What Is A Self-Evaporating Portable Air Conditioner & Its Benefits?

People never stop trying to make our lives easier, and the technology of portable air conditioners advances constantly. The vendor may have introduced self-evaporating portable ACs to you as the latest invention, but you don’t know what it is. 

This post will tell you everything you need to know about it, and you will see if you need a self-evaporating portable air conditioner after reading it.

Let’s get started!

What is a self-evaporating portable air conditioner?

A self-evaporating portable air conditioner, as the name implies, is a portable air conditioner that can evaporate moisture on its own and does not need to be drained like regular portable air conditioners.

Even though portable air conditioners are portable, they operate on the same principles as standard models. When hot and moist air enters the machine, it passes through an evaporator coil, which cools the air and condenses the excess moisture.

Moisture will convert vapor to liquid and accumulate in the water tray or tank, which must be drained on a regular basis. The machine can eliminate moisture by using self-evaporative technology, saving you time and effort in draining the water.

How does a self-evaporating portable AC remove moisture?

This is not a single clear-cut answer to this question since self-evaporating portable ACs may use different technology. There are two types of technology that are commonly seen in these units.

Recycle the moisture to maximize the cooling effect

The condensed water will be used to assist in cooling off the coil. When the water is heated up, it will evaporate and get out of the machine from the vent hose.

As a result, the amount of water remaining in the water tank will decrease over time, eliminating the need to drain it.

It is important to note that when the humidity level is too high, the moisture recycled may not be able to offset the excess water produced, which means that the AC may still need to be drained on a regular basis, even if it has an auto evaporation feature.

Internal misting system

The exhaust hose can be used to expel mist. Some manufacturers include an internal misting system that converts the collected water into tiny water particles that are then expelled to the outside.

Some portable air conditioners use only one technology, while others combine the two.

Types of self-evaporating portable air conditioners

Some portable air conditioners claim to use self-evaporating technology, but you may still need to drain the water. This is due to the fact that there are two types of self-evaporating portable air conditioners.

Partially Self-Evaporative ACs

This type of air conditioner can remove a great amount of condensate and send it out through the vent hose. However, some water is still left in the tray, meaning that you still need to drain it.

It may be adequate if you live in dry climates because the moisture removed from the air is limited.

Fully self-evaporative ACs

Fully self-evaporative ACs are more powerful than partially ones, and technically, they can remove all the collected water on their own.

That is to say, they are more suitable for people living in humid areas. Again, you may still need to drain the water under extreme conditions. 

Benefits of self-evaporating portable air conditioners

If you still haven’t made up your mind, you can take a look at its benefits and disadvantages.

No need to worry about draining the water

When using other types of portable AC, you must figure out how to drain the water. However, with a self-evaporating model, you no longer have to worry about it.

Even if there is no nearby floor drain, you can place it wherever you want. It is also beneficial for people with weak hands because the water tank does not have to be manually removed.

The machine will not turn off automatically

To protect the machine, a standard portable AC will shut off when the water tank is full via a float switch. You should estimate how often you should drain your portable air conditioner or drain the water through a drainage hose to ensure it can work continuously.

When using a fully self-evaporating model, the unit will no longer shut down due to a full tank.

Disadvantages of self-evaporating portable air conditioners

Self-evaporating models don’t have any significant drawbacks, but there are two potential disadvantages.

Higher price tag

If you are working on a budget, it may not be a perfect choice. Self-evaporating models, especially fully self-evaporating ones, tend to be priced higher than other models. 

Hard to repair

Because the AC involves more features, it adds difficulty to fix it. It is possible that the self-evaporating function can become faulty after a while, and it may take more effort to repair it.

Wrapping up

Understanding any fancy function of a portable AC can be difficult. However, self-evaporating technology is being used in an increasing number of portable air conditioners, and it is worth your time to learn more about it.

Simply put, self-evaporating portable air conditioning reduces or eliminates the need to drain the water, allowing it to operate continuously and is easier to set up. It can provide a hassle-free experience, which many of us value.
