Why You Need a Mini Air Conditioner & How They Work

When the weather is boiling hot outside, an air conditioner is a great way to instantly cool down your space in a matter of seconds. Air conditioners have been around for a while now and there are a lot of different options on the market today when it comes to air conditioners. The most common types of air conditioners include built-in wall units or air conditioners that you place in your window during the warmer months. But what if you need cool air quickly and on the go. 

There are actually mini air conditioners that are specifically meant for this purpose. Mini air conditioners offer good ventilation and allow you to break up some of the hot summer air that makes entertaining, catching up with friends and family, and outdoor activities a little uncomfortable, more bearable. Whether you use the device inside or outside on a screen-in porch, mini best portable air conditioners can be a great gadget to have during the summer months. 

To get started though, let’s talk about what air conditioners are and how they work…

What Are Air Conditioners? 

Air conditioning or also known as A/C or air con is the process of removing heat and moisture from the inside of a space and adding cooler air to space instead. Air conditioning is used both in domestic and commercial environments and is used to make the environment a little bit more comfortable for not only humans but animals as well. It can help to cool space but also dehumidifier rooms as well. This humidity is not only caused by the temperature outside, but also technology like computer servers and other electronic devices that emit heat when functioning. 

How They Work 

Air conditioners typically use some sort of fan to distribute the conditioned air to the space around you. Whether you’re in a car or your home, this process is done to improve the quality of the air and make it much more comfortable. The electric refrigerant-based AC units range from a variety of sizes including smaller models to simply cool down a bedroom or larger systems for commercial units. 

The cooling of the room is typically done through the refrigeration cycle and sometimes during a passive cooling system where evaporation or free cooling is traditionally used. AC systems can also be made based on desiccants which are chemicals that remove the moisture in the air. The construction of the AC unit solely depends on what you’re looking for, the size of the space you’re looking to condition the air for, and your budget as well. 

The Difference Between Mini Air Conditioner and Regular Size 

So now you know how an air conditioner works, you may be wondering what is the difference between a mini air conditioner and a regular, traditional size air conditioner. Portable mini air conditioners are mostly just compact fans and typically include a sponge inside to make the air around you cooler and less humid. They are small in size and usually, battery-powered, which makes them, well, portable perfect for the work commute or traveling on the go. 

These mini best portable air conditioners can use either a single USB-rechargeable battery or several standard ones, like AA. Rechargeable models are more convenient and have a longer life on a single charge but in case you go hiking or something, it might be easier to stock up on batteries than finding an outlet so it just depends on your needs and your intended purpose. 

A personal air cooler or mini air conditioner is an evaporative air cooler that pulls the warm air from your room and runs through the cool water it has in its tank. It then releases the cold air to decrease both the temperature, but also the humidity in the room as well. 

With being so small, you may be wondering how effective are they really. When comparing to using a fan on a hot day, a mini air conditioner does work significantly better with making the room temperature a bit more comfortable due to the fact that it not only cools the temperature of the room a bit but also reduces the humidity levels. The way fans work is they just circulate the already existing air in the room which improves the comfortability of the room, but doesn’t decrease the temperature or humidity at all.
