Air Flow from Evaporative Cooler

Evaporative Cooler Air Flow

An evaporative cooler is basically a large fan with water-moistened pads in front of it.

The fan sucks the warm air from outside through the moistened pads and blows the resulting cooled air through your office or home.Water is supplies to the pads through small “supply” lines. This water then soaks the pads and drizzles through them to collect at the bottom of the cooler. A small water pump then circulates the water back to the top and the process continues
As water is being continually lost through evaporation, it is essential that you have a good float valve (similar to the one used in toilets) that adds water to the evaporative cooler when levels start to get low.
A large fan then extracts air through the pads and evaporation cools the temperature of the air, which is then blown through your home cooling it.

TIP – To get you evaporative cooler to work effectively, the cooled air must be allowed to leave you home. So by strategically choosing which windows you leave open, you can direct the flow of cool air through your home or other building.

Why an Air cooler (swamp cooler or spot coolers)?

Why an Air Cooler? (Also Known as a Swamp Coolers or Spot Coolers)

These free standing Portable Air Coolers (Evaporative Swamp Cooler) work by endothermic reaction (a reaction that consumes heat). They use a fan to draw in hot, dry air through a wetted material. As the hot dry air is pulled through the wetted material, the dry air absorbs moisture through evaporation which absorbs heat and the air is cooled and becomes more humid. The DRYER the input air, the more effective it is. If the air being drawn through the pads is humid (Above 58%) there will be no cooling effect because humid air will not absorb moisture through evaporation because it is already wet.

These Evaporative Portable Air Coolers (Evaporative Swamp Coolers) , Humidifiers, and Fan are versatile, lightweight and economical way to cool your personal air by cooling the air that goes through the unit down by  10°F to 15°F cooler than the ambient air temperature. The Coolers easily roll from room to room for use anywhere in your house or office.
 
Unlike a typical fan, which simply blows the ambient air around with no temperature change at all, the free standing Portable Air Cooler (Evaporative Swamp Cooler) can cool the ambient air that goes through the unit down by 10°F to 15°F and adding Ice for even extra air cooling!

In no way does free standing Portable Air Coolers (Evaporative Swamp Cooler) do the work of an air conditioner. It WILL NOT dehumidify the air nor will it cool a room by reducing the ambient air temperature of a room like an air conditioner. They simply are a better air blower than a typical fan and reduce the air temperature through the unit down 10 °F to 15 °F. They are for personal cooling!

The free standing Portable Air Cooling  (Evaporative Swamp Cooler) is environmentally friendly because they do not use freon. These Portable Air Coolers (Evaporative Swamp Cooler) have casters which allow it to be easily moved from room to room with no heavy lifting and uses 100 Watts!.

These free standing Air Coolers (Evaporative Swamp Cooler) are great for use in small apartments, condos, offices , RV's or any area that an air conditioner can not be used or can not reach.

Amongst all air cooling technologies, evaporative air cooling is the only method of natural cooling of Air. Evaporative air cooling works on the principle of 'heat absorption' by moisture/water evaporation. The evaporative air cooling draws exterior air into special cooling pads soaked with water where the air is cooled by evaporation and then circulated into the space to be cooled. Evaporative air cooling is the most cost effective method of air cooling.
