Know How The Main Evaporative Cooler Parts Work


Visitors: 262

Have you ever wondered how your air cooler operates or what it is made up of? The swamp cooler is not only easy to operate, but it is also made up of simple parts that work in a natural manner. The main evaporative cooler parts consist of a blower motor, evaporative pads, recirculation water pump, blower, screen, and float valve.

Workings Of Cooler Parts

We often opt for air coolers to cut down electricity bill. The blower motor is energy efficient since it just has to circulate the air instead of compressing it as in air conditioners. It is best to buy an air cooler that has 2-3 speed blower motor with appropriate blower regulator. The blower motor generally has 1/3 or ¾ horsepower.

The direct evaporative coolers are categorized by the style of pad that is used. There are two basic types of pads used in an evaporative cooler – fiber pads and rigid-sheet pads. The fiber pads are very common and are made up of shredded aspen that are placed in nets made of plastic. The thickness of the pads varies from 1-2 inches. For thinner pads, double pads should be placed in the pad frame to improve the effectiveness of saturation. Rigid-sheet pads consist of a pack of corrugated sheets through which air passes and are 8 - 12 inches in thickness. These pads cost more than the aspen pads and lasts for a longer time.

Operations Of Various Air Cooler Parts

Water is constantly supplied to moisten the pads inside a cooler. The excess water collects in a sump below the pads. The recirculating water pump is used to send back this water to the pads for constantly keeping it wet.

The float valve controls the level of water in the sump that is accumulated at the bottom of the air cooler. When the level falls below normal, they add water to keep the level constant. A powerful fan is used to draw air from outside into the air cooler through the wet pads. This process of making the air pass through water molecules cools the air temperature. The fan then acts as a blower and blows out the cooled air into the room where it is placed.

These air cooler parts ensure the proper functioning of the system so as to provide you with an economic and healthy way of constantly filling your room with cool and fresh air.
