Types Of Evaporative Air Cooler

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.

Types of evaporative air cooler.

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. All types of air conditioning require systematic checks. Different types of evaporative coolers 1. 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.

There are several kinds of evaporative air coolers. Evaporative coolers cost about one half as much to install as central air conditioners and use about one quarter as. Direct evaporative air cooler. The fan distributes it around the room for even cooling.

Evaporative cooling differs from typical air conditioning systems which use vapor compression or absorption refrigeration cycles. 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. Some fixed units blow air straight into the building while others use duct systems to transfer air to multiple locations. Apart from regular maintenance evaporative cooler pads will need to be serviced.

The indirect evaporative air coolers are quite different from swamp coolers. Evaporative coolers that are installed with up ducts will need additional attic ventilation. 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. 3 kinds of evaporative air coolers that will save you money.

When operating an evaporative cooler windows are opened part way to allow warm indoor air to escape as it is replaced by cooled air. For a start they are generally not portable. Unlike central air conditioning systems that recirculate the same air evaporative coolers provide a steady stream of fresh air into the house. 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.

Swamp coolers are most effective when it is hot and dry. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate. 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. Some are portable and others must be fixed somewhere to the wall.

Evaporative coolers are typically distinguished by where they are installed and the type of pads they use. The warm air causes water on the media to evaporate. Indirect evaporative air coolers. 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.
