What Makes Desert Coolers More Efficient During Summers?

Desert coolers are the preferred air coolers during summer for Indian conditions. Why this is so will become quite evident when one looks at its superior mechanism for cooling. There are some cool scientific principles behind a desert cooler. Let’s know more about desert coolers and why it’s more efficient during summers. 

How Does a Desert Cooler work? 

A desert cooler works on the principle of evaporative cooling, where water evaporation lowers the air temperature. The system pulls in hot outdoor air and passes it through water-soaked cooling pads. As the warm air moves across these pads, the water evaporates and absorbs heat from the air, which makes it cooler before it circulates into the room. 

Here’s how the process works: 

  • The water pump keeps the cooling pads continuously wet
  • A fan or blower draws hot air from outside
  • The hot air passes through the wet cooling pads
  • Water evaporation removes heat from the air
  • The fan pushes the cooled air into the room 

Desert coolers perform best in hot and dry climates, where faster evaporation helps achieve more effective cooling. 

Why is it called a Desert Cooler? 

A desert cooler gets its name from the type of climate it works best in. These coolers are designed for hot and dry weather conditions like desert regions, where humidity levels are low. Unlike air conditioners that use refrigerants for cooling, desert coolers work through water evaporation. As warm air passes through water-soaked cooling pads, the evaporation process lower the air temperature. Due to this evaporative cooling method, desert coolers are also known as evaporative coolers. 

Why Does a Desert Cooler Perform Better on a Hot Day? 

A desert cooler performs more effectively on hot and dry days because the cooling process depends on water evaporation. When the temperature is high and humidity levels are low, water evaporates faster from the cooling pads. This faster evaporation absorbs more heat from the air, and this results in cooler airflow inside the room. In humid weather, the air already contains more moisture, which slows down the evaporation process and reduces cooling efficiency. 

Advantages of a Desert Cooler That Make It a Must-Have in Summers 

  • Consumes less electricity compared to air conditioners
  • Delivers fresh airflow by continuously circulating outdoor air
  • Simple installation without complex setup requirements
  • Suitable for large rooms, balconies and semi-open spaces
  • Uses water-based cooling instead of refrigerants
  • Easy to move in case of portable desert cooler models
  • Lower maintenance and operating costs for daily summer use 

Tips to Maximize Cooling from Your Desert Cooler 

Here’s a few tips to make the best out of your desert cooler: 

  • Place the cooler near a window so it draws in fresh hot air for better evaporation 
  • Keep a door or window slightly open to allow humid air to move out of the room  
  • Keep an adequate water level in the tank for steady cooling performance 
  • Clean the cooling pads regularly to maintain proper airflow and cooling efficiency 
  • Add ice to the water tank during peak summer afternoons for a temporary cooling boost  

Why Choose Voltas Desert Coolers This Summer?

Volta's desert coolers have honeycomb pads on all three sides. This provides a long-lasting cooling effect.  

  • The JetMax series of Desert Coolers have honeycomb pads to provide ultra-cooling during the summers. 
  • Victor series desert coolers of Voltas have extra-large blowers. With blowers that can be up to 46 cm in diameter, the desert coolers have a better air throw than most air coolers. Thus, the cool air will reach every corner. This will increase the efficacy of cooling even if the room is large, making it perfect for the drawing room and the living room.
  • The oscillating swing function in all Volta's desert coolers will ensure that everyone will get their share of cool air. 
  • Some of the Voltas models have a pre-soak feature. With the pre-soak feature, you will be able to moisten the cooling medium before turning on the blower. This will increase the cooling effect dramatically. 
  • A few models have an ice chamber to increase the effect of cooling. 

Volta's desert coolers provide water tanks with a holding capacity of up to 90 litres of water. Most air coolers consume a lot of water which can be quite irritating. The eco-cool mode in the Voltas Mega series will help in the efficient use of water. Once the water tank has been filled, it will last the whole night, ensuring that you have a comfortable sleep.  

Voltas also come with a trolley so that you can move it to the desired place without any hassles. There are remote-controlled desert coolers which makes their operation super easy. Since you get desert coolers that can work on inverters also, you need not worry about power cuts. 

FAQs 

What is the difference between a desert cooler and a regular cooler? 

A desert cooler is larger in size and designed for bigger spaces with strong airflow and higher water tank capacity. It works best in hot and dry climates. A regular air cooler is usually compact, suitable for smaller rooms and provides moderate cooling for everyday indoor use. 

What are the disadvantages of desert coolers? 

Desert coolers are less effective in humid weather because slower evaporation reduces cooling performance. They also need regular water refilling, periodic cleaning of cooling pads and proper ventilation for efficient operation.
