners remove this moisture while they work, which is why traditional window air conditioners need to be slightly sloped down towards the outside. This way, the moisture, which is converted into liquid form inside the unit, can drain to the outside and collect inside a container, which is often a bucket that needs to be emptied daily when the air conditioner is being used.

Self-evaporating Difference

• While you need to either manually empty an outside container of collected water or empty the unit's water collection tray, with regular units, an air conditioner with self-evaporating technology reduces or eliminates this need. These units are also called no-drip units because the water does not drip from the rear of the unit. Instead, the unit recycles approximately half of the condensed water and uses it to cool off the inner cooling coils, which allows the unit to run more efficiently. It then disperses, or evaporates, the remaining water into the outside air, along with the hot air that you can normally feel exiting the back of all portable air conditioners. What a self-evaporating unit does is simply cut out any unnecessary water collecting inside the unit or in an outside container.

Self-evaporating Maintenance

• If the room in which the air conditioner is installed has high humidity, the condensation inside the unit might build up faster than the unit can recycle it and send it into the outside air. Under extreme conditions like this, you need to manually empty the water out of the small tray or tank located inside the self-evaporating unit.

Helping the Unit's Efficiency

• You can take actions to help lower the indoor humidity yourself and stop the self-evaporating unit from being overloaded with compressed water that you must empty yourself. Variations in the humidity in the air determine how fast the unit's water tray fills up. Invest in a hygrometer, which measures humidity and lets you know when the level is too high. Use vent fans in bathrooms and kitchens and also use a dehumidifier in rooms.
