Self Evaporating Portable Air Conditioner

If you are tired of cleaning up spilled water or emptying the AC unit's water tray so often, it's time to get a fully self evaporating portable air conditioner!

This is the evolution of free standing air conditioners that don't have the problem of continually forming condensate that ends up filling a container that continually needs emptying.

What Self-Evaporating Air Conditioning Units Do


These clever air coolers actually do away with needing a condensed moisture container by enduring all the excess moisture created by the air conditioning process is pumped out of the unit through its exhaust vent hose to the outside.

This essentially reduces the amount of condensate that manages to drip into the container quite considerably. That means it won't fill up very often, so you won't need to empty it very often.

In fact, depending on the climate, it may not need emptying at all if the natural humidity is very low as is often the case in certain areas.

How does this type of cooler do this?

How Fully Self Evaporating Air Conditioners Work

The process involved in how a portable self evaporating air conditioner works is relatively simple. So if you're not actually a HVAC engineering student or you don't particularly care to know the technical details, here is a simplified explanation that should satisfy your curiosity well enough.

I'll first explain how the air conditioning process produces all the excess water to begin with.

The Refrigeration Process

Air at room temperature in most climates also contains a percentage of moisture as water vapor. You may have noticed this condensing on the outside of a glass of cold water.

That warm moisture-rich air is drawn into the AC unit and passed through a lattice of thin pipes filled with a chilled refrigerant gas. The air is similarly chilled and just like the outside of that cold glass, its moisture condenses on the cold pipes.

As large droplets form, they drip down into a container at the base of the unit.

This container must be emptied periodically as it fills to prevent it from overflowing. Most portable AC units have an audible alarm to warn you and then the unit shuts off until you empty the container.

The Self Evaporating Solution

Enter the solution to this problem: The self evaporating AC unit.

Instead of allowing condensate to accumulate into droplets, the moisture is re-evaporated by a patented technology and ultimately removed from the unit via the exhaust hose.

Some even more clever units take this process a step further by reusing or recycling the moisture to aid in cooling the coils, increasing the unit's efficiency before exhausting the re-evaporated moisture out of the vent.

Which is Better: Single or Dual Hose

The best, most efficient self-evaporating ACs tend to make use of a dual hose setup, reducing energy consumption. The second vent hose is used to draw air from outside into the unit, assisting the cooling process while maintaining better air freshness

It also eliminates negative pressure in the room, a problem suffered by single-hose units that draw air in only from the room.

When the pressure inside the room is less than outside, hot air from the outside can be drawn into the room through openings, cracks or loosely fitting glass panes in windows. This can force the AC to work harder to keep things cool inside, using more energy and costing more to run.

Therefore, a dual hose unit works more efficiently than a single-hose version. This is more noticeable in larger spaces to be cooled.

The purchase cost of dual hose AC models is often higher than single-hose models, but that cost is offset by energy savings over time.

Do You Want One Now?

My guess is that after reading about how these advanced, free standing air conditioners that self-evaporate work, you'll probably want to replace your old unit with a shiny new one, right!

Well, you can find and order them easily enough online from many popular online stores like Home Depot, Amazon, Lowes, Wal-Mart and my current preferred electrical appliance store, Sylvane (for their excellent after-sales service that you don't always get with some of the bigger general stores.
