Cutting costs: About evaporative cooling systems

Posted on Jun 13, 2017

Oftentimes, about 40 percent of the energy used in commercial buildings can be traced back to the HVAC systems. So it’s no wonder that when building owners look to cut costs, they look to these systems. But before you completely shut off your air conditioning this summer in an attempt to save a few dollars, there’s a more effective way to save money: evaporative cooling systems.

These systems can be relatively inexpensive to purchase and can use less energy than other forms of cooling.

What is it?
Evaporative cooling technology cools air through the evaporation of water. These are different from traditional systems, which use vapor-compression or absorption refrigeration cycles.

There are direct, indirect and hybrid versions of the system available.

Direct: In direct evaporative cooling systems, outside air is mixed with hot return air from the building to achieve the desired supply temperature. Direct systems work well in where there are large heat-load removal needs.

Indirect: Indirect systems keep moisture separate from the application’s airstream, and takes advantage of the properties of evaporation, as well as the difference between dry and wet bulb temperatures.
