What is a Desert Cooler and How Does it Actually Work?

A desert air cooler is tailor-made for hot, dry environments. Today, desert air coolers are becoming more popular as they offer a natural, eco-friendly, and energy-efficient, way of cooling your space without using any refrigerants or chemicals. Companies like Zamil AC offer desert coolers as part of their product range. They can be used both indoors and outdoors. Let’s find out in this article everything you need to know about desert air coolers.

What is a Desert Cooler?

A desert cooler, known as an evaporative cooler or swamp cooler, is a type of air-cooling device that is particularly effective in hot, dry climates. The desert cooler meaning derives from the fact that it works best in desert-like conditions, where the humidity and temperature are low. The lower the humidity, the more water can evaporate, and the more cooling effect can be achieved. The desert air cooler can lower the air temperature by up to 15°C, depending on the ambient conditions.

Key Features of a Desert Cooler

Desert air coolers should have several key features to provide effective and efficient cooling for your space. Here are some important characteristics to look for:

·      Large Water Tank: A spacious reservoir allows for longer operation without frequent refills.

·      Powerful Air Throw: Helps distribute cool air throughout the room. The cooler can cool larger spaces and reach distant corners of the room.

·      Low Power Consumption: Energy-efficient, making it an economical cooling option for hot, dry climates.

·      Water Level Indicator: Helps monitor water levels easily, preventing the cooler from running dry and potentially damaging the pump.

·      Castor wheels: Some desert air coolers come with castor wheels, which can provide ease of movement and portability.

Why Choose a Desert Cooler Over a Normal AC?

Desert coolers are ideal for hot, dry climates, offering lower operating costs due to reduced energy consumption compared to traditional ACs.

On the other hand, installation of these cooling systems requires only a basic setup and minimal modifications to the building. Moreover, the maintenance of desert coolers is simple, primarily involving regular cleaning of the cooling pads and ensuring an acceptable water supply which not only saves time but also reduces long-term maintenance costs.

How Does a Desert Cooler Work?

Desert air coolers use water evaporation to cool the air. They consist of a fan, water reservoir, and evaporative cooling pads. Hot, dry air is drawn in, passing through a wetted pad where water evaporates, absorbing heat and lowering the air temperature, which is then blown back into the room by the fan.

Common Myths About Desert Coolers

Many people have misconceptions about desert air coolers. Here are some myths about them and the truth behind them:

 Myth 1: Desert coolers are noisier than regular ACs.

Truth: Modern desert coolers are designed with low-noise fans and motors. Many models operate at noise levels below 60 decibels, which is quieter than normal conversation.

Myth 2: Desert coolers consume a lot of water.

Truth: While desert coolers do use water, the amount is modest. A typical unit might use 15-20 liters per day, which is far less than many household activities like washing clothes or showering.

Myth 3: Desert coolers cause health problems.

Truth: When properly maintained, desert coolers can improve air quality. They add moisture to dry air, which can relieve respiratory issues. Some models also include air purification features.

Myth 4: Desert coolers use a lot of energy.

Truth: Contrary to popular belief, evaporative coolers are one of the most energy-efficient options on the market. On average, a standard air conditioning unit will require 900 watts of electricity per hour, while large evaporative coolers only use about 200 watts per hour.

Frequently Asked Questions (FAQs)

Which is better AC or desert cooler?

AC is better for cooling in hot and humid climates, offering more effective temperature control. Desert coolers are more energy-efficient and cost-effective but work best in dry climates. The choice depends on climate and cooling needs.

How does a desert cooler cool the room?

The desert cooler process involves the conversion of liquid water into vapor, which absorbs heat from the surrounding air, thereby lowering the temperature.

Can we put ice in the desert cooler?

Yes, we can put ice in the desert cooler, but keep in mind that adding too much ice will slow down the evaporating process. Make sure that you add ice in a moderate amount.
