Types Of Evaporative Air Cooler

Indirect evaporative air coolers.

Types of evaporative air cooler.

How much the unit cools air depends on ambient temperature and relative humidity. 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. 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. The indirect evaporative air coolers are quite different from swamp coolers.

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. Different types of evaporative coolers 1. 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. Some are portable and others must be fixed somewhere to the wall.

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. 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. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat in order to evaporate.

This is why a moist cloth on your forehead feels good on a hot day it s actually helping to lower. When operating an evaporative cooler windows are opened part way to allow warm indoor air to escape as it is replaced by cooled air. Apart from regular maintenance evaporative cooler pads will need to be serviced. 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. Unlike central air conditioning systems that recirculate the same air evaporative coolers provide a steady stream of fresh air into the house. Evaporative coolers are typically distinguished by where they are installed and the type of pads they use. Some fixed units blow air straight into the building while others use duct systems to transfer air to multiple locations.

The warm air causes water on the media to evaporate. The air that comes out of the vents is cooler and more humid. Swamp coolers are most effective when it is hot and dry. Direct evaporative air cooler.

3 kinds of evaporative air coolers that will save you money. 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. Evaporative coolers that are installed with up ducts will need additional attic ventilation. 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.

For a start they are generally not portable.
