Evaporative cooling systems are used in many homes, especially in low humidity level areas. This type of cooler comes in a box shape and air passes through one or more porous surfaces.
Air from outside is pulled into the home with the help of fan inside the unit. A material that absorbs water is fixed to each porous side of the cooler which produces cool air. A small pump is fixed in the cooler that lifts water stored in a pan at the bottom and circulated to the top of each side.
You will realize that the evaporative cooling system is working efficiently if you get consistent cool air at all times. This is possible by keeping the pad appropriately damp and not too soaked. The most effective cooling is created by right amount of damping. In order to dampen the pads properly, it is necessary to adjust the amount of water moved by the water pump.

Evaporative cooling installation
It is recommended to get your evaporative cooling system installed by professionals. They will be capable to tell you correctly how to adjust the airflow and control the weather inside your home. It is necessary to achieve the right air balance. The same amount of air pumped into your home must also flow out to limit humidity and ensure the cooler functions optimally.
Evaporative cooling installation involves installing ducts in open windows or in each room when the cooler is in use. By doing this, you will be able to obtain a balanced air flow. The pressure in the room must be such that the door closes gently and quietly. This can be achieved by leaving a window partially open. If the door bangs shut, window should be opened wider as the exhaust is too little. If the window is open too far, the door will not move at all.
Buying the right sized cooler for your home
Before buying the evaporative cooling installation system matching your requirements, it is important to determine the amount of CFM or Cubic Feet of air per Minute that can be pumped by the unit. CFM number is usually printed in the owner’s manual or on the evaporative cooler. If you cannot find it, it is possible to calculate the same with a simple formula.
CFM Formula – Average ceiling height x square foot of your home (divided by) 2
Caring for the evaporative cooler after installation
It is not enough to focus on evaporative cooling installation and leave it to work on its own. It is necessary to care for your cooler servicing at least twice a year and preferably in mid-summer and just before cooling season. It is possible to improve efficiency of the equipment and extend the life through regular maintenance.
Maintenance requires diligently following some major steps:-
- Clean pad frames regularly and change pads as and when needed. Scale can be scraped away using a wire brush. Use a cooler protection to paint surfaces.
- Water distribution system that include water distribution tubes, pump impeller and pump screen must be cleaned periodically. SAW 20 motor oil should be used to keep the pump impeller lubricated. If you find any cracked tubing, it should be immediately replaced.
- Electrical switches and wiring must be inspected for worn out insulation or poor connections. Belts must be checked for wear and cracks and worn out parts must either be repaired or replaced.
- Water must dampen the cooler pads sufficiently. Cooler’s efficiency may be greatly reduced through dry spots caused by too little water.
Evaporative cooler installation and efficiency
As you install the evaporative cooling system, it is important to add in the cooler thermostats. These thermostats can be purchased from any hardware store. When the air reaches the required temperature, the thermostat turns off the cooler and keeps it running efficiently for a long time. In case your cooler does not have thermostats, it is important to keep cooler pads saturated by turning on the fan after allowing the pump to run for a few minutes.
