Evaporative coolers can be used in hot and dry regions as an alternative to traditional refrigerant air conditioning units. Although they aren’t as common as package units and split systems, adjusters should be familiar with this type if they deal with claims in areas that can use evaporative cools.

What Is Evaporative Cooling?

Before we can get into the details of evaporative cooling, it is important that you understand the basic principles of evaporative cooling. Evaporative cooling begins with the loss of water or other liquids into the air. The liquid becomes a gas and absorbs heat. This reduces the temperature in the air.

Evaporative cooling is a concept that has been used for thousands of years. This method was used by the ancient Egyptians to cool their homes. They soaked the fabric in water and hung it over the doors. The fabric absorbed moisture as the air moved through it.

Evaporative Coolers: How Do They Work?

This process is used to cool a space with a portable evaporative cooler. A direct evaporative cooling system is used in residential properties. This type of system uses a pump to circulate water from a reservoir and saturate the cooling pad. The fan pulls air in from the outside through the damp pad and initiates the evaporation process. The cool, humid air then gets distributed to your home.

There Are Three Types Of Residential Evaporative Cools That You Can Choose From:

Portable Coolers – These portable evaporative cooler are small enough to cool a small area. These coolers do not require professional installation. Many come with wheels so they can be moved easily from one room to the next.

Side Draft – These units are designed to blow air from the unit’s side directly into your home. This type of evaporative cooler is installed through the wall or in the window. These coolers can only cool one room, but they can cool a larger area or room than a portable cooler.

Down Draft – These units can be installed on the roof of a house and provide cooling through the use of a duct system. These units are most costly to install and can be challenging to maintain.

Are Evaporative Coolers Useful?

The air must be sufficiently dry to allow the evaporation process of cooling to work effectively. Evaporative coolers can only be used in areas with relative humidity below 60%. Evaporative coolers are not effective if the relative humidity exceeds 60%. At best, they can only reduce the temperature by 10 degrees. Even in dry climates, the humidity will rise even when it rains. These periods of high humidity should be avoided by an evaporative cooler

Differences Between Evaporative Coolers & Traditional Air Conditioning Systems

Air conditioning systems are made up of a coil that is filled with refrigerant. It transfers heat and cools the space. This cooling system uses a closed cooling process in which the room’s air is circulated back through the cooling process. The system’s efficiency will be reduced if the air is allowed to escape.

An evaporative cooler is a cooler that uses refrigerant instead. It uses a pump to circulate the water and a fan to pull the air through the pads. This humidifies dry air, and so must be ventilated. Although evaporative coolers don’t always require ductwork to direct airflow, they must use it when they do. This is to allow for greater airflow from the cooler.

Common Evaporative Cooler Issues

Evaporative coolers require frequent maintenance. To avoid any air quality problems or odors, the cooling pads must be replaced or cleaned regularly. If the evaporative cooler is running continuously, this should be done at least once per month. The cooler can also become clogged with sediment and minerals. To keep the cooler running year after year, it must be drained and cleaned out at least once per year. This can be tedious, especially if the system is installed on the roof.
