Types Of Evaporative Air Cooler

Indirect evaporative air coolers.

Types of evaporative air cooler.

There are several kinds of evaporative air coolers. An evaporative air cooler is a type of air conditioner that works by harnessing the power of evaporation to cool air temperatures when water evaporates it turns from liquid to gas as it does so the highest energy particles leave the water first and this leads to a drop in temperature. According to some manufacturers pads can last for up to a year while others boast a long life of seven years but this does depend on water quality and local weather conditions. 3 kinds of evaporative air coolers that will save you money.

Some fixed units blow air straight into the building while others use duct systems to transfer air to multiple locations. Unlike central air conditioning systems that recirculate the same air evaporative coolers provide a steady stream of fresh air into the house. Evaporative cooling differs from typical air conditioning systems which use vapor compression or absorption refrigeration cycles. The fan distributes it around the room for even cooling.

The air that comes out of the vents is cooler and more humid. How much the unit cools air depends on ambient temperature and relative humidity. An evaporative cooler also swamp cooler swamp box desert cooler and wet air cooler is a device that cools air through the evaporation of water. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate.

Swamp coolers are most effective when it is hot and dry. Evaporative coolers that are installed with up ducts will need additional attic ventilation. Apart from regular maintenance evaporative cooler pads will need to be serviced. For a start they are generally not portable.

Direct evaporative air cooler. This is why a moist cloth on your forehead feels good on a hot day it s actually helping to lower. An evaporative cooler comes with a fan and a wet cooling pad which the fan uses to gather warm air inside the appliance before sending to the soaked water. With direct evaporative cooling process a blower forces air through a permeable and water soaked pad wherein the air is filtered and cooled as well as humidified.

In the process the air gets cooler. The warm air causes water on the media to evaporate. Contrary to what is known about all air coolers the indirect evaporative air coolers do not improve the humidity of the space it is cooling. All types of air conditioning require systematic checks.

But that s generally where the similarities end because the biggest difference between these two types of appliances is that evaporative cooling cools the air through evaporating water. Most whole house evaporative coolers are mounted on the roof and blow air downward while others are mounted through windows or walls and blow air in from the side. Different types of evaporative coolers 1. Evaporative coolers are typically distinguished by where they are installed and the type of pads they use.

Some are portable and others must be fixed somewhere to the wall.
