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.

How Do Eco-friendly Evaporative Air Coolers Work?

How Do Eco-friendly Evaporative Air Coolers Work?

  

AS The temperature of the remaining water drops , water is evaporated by the moving air.  Heat and energy is carried away by the faster moving molecules as water in the Air Cooler  evaporates.when the water evaporates the air near the surface increases its relative humidity and would slow down the evaporation if it was not blown away and replaced with air with a low relative humidity. The wind from the Evaporative cooler  fan increases evaporation and the rate the energy leaves the liquid water.

Temperature is a measure of the energy in the water.Since the energy in the remaining water is dropping so too is the temperature of the remaining water. The same thing happens when you lick the back of your hand and blow on it. Top 7 Reasons to Purchase an Air Cooler Healthy life style Some types of air coolers, provide comfort to people with allergies and rest.It feels cool. This is how an evaporative cooler works. Water is pumped over porous pads where air is drawn through causing the water to evaporate and cool the air.

The result is that hot dry air is converted into cool moist air that is blown into a house for cooling. The process works best when there is a good flow of air and the relative humidity of the incoming air is below 30%. The efficiency (cooling effectiveness) goes down with an increase in the relative humidity of outside hot air.

In

many location where there is low relative humidity, one effective and inexpensive means to cool houses and businesses is with evaporative coolers. These use a fan to draw hot, dry outside air through water wetted pads where evaporation of the water cools the air. The cool moist air is then blown into the house and distributed for cooling.This experiment allows you to input the outside air relative humidity and the outside air temperature to obtain the temperature of the air that is blowing from the Air Cooler  into the house.

What  you find: For a given temperature of outside air, as the relative humidity rises the temperature drop between the outside and inside air becomes less and less.

Temperatures greater than 80 degrees in the output air to the house is usually considered too high and few people will use them when this occurs.
