Evaporative cooling uses less energy than standard refrigerant air conditioning systems to chill the air in a building or region. Evaporative Coolers (also known as Swamp Coolers) circulate air across or through an evaporative cooling material drenched in water. The pads evaporate water and chill the air. Cool air is then forced into the space, while warmer air departs through open windows or vents.
Evaporative Cooling Advantages
Swamp and evaporative cooling systems are usually less expensive to operate and purchase than regular air conditioners with refrigeration. There are numerous limits to evaporative coolers. Evaporative coolers must be able to add moisture to the air to chill it. They perform effectively in places where the external air is dry throughout the summer. Manufacturers recommend that evaporative cooling be utilized exclusively in low-humidity areas of the United States. Evaporative cooler maintenance is rather simple.
Evaporative Cooling And Ventilation
Evaporative coolers function by continually drawing in air. Evaporation is used to chill the colder air circulated by a fan. Open windows allow warmer interior air to escape. This is in contrast to how air conditioning systems work. They treat and circulate air within buildings and perform best when sealed.
An evaporative coolant will be useless in cooling a structure with few windows, doors, or vents that enable outside air to enter. A swamp or evaporative cooler cannot provide the same level of air cleansing as a high MERV filter in an air handler for a central air conditioning system. Many evaporative cooling devices use swamp cooler filters, which are less effective than those with high MERV ratings.
Adding A Water Source
A water tank is included with evaporative coolers. A bucket and hose can be used to fill portable swamp coolers. However, many units can be linked together to provide continuous water delivery.
Evaporative Cooler Dimensions
The volume of air provided by the swamp or evaporative coolers is measured in cubic feet per hour (cfm). According to Energy Saver, manufacturers typically recommend 20 to 40 air changes each hour, depending on the conditions.
These two rules help you determine the size of an evaporative cooling unit.
- The cfm rating required for 30 air changes per hour is calculated by multiplying the square footage in an area by the ceiling height.
- It will provide 30 air changes per hour if you have a 10-foot ceiling and 500 cfm per square foot of cooling capability.
Many manufacturers also provide model-specific recommendations to assist you in deciding how much room your units can cool.
Types Of Evaporative Coolers. Portable Coolers. Window Air Conditioners. Building-Wide Systems
You may utilize a few different basic designs for your evaporative cooler.
These portable evaporative and portable coolers can be utilized in manufacturing facilities, warehouses, and other locations where spot cooling is required.
Window cooling coolers, which may be stored and utilized in homes or workshops during the winter, are quite handy.
Central evaporative chillers are permanently placed and linked to ducting to circulate air throughout a structure.
- Roofs are outfitted with down-discharge central evaporative coolers.
- Central side-discharge Evaporative Coolers can be put on the building’s sidewalls to make maintenance easier. They can also be installed on building rooftops.
The following are the two most basic designs for central evaporative coolers:
- Evaporative coolers have multiple-inlet, louvered inlets on three or four sides. These inlets allow air to pass through and provide cooling through thin, fibrous plates.
- Evaporative cooling with a single intake Coolers suck air in through a single outlet. After that, the air is pulled via a water cooler pads. For single-inlet devices, a bigger blower motor is employed. This allows for increased ventilation and, when combined with bigger pads to keep the device cool, gives more power.
