Portable Air Conditioners Vent Free

Updated on July 14, 2015

Ductless Portable Air Conditioners

When the temperatures soar and it gets uncomfortably hot, a good air cooler is the only solution. There are portable air conditioners that are vent free which means you can move them around the house from room to room without needing to vent hot exhaust air to the outside.

Do you think that you might want one of these amazing air cooling solutions? You don't have to, but it's certainly an option.

True portability in an air conditioning unit is limited in many models because they need to vent their hot exhaust to the outside, or they would end up causing a net increase in the temperature of your room. But these ventless portable air conditioner units work in a different way and have no hot exhaust air.

This lens explores the simplicity and amazing effectiveness of these truly portable air cooling units that provide you with a real, cost effective solution to keeping cool and comfortable when the weather is really hot and uncomfortable.

What Are Swamp Coolers?

Truly ventless or ductless portable air coolers are not true air conditioning units in the sense that they do not use a refrigerant gas in a heat exchanger to create cool air. As such, they also don't produce any hot exhaust air and so don't need to have a duct or vent to the outside. You can find out more about them here: www.orocta.org/mobility/ventless-and-portable-air-conditioner.html and see the difference.

The correct term is "Evaporative Air Cooler" although they are better known as "Swamp Coolers" and they work very simply by evaporating moisture as air is passed across a damp membrane and the resulting air is cooled. A high speed fan is the only moving part in these simple units, so they only use a fraction of the energy that a true portable air conditioning unit uses to run.

Are There Any Disadvantages?

The only downside to this type of air cooler is that it loses its effectiveness when the humidity of the air increases. In areas of high humidity, I'm afraid you're stuck with the more expensive air cooling solution of a true air conditioner, as a swamp cooler will not be able to cool already moist air very effectively.

The reason for this is that the air needs to be fairly dry for the "cooling by evaporation" process to be effective. In areas of naturally dry heat, this isn't a problem and swamp coolers can drop the temperature in a hot room by as much as 30 degrees or so.

So before you rush out to buy on of these units, you should check the relative humidity of your area, which is easy enough to do online by checking the local weather reports.
