In few words, this article will be your comprehensive guide to understanding the desert coolers and how to choose one. So without any further delay, let’s start with the Desert air cooler definition.

What is a Desert Air Cooler?

Desert air coolers can be defined as air coolers designed to keep the entire room cool, not just the bed it serves. They give the best results when placed outside the window, but work in-house to ensure they are placed at doors, or windows where they can extract outside air and don’t depend on the air inside a closed room

The cooling performance of desert air coolers depends on many factors, the main two being their place of installation, as explained above, and the climatic conditions under which they are operated. Desert air coolers are designed to give the best performance in dry hot summers with minimum humidity. Their efficiency decreases with rising humidity, 50% being a deciding humidity mark.

How does a Desert Cooler work?

Desert air coolers work on the principle of evaporating the cool water inside the reservoir and circulating it into the room to make the room cool. Evaporation is better when the air is hot and dry, giving higher cooling efficiency. Because of the enhanced evaporation, these air coolers are also called “Evaporative coolers

Let’s understand the working principle of desert air coolers with the infographics.

Hot air from the environment is pulled by the fan. As it passes through the side panels containing cooling pads, hot air comes in contact with the water on the cooling pad. The water, for its contact with hot air, evaporates into cold vapours. These cold vapours are pulled by the fan and circulated into the room making it cool.

Why is it called a Desert Cooler?

The term “Desert” is symbolic of the Desert air coolers. It symbolises the effectiveness of desert air coolers in hot climatic conditions that we see in desert lands. The desert summers are hot and dry, and the wind breezes without obstructions. Desert air coolers are designed to meet the cooling needs of these conditions.

On the other hand, on hot but humid days, desert coolers are less effective as the air on the cooling pads doesn’t evaporate for outside humidity. 

What are the advantages of using Desert Air Coolers?

Besides a better alternative to air conditioning, desert air coolers offer the below-outlined advantages.

  1. Air Coolers are designed to cover large areas. It can be used smartly to cool master bedrooms or large halls, including the drawing room. A user needs to select the cooler capacity smartly to ensure effective cooling. For example, A 200 Square feet room would need a 40 to 50 L capacity desert air cooler to cool the room effectively.
  2. Desert coolers consume less electricity compared to air conditions, making them cost-effective. Also, the purchasing price of a desert air cooler is much less.
  3. Desert air coolers are easy to maintain in the long run.
  4. Desert air coolers are eco-friendly, They do not cause harm to the environment as they do not use cooling agents like the Freon in the ACs.
  5. Compared to personal air coolers, the cooling effect of desert air coolers is not limited to bed sizes, instead they serve the entire room.

How to choose a Desert air cooler?

Please consider reviewing the following points before buying a desert air cooler.

  1. Size: Desert air coolers come in various sizes, the capacity being denoted in Litres (L). Analyse the space area where you wish to install the desert air cooler and select the size accordingly. For instance, for a room with a 200-square-foot area, consider choosing a desert air cooler of 40-50 L capacity. On the other hand, 25 L capacity would work fine for small rooms of 100 – 150 Sq-foot area.
  2. Castor Wheels: In most uses, desert air coolers are fixed outside windows, yet modern deserts come with castor wheels to help them move from one location to another when installed indoors.
  3. Cooling pads: Choose desert air coolers with honeycomb pads. Honeycomb pads are known for providing better evaporation and durability in the long run.
  4. Air Flow: Ensure to check the air delivery volume of the desert air cooler before buying one. A flow is expressed in CFM (Cubic feet per minute). The more the CFM, the larger the area that is covered.

How to calculate the required CFM?

Use the formula to calculate the minimum required CFM of airflow.

CFM of air flow = Area of room x ceiling height/2

It implies, that for a room with an area of 200 sq-foot and 10 feet height, the CFM should be 200x 10/2=1000 

5. Air throw distance: Ensure the air throw distance covers the longest dimension of your room by 1.5 to 2 times. This would ensure efficient cooling of the room.

6. Warranty Coverage: Check the warranty details and enquire about the applicable conditions, if any, when buying a desert air cooler.
