Desert Air Cooler

Desert air coolers are a type of air coolers that are designed to work effectively in hot and dry climates. They are also known as evaporative coolers or swamp coolers, as they use the evaporation principle to lower the air temperature. Desert air coolers are becoming more popular as they offer a natural and eco-friendly way of cooling your space without using any refrigerants or chemicals. However, many people have misconceptions about desert air coolers, such as being noisy, consuming a lot of water, or causing health problems. This blog will explain everything you need to know about desert air coolers, their benefits, limitations, and considerations.

WHAT IS DESERT AIR COOLER?

A desert cooler is a device that cools the air by evaporating water. It consists of a fan, a water tank, and a wet wick, pad, or filter. The fan draws in hot and dry air from the outside and passes it through the wet wick, pad, or filter. As the air passes through, some of the water evaporates and absorbs heat from the air, lowering its temperature. The cooled and moistened air is then blown out into the room, creating a refreshing breeze.

The desert air cooler meaning is derived from the fact that it works best in desert-like conditions, where the relative humidity is low and the temperature is high. The lower the humidity, the more water can evaporate, and the more cooling effect can be achieved. The desert air cooler can lower the temperature of the air by up to 15°C, depending on the ambient conditions.

BENEFITS OF DESERT AIR COOLERS

Desert air coolers have several benefits, as they can provide effective and efficient cooling for your space. Here are some of the advantages of desert air coolers:

Effective cooling in hot and dry climates: Desert air coolers are ideal for regions where the temperature is high and the humidity is low, such as deserts, semi-arid areas, or tropical zones. They can cool the air more than other air coolers, such as personal or tower air coolers, which are more suitable for moderate climates. Desert air coolers can also create a natural and pleasant airflow, which can make you feel more comfortable and refreshed.
High air delivery and a big water tank: Desert air coolers have a high air delivery rate, which means they can circulate a large volume of air in a short time. This can cool a large area quickly and effectively. Desert air coolers also have a big water tank, which can hold up to 50 liters of water or more. This can ensure a sustained and consistent cooling performance, without the need to refill the water frequently.
Ease of movement with castor wheels: Some desert air coolers come with castor wheels, which can provide ease of movement and portability. You can move the desert air cooler from one room to another, or from indoors to outdoors, depending on your needs and preferences. You can also adjust the direction and speed of the fan, as well as the water level and flow, using the knobs or remote control.
Cheaper than other cooling alternatives: Desert Air Coolers are efficient at cooling and are generally cheaper than other cooling alternatives such as an air conditioner. There are a variety of air cooler under 10000 rupee and air conditioners, on the other hand, are usually costlier. However, it is also important to note that air coolers are different from air conditioners, and in extreme temperatures, air coolers may not provide the best cooling. However, in medium summer desert coolers are good to go and a cheaper alternative than other devices.

LIMITATIONS AND CONSIDERATIONS

Desert air coolers are not perfect, and they have some limitations and drawbacks that you should be aware of. Here are some of the challenges and concerns of using desert air coolers:

Larger size compared to personal air coolers: Desert air coolers are bigger and heavier than personal air coolers, which are smaller and lighter. This means that desert air coolers take up more space and may not fit in some rooms or places. Desert air coolers may also be more difficult to store or transport, especially if they do not have castor wheels or handles.
More suitable for commercial or industrial settings: Desert air coolers are more suitable for cooling large spaces, such as halls, warehouses, factories, or outdoor areas. They may not be very effective or efficient for cooling small spaces, such as bedrooms, living rooms, or offices. Desert air coolers may also be too noisy or powerful for some residential or personal settings, as they can create a strong and loud airflow.
Require more maintenance than personal air coolers: Desert air coolers require more maintenance and cleaning than personal air coolers, as they use more water and have more components. You need to change the water in the tank regularly, as stale or dirty water can cause bad smells, bacteria growth, or mineral deposits. You also need to clean the wick, pad, or filter, as they can accumulate dust, dirt, or mold. You also need to check the fan, motor, and electrical parts for any damage or malfunction.
Tend to be a lot more expensive than personal air coolers: Desert air coolers tend to be a lot more expensive than personal air coolers, as they have a higher capacity, performance, and quality. Desert air coolers can cost anywhere from 10,000 to 20,000 rupees or more, depending on the brand, model, and features. Personal air coolers can cost anywhere from 3,000 to 10,000 rupees or less, depending on the same factors.

CONCLUSION

Desert air coolers also known as evaporative coolers are a type of air coolers that are designed to work effectively in hot and dry climates. They use the principle of evaporation to lower the air temperature, and they have a high air delivery and a big water tank for sustained and effective cooling. Some models also come with castor wheels, providing ease of movement. However, desert air coolers have limitations and drawbacks, such as their larger size, more suitability for commercial or industrial settings, more maintenance requirements, and higher prices. Some other types of air coolers available in the market are- room air coolers, personal coolers, tower coolers, and window coolers.

Industrial air cooler and commercial air coolers are similar to desert coolers but are intended for larger spaces and industrial settings, offering powerful cooling performance.

When using a desert air cooler or any evaporative cooler, regular maintenance tips are crucial to ensure optimal performance and longevity for hot and dry climate cooling.

The difference between a desert cooler and an air cooler is mainly based on the cooler's size, capacity, and performance, as well as the climate and space where it is used. Desert coolers are large air coolers, more powerful, and more effective than personal air coolers but are also more expensive, noisy, and maintenance-intensive. Personal air coolers or portable air coolers are smaller, less powerful, and less effective than desert air coolers, but they are also cheaper, quieter, and easier to use. We have written a blog about different types of air coolers, give it a read to know their benefits, differences and more.

The answer to the question ‘how desert cooler throws cool air’ is that it pulls hot, dry air and passes it through a wet wick, pad, or filter, where some of the water evaporates and absorbs heat from the air, lowering its temperature. The cooled and moistened air is thrown out into the room, creating a refreshing breeze for effective air cooling.

We hope this blog has helped you understand what a desert air cooler is, its energy efficiency, its benefits, limitations, and considerations. If you are looking for a desert air cooler, you should consider factors such as the size, power, noise, and features of the cooler, as well as your budget and preferences, and make a considerable choice.
