How Do Desktop Air Conditioners Work?

Air conditioners allow you to set the temperature of your room, according to your preference, even on the hottest of days. There are many types of air conditioners available in the market today. Out of these, desktop air conditioners come in really handy. 

They extract the warm air from the room in a heat exchange process and use a cooling chemical that helps with compression and condensation and then releases the heat energy. Modern units also feature climate control, which lets the user set the temperature to a precise degree.

Characteristics of Our Favorite Desktop Air Conditioners

While choosing the best desktop air conditioner for your home or office, there are some main features that should be kept in mind. These will help you maximize the utility of the unit and enjoy the perks. Listed below are some of these:

Tank Capacity

First of all, you need to know where you’ll be using the air conditioner. Once you know that, you can choose the unit accordingly. More tank capacity means your unit can run for longer periods of time. It also depends upon the temperature you set the air conditioner on. Higher modes use more water while setting it on a low-mode will make the water last longer. 


The portability of the unit matters a lot. Whether you are able to move it around or not decides how much you will be able to use it. If the air conditioner is compact in size, you can pick it up and take it from your study room to your TV lounge easily and vice versa. 


If a unit comes with all the top-notch features but is difficult to operate, it will hinder its usefulness. So, you should look for an air conditioner that is easy to operate and doesn’t require a lot of technical skills to install. Instead, it should be more of a plug-n-play unit.

Aspects to Consider Before Buying

When you go into the market, there are a variety of models available with lots of high-tech features and units in multiple shapes and sizes. It can get a bit confusing for you. Therefore, in order to help choose a suitable unit, below we’ve discussed some important aspects to consider before making your purchase decision.

Size and Weight

The most important things to consider are the dimensions and weight of the air conditioner. If you wish to place the unit in a designated place, you need to precisely measure the available area and its surroundings.

Moreover, if you’re planning on moving the unit around frequently, you should go for an air conditioner that is light and easy to carry around. It’ll be easy for you to take it with you to any room without much effort. 


A noisy air conditioner can really be a nuisance for anybody, especially if you have one in your office. All units are somewhat noisy, but you need to be careful about where you’ll be using yours. Many manufacturers offer quieter air conditioners, so you should check the unit's decibel level before buying it.


As we’ve already discussed, there are a variety of models available with top-notch features. You need to carefully choose the features that will suit your usage. Some manufacturers offer useful features like three-in-one cooling, humidifying, and purifying functions, while others have heating capabilities when it gets cold.

Desktop vs Portable AC - Comparison Overview

Desktop and portable ACs have the same primary goal: to cool the room on hot summer days. However, they both use different mechanisms to achieve the desired result. In this section, we’ll talk about the similarities and differences between the two. 


First of all, the main difference between the two is how they operate. Portable ACs use a hose-based system to filter out hot air and cool the air present inside the room. Some portable ACs use a single hose, while others may have a dual hose system, depending on the unit's model and type. 

On the other hand, desktop air conditioners remove the hot air from a room and use a cooling chemical that helps with compression and condensation. Then it releases the heat energy, and eventually, this whole heat exchange process lowers the temperature in the room.


If we look at the accessibility, it’s clear that both are designed to be highly portable. You can easily move either of them to whatever place you desire, especially because they are light in weight. 

Additionally, the installation process of both is quite straightforward and requires no advanced technical know-how. 


After having a detailed look at the list of the best desktop air conditioners and discussing the various important aspects related, we hope that this article will help you choose a suitable unit. Just remember that buying the most expensive unit doesn’t mean it will be the best for you; even a moderately-priced unit can do the job.
