Desert Cooler Cooling Better on Hot Days Desert Cooler Cooling Better on Hot Days

A desert cooler is a great way to cool yourself amidst heat as they are known for being suitable for hot and dry climates. If the humidity level in your area is below 50%, a desert cooler can work as the most effective and efficient cooling solution.

Desert coolers are not only practical and efficient, but they also add a refreshing and natural element to any living space. In this blog, we will explain why desert coolers are more effective on hot days. 


Why is it called a Desert Cooler?


As the name suggests, a desert cooler is called so due to its nature. It is suited to hot and dry ‘desert-like’ climates, where the air is hot and the humidity is low. The name ‘desert cooler’ is also used to distinguish it from other types of cooling devices, such as air conditioners, which use refrigerants to cool the air, and are not as effective in dry climates. The desert cooler working principle is based on the evaporation of water, which is why it is also known as an evaporative cooler.


How does a Desert Cooler work?


Wondering how a desert cooler really functions? The basic mechanism of a desert cooler involves the following steps.


  1. The hot air is drawn into the cooler through a fan and is absorbed in a set of cooling pads inside the unit. These cooling pads are soaked in water. 
  2. Then the hot air passes over the cooling pads. When this hot air meets the water in the pads, the water evaporates. In this process, it absorbs heat from the air and cools it down. 
  3. The cooled air is then circulated back into the room through a fan. 
  4. The water in the cooler’s tank is continuously circulated over the cooling pads, keeping them moist and ensuring that the cooling process is maintained.

Why is a Desert Cooler More Effective in the Summer Months?


A desert cooler works on the simple principle of evaporative cooling. Evaporation is inversely proportional to humidity, so the lesser the humidity and higher the temperature, the faster the evaporation. So on a hot dry day, the humidity is less. So, water present inside the desert cooler evaporates more, thereby cooling the surroundings more. 


Advantages of a Desert Cooler that make it a must-have in the Summers


Wondering why a desert cooler is best suited for you in the summer? Here are some of the many benefits of desert coolers.


  1. Unlike air conditioners, which require a closed room and use refrigerants to cool the air, desert coolers use water and a fan to cool the air reducing harmful toxins in the environment.  
  2. By using water to cool the air, a desert cooler can effectively lower the temperature in hot and dry climates, while also increasing the humidity levels, which is best suited for you if you’re in a dry and hot region. 
  3. Desert coolers can be beneficial for those with dry skin or respiratory issues since it increases humidity in the environment. 
  4. Desert coolers are more energy-efficient and eco-friendly than traditional air conditioning systems, making them a popular choice for those looking for a more sustainable and cost-effective cooling solution.

1. How much temperature is reduced by a desert cooler?

A desert cooler can reduce the temperature in a room by as much as 15 to 20 degrees Celsius, depending on several factors such as the size of the room, the ambient temperature, and the efficiency of the cooler. 

2. Why do desert coolers not work on a rainy day?

On a rainy day, the air is already humid, which means that the moisture in the air is high, making it more difficult for the water on the cooling pads to evaporate. This can make the cooling process less effective for a desert cooler.
