What Is An Evaporative Cooler?

Evaporative Coolers, also known by the names swamp coolers or open space coolers, are an energy-saving and affordable way to cool your air. Evaporative cooling is often considered a cheaper alternative to traditional air conditioning, which has high costs of installation and ongoing maintenance. Evaporative coolers are more natural than air conditioning. They use water to produce cool, fresh air.

To simplify, water vapor formation requires liquid water to absorb heat. Also known as the Latent Heating of Evaporation. This heat is released into the air when the water vapor becomes vapor. This is how you get cooler air. Cooling devices called Evaporative Coolers make use of this cooling phenomenon to produce cool, fresh air that can be spread throughout buildings, open areas, and to the people who need it.

How Does An Evaporative Cooler Take Advantage Of The Benefits Of Evaporative Cooling?

Evaporative Coolers use high-efficiency cooling media, called Evaporative Cooler Pads to accelerate the evaporation. The cooling unit uses water to circulate the cooling pads, keeping them constantly wet. Air is drawn in through the cooling pad, and the water on the cooling medium is evaporated to cool the air.

  1. The water pump circulates the water from the water reservoir to the top, keeping it hydrated all the time.
  2. Running fan draws outside warm air into the cooler through the cooling media.
  3. Water evaporates when the air passes the wet medium. It is because of this water evaporation that the cooler cools down.

What Cooling Effects Can Evaporative Coolers Deliver?

 Naturally, the cooling effect of evaporative coolers will be affected by two factors: the outside relative humidity.

Evaporative coolers provide better cooling performance in dry environments where the relative humidity is not too high. This is because the cooler air is, the more water the cooling media can remove from the atmosphere. Also, the less water that evaporates in the atmosphere, the cooler it will be. Evaporative Coolers work best in hotter or drier climates. Evaporative coolers can supply air as much as 10 degrees Celsius cooler than outside temperatures in the ideal conditions. For example, an Evaporative Cooler could cool 38 degrees Celsius outside air temperatures to 28 degrees Celsius under ideal atmospheric conditions.

Where Is Evaporative Cooling Usually Used?

Evaporative coolers can be used to cool semi-enclosed buildings or open areas. They are most commonly used in industries such as factories and warehouses. They are also found in outdoor commercial spaces like semi-outdoor shops, office complexes, or other areas. It is possible to find smaller Evaporative coolers in residential areas.

Waterline Cooling and Evaporative Coolers were designed specifically to meet industrial-grade standards.

What Is The Difference Between Evaporative Coolers And Air Conditioning Systems,

Evaporative coolers cannot replace HVAC and refrigeration systems. Air conditioning is a combination of coolant and refrigerant that produces chilled air at very low temperatures. While it may be able to cool the air, it still requires energy. For industrial applications, the cost of chilling a whole factory or warehouse with Air conditioning is prohibitive.

To give an example of cost comparison, an evaporative cooling solution costs approximately 50% less than an HVAC system to cool the same area. Evaporative cooling systems are preferred by many factory decision-makers due to their low cost and ability to provide comfortable work environments at a fraction compared to air conditioning.
