What is a Portable Air Conditioner?

Now that we’ve had a look at the best portable air conditioners of this year, let’s talk a little more about the technical details behind these units.

In short, a portable air conditioner is a detached and self-contained air cooler that is perfect for cooling areas of varying sizes. But how does it work?

Most residential models attach to your window via a hose. This hose collects the air from outside and runs it through a conditioning process.

The conditioning process, or refrigeration cycle, requires a number of components to function.

  • condensing coil
  • expansion valve
  • evaporator coil
  • compressor

With all these components working together in unison, the internal chamber of the air conditioner gets icy cold as the air starts to circulate inside. Once the air is sufficiently chilled, the AC unit pumps it out into your room.

It only takes a few minutes for small rooms to start to cool down. Plus, when the perfect temperature has been reached many ACs will automatically maintain the atmosphere!


How to Use a Portable Air Conditioner

One of the main selling points of a portable air conditioner is that it can move around from room to room without much hassle. Compared to other types of coolers such as window ACs, this gives you ultimate freedom and flexibility.

Setting up portable air conditioning units is a breeze due to the simple installation process of attaching the hose exhaust to the window opening. If you follow the instructions correctly, it will most likely only take a few minutes to get up and running.

Plus, most portable air conditioners are designed to cool your room in as little a just a few minutes! That’s hard to beat.

What to Look for in a Portable Air Conditioner

There are a ton of different options when it comes to choosing the best portable air conditioner for your space. You’ll have to look at the size, features, and most noteworthy- the cooling capabilities of the unit you’re thinking about installing.

How do portable air conditioners measure power?

Powering Portable AC Units

BTUs are the measurement of power for most types of air conditioners. The BTU measurement indicates how much heat the air conditioner can remove from a room. Generally speaking, the higher the BTUs the more powerful the AC.

We’ve put together a few recommendations for choosing the right portable air conditioner for your space. Keep in mind that these are base stats and you may want to go a little higher for some wiggle room (and be sure to keep in mind ceiling height).

BTU Sizes:

  • 8,000 BTUs will cover roughly 200 sq/ft
  • 10,000 BTUs will cover roughly 300 sq/ft
  • 12,000 BTUs will cover roughly 400 sq/ft
  • 16,000 BTUs will cover roughly 600 sq/ft

Aside from the actual power of your unit, you should also consider energy efficiency. Low BTU units usually take up less energy. In contrast, some high powered ACs are built to be really good on your wallet (and the environment). Energy Star certification is always a good starting point.

Noise can play a huge factor as well. Always check out the reviews to make sure that the noise level is tolerable.
