What Are Evaporative Coolers, And Why Should You Buy One?

Evaporative coolers are more environmentally friendly, cost-effective, and energy-efficient than air conditioners. They cool and filter the air using the natural process of air evaporation.

The system, installed in your home or workplace, will provide cool, fresh air that will act as a comfort buffer against the summer heat in South Africa.

How Does Evaporation Cool Air?

Using latent heat, natural evaporation converts water from its liquid state to water vapor or gas. As water absorbs heat to evaporate, the temperature of the air around it drops significantly.

Evaporative Coolers And How They Work

Evaporative coolers are made using the same principle. Hot, dry air is drawn outside and circulated through a water-soaked cooling pad. The water evaporates as the air passes through the pad and into the filtered air.

The energy used to power the process naturally absorbs the heat. The cool, humidified breeze circulates through the interior, removing dust, pollen, and pollutants.

The Best Option Is An Evaporative Cooler

Evaporative coolers perform best in dry climates. The more water vapor evaporates into the air as the temperature drops.

This low-cost, clean, and environmentally friendly air-cooling system is ideal for South Africa’s Karoo, Free State, North West Province, and Western and Northern Cape.

Various Types Of Evaporative Cooling

Many different types and models of portable evaporative cooler are available, but they all follow the same three principles.

Evaporative Cooling Indirect

Direct evaporative cooling, the most common and simple method, is also the most straightforward. This is accomplished using a fan to draw air through a damp, spongy pad. The cool air is then distributed to an interior space through ducts or directly.

Evaporative Cooling Via Indirect Evaporation

A heat exchange center with two air streams achieves direct evaporative cooling. One stream of air cools the core. This stream is known as evaporation. The second stream of air is drawn through and cooled by the core before being distributed to an interior.

A heat exchanger could be a collection of wet metal tubes. The tubes are filled with air. The evaporative process cools the tubes, and the air is blown out.

Outside air is drawn through the tubes’ interiors, which cools them. The air is then vented into the interior space.

Direct cooling consumes more energy and is more expensive than indirect evaporative cooling. It adds less moisture to the air, which could be beneficial. It is ideal for humid environments and other applications where humidity is undesirable. Extra moisture can promote the growth of mold spores or mites, which is harmful to people with asthma, allergies, or other respiratory issues.

Evaporative Cooling In Two Stages

Two-stage indirect cooling is the third option. The initial air is then cooled indirectly. After that, the air is cooled indirectly.

This cooling method works best in hot, dry climates. Although it is the most expensive and adds humidity to the indoor air, it provides the best cooling.

Evaporative Coolers Have Numerous Advantages

Purchase an evaporative cooler for your home or office.

Traditional air conditioning provides less comfort and benefits than evaporative coolers. Evaporative coolers can save you up to 87 percent on electricity and roughly half on installation and operating costs. You will have access to a cooling system that is quiet, non-invasive, and clean.

Evaporative coolers are simple to maintain and good for the environment. Evaporative coolers pollute less than refrigerated systems. Carbon emissions are also minimal.

You’ll breathe cleaner air in your office or home. Evaporative coolers do not recirculate air; instead, fresh air from outside replaces stale air
