How Do Portable AC Systems Work?

There are many different systems in which AC units work. The ones on this list are built with basic technology. They pass the air through their water curtains to generate cold vapors. Compact, they should be used in smaller spaces, such as the ones mentioned above. Some other portable AC systems feature more advanced technologies. These can cool the air in larger spaces. For example, they work at 12,000 BTUs, taking the air from outside through one or two hoses. When buying more advanced air conditioning systems, you get a refrigerant system that cools the air and also a compressor because the refrigerated air needs to be compressed. The units will also feature a fan for moving the air. This is also how traditional AC systems work. They take air from outside, cool it via refrigeration, compress it, then circulate it. Opt for an advanced AC unit if you have larger spaces to cool. But keep in mind such machines are noisy, not to mention others use a lot of energy. Another thing that’s not good about them is that they dehumidify the air. There are many different ways in which portable AC systems work, too. These pieces of technology also humidify the air, which is a great advantage. What’s different about them too is that they don’t refrigerate or compress the air. Here are the main steps in which they work:

Step 1: The hot and dry air from outside is drawn in through one side.

Step 2: The unit passes the air taken in through its water curtain. This water curtain stays connected to a chamber for hydration or an ice tray. The water curtain stays cool and moist at all times.

Step 3: When the water curtain passes the air through it, then the water inside of it begins to evaporate. Evaporation doesn’t take place without any heat. Through the evaporation process, the heat gets removed. This way, the temperature becomes cooler, whereas the air turns out to be cleaner.

Step 4: In this last step, the fan blows and moisturizes the air. Lower temperatures are spread in your surroundings without any problem.

And that’s about it! Many portable AC units also feature an UV light, have filters for bacteria, and many other very advanced features. Most of them, though, are following only the steps mentioned here to function.
