Evaporative Coolers: What Are They?

Evaporative Coolers also known as Open Space Coolers or Swamp Coolers were developed to provide a low-cost and efficient method of cooling air. It is often considered a cost-effective alternative to traditional Air-Conditioning. However, it has high maintenance and operating costs. Evaporative coolers are less expensive than traditional Air Conditioning. Instead of cooling the air, they evaporate water. This is a more natural process.

The process of water evaporation requires that liquid water has a high heat capacity to absorb heat. The heat that is released into the atmosphere from the resulting vapor of water is also taken with it. It is the heat being removed that makes the air cooler. Evaporative coolers make use of this cooling phenomenon to produce cool and distributed air throughout buildings and open spaces.

How Can Evaporative Coolers Benefit From Evaporative Cooling?

Evaporative Coolers use a high-efficiency cooling material called evaporative chilling pads to help with evaporation. Water circulates around the cooler unit and the cooling pads, keeping the media moist. The cooling pads allow air to be sucked in, and the cooling media then evaporates water.

What Cooling Results Do Evaporative Coolers Provide?

The evaporative cooling phenomenon is a natural science that relies on the action of nature. The outside relative humidity (or outside temperature) will play a major role in the cooling process of evaporative.

Evaporative cooling pads provide better cooling performance in dry environments where the relative humidity does not exceed 10%. This is because the cooler the outside air, the more water that can be evaporated into the atmosphere. In addition, the more water that evaporates in the atmosphere during this process, then the cooler the resulting air will be. Evaporative Coolers can work well in hotter and dryer environments.

What Are the Common Uses of Evaporative Coolers?

Evaporative coolers are used to cool semi-enclosed structures and large open areas. These coolers are used in factories, warehouses, and workshops. They can also find use in outdoor commercial spaces, such as semi-outdoor shopping areas, office buildings, and many more. Sometimes, smaller Evaporative coolers are used in residential settings.

Waterline Cooling Evaporative coolers are designed to meet industrial-grade requirements.

How Does Evaporative Cooling Compare To Air Conditioning Systems?

Air conditioning, which is different from Evaporative Coolers does not use a combination of refrigerants to create chilled air at very low temperatures. Air conditioning can cool very low temperatures, but it also requires lots of energy. Air conditioning can also be used in industrial applications. However, most facilities cannot afford to run the cost of cooling an entire factory or warehouse.

To give you an idea about the cost-comparability, an evaporative cool system will cool an area that is the same size. On average, it costs half the cost of an HVAC system. Many factory decision makers opt for evaporative cool systems due to their cost-efficiency. This is because they provide a workplace that is as comfortable as air conditioning but at a fraction cost.

Evaporative Coolers Are All Made The Same?

There are many options for Evaporative Coolers. Some coolers are built with high-quality components, while others may be made using cheaper materials. This can reduce the product’s life span.
