There are several ways to drain the condensate water out of a portable AC. Some use gravitational draining to expel the water, while others collect it inside the built-in water reservoirs that you have to empty manually.
However, doing so can be tedious, especially for those who live in humid regions. The water buckets fill up quickly and need frequent emptying.
Manufacturers came up with self-evaporating technology that allows portable AC units to minimize their water output to rectify this problem.
Fully self-evaporative portable air conditioners can automatically evaporate the water and expel it through the external vent hose. So, there is no need for either manual or hose draining.
Self-evaporating units not only eliminate the need to drain water they also incorporate some clever tricks to get more from the cooling process than regular AC units. They use an advanced refrigeration process that reuses the condensed moisture to assist in cooling the air.
As the refrigeration cycle progresses, the internal components of the device, especially the condenser, become hot. These components evaporate the collected moisture and recycle it to keep the system cool. Doing so helps them save energy and lower operating costs.
Once it has served its purpose, the excess moisture is expelled out through the hot air exhaust.
