An evaporative cooler is a modern day innovative device that cools air through the evaporation of water. And, there are different from regular air conditioning systems which simply use vapor-compression o absorption refrigerator cycle. Evaporative cooling performs best by using water’s large enthalpy of vaporization.
Though heat pumps are the most energy-efficient cooling system for our local climate, many homes in the Valley are armed with these coolers. These units implement best when the outside moisture level is low.
What is an evaporative cooler?
An evaporative cooler is a simply a box-shaped application with one or more porous surfaces that enable air to pass through. A fan inside the unit pulls outside air through the sides and into the house. To produce cool air, each porous side is fitted with a pad of water-absorbing material. Water is stored in a pan at the bottom of the cooler and a small pump lifts the water to the top of each side.
Top 5 Portable Evaporative Coolers of 2018
- Honeywell CS10XE
- Luma Comfort EC45S
- Portacool Cyclone 3000
- Voltas VN D50MH 50ltr Desert Cooler With Honeycomb
- Bajaj DC2015 43 Ltrs Room Air Cooler (White)
To efficiently cool your home, each pad wishes to continue damp, but not soaked. Dampness creates the most evaporation and, therefore, the most cooling. The amount of water the pump moves may need to be adjusted from time to time to properly dampen the pads.
Adjusting the air flow
To limit humidity level, all you need is to ensure the same volume of air flows out of your home as is forced in. Climate control inside the home with an evaporative cooler simply depends on air balance.
To limit humidity, you need to make sure that the same volume of air flows out of your home as is pumped in.
You can easily attain composed air flow by connecting ducts in each room or opening windows when the cooler is in use. A window should be open just enough to allow air pressure confidential a room to gradually and silently close the door to that room.
Checking unit size
To select the right size evaporative cooler for your home, you need to regulate how many cubic feet of air per minute (CFM) the unit can pump.
If you can’t find the CFM number on your evaporative cooler or in the owner’s manual, the following formula will help you calculate it:
- Multiply the square footage of your home by the average height of the ceiling (in feet).
- Divide by two (air changes per minute).
- Example: 1,625 sq. ft. x 8 ft. (ceiling height) = 6,500 CFM/2
- Caring for your cooler
Have your cooler checked twice a year, previous to the chilling season and central through summer. Steady upkeep will help spread the life and competence of the tackle.
Before setting up the unit, also perform these simple maintenance steps. Use a wire simple wide brush to scrape away the scale. A paint surfaces with a cooler protectant. Always scrape through clean pad frames. Also, drain and flush the reservoir and scrape away and paint with protectant.
One must swap any split tubing. Oil the pump impeller with SAW 20 motor oil. It’s always a good idea to inspect electric wiring and switches for poor associates or worn protection. Inspect the belt for cracks and wear. Replace or repair worn parts.
Look for adjustable motor pins for good belt tension. Set the belt tension so that reasonable hand pressure will dampen the belt about one inch from the center.
