How Do Evaporative Cooling Systems Work

Factory heating and cooling companies are now offering evaporative cooling systems as a cost effective and environmentally friendly alternative to refrigerant-based cooling systems.

While both factory cooling systems are designed to maintain comfortable room temperatures, evaporative cooling systems are completely differently to a normal air conditioner, and far more efficient.

Evaporative cooling systems, sometimes called swamp coolers, work by utilizing the natural process of evaporation to provide cooler temperatures.

These factory cooling systems work by pulling the outside air through mildew resistant filters that are moistened with water, and then dispersing the cooler air with a large fan or blower.

These systems work best in areas that are hot, but do not have high humidity levels since this could cause the air to be too wet inside the rooms that are being cooled.

Evaporative cooling systems differ from typical air conditioners in other ways as well.

They do not require the use of environmentally unfriendly refrigerants, as they rely on the outside air to function. Refrigerants were once common in industrial cooling processes but have been falling out of fashion in recent years as businesses strive to reduce both emissions and costs.

As refrigerants require an industrial process to produce, transport and manufacture into air conditioning units, it has made financial sense for the industry to conceive, design and manufacture units that do not rely on them.

The air circulated by an air conditioner is recycled air from the rooms passed through a power-hungry refrigeration unit, but the air from an evaporative cooler is constantly being refreshed from the air outside.

Another difference between these two types of units is that the air from an evaporative cooling system can be directed into certain areas by simply opening windows or doors. When windows are left open, it allows hot air to be forced out by cooler air being distributed by the evaporative cooler.

Evaporative cooling systems are far cheaper to install than traditional air conditioners. While an air conditioner requires expensive ductwork to properly distribute cooler air, an evaporative cooling system can be installed without ducts.

The air is blown into a central area, and then directed to other rooms by opening or closing doors, which creates an unending supply of fresh air to all rooms. This efficiency is welcomed by the user who finds that temperature control in working areas can be maintained by simple actions.

Evaporative coolers can also be installed much like a window air conditioning unit for smaller rooms, making them flexible and easy to use in spaces that might have been otherwise awkward to condition.

Using evaporative cooler technology in a factory setting can be a very cost effective choice. From lower installation costs, the lack of refrigerant, and a 75% decrease in energy usage, evaporative cooling systems are an excellent choice for warmer, less humid climates.
