Evaporative cooling is a technique that uses evaporation’s capacity as a natural heat sink. Evaporative cooling may be direct or indirect. During direct evaporative cooling, the air’s water content increases due to being close to the evaporated water. Indirect evaporative cooling involves evaporation inside a heat exchanger, leaving the air’s water content unaffected.
How Evaporative Cooling Systems Operate
The core of the evaporative cooling system is the cooling pad, where the water evaporates and the air travels through to be cooled. Fluted cellulose sheets are bonded together to create cooling pads. The material is treated with specific compounds to prevent rot, assure a long service life, and need little maintenance.
A specialized water distribution system evenly distributes water over the cooling pads, maintaining a consistent flow of water that keeps the entire surface moist to maximum cooling capacity. Air is drawn through the pads due to fans producing a negative pressure. Water and air coming into contact causes evaporation. A system controls the water pump, and the fan disperses the cool air throughout the space.
What Are the Advantages of Evaporative Coolers?
More Eco-Friendly
In addition to using chemicals that harm the environment, refrigerated cooling can dry the air inside a house. Compare that to evaporate cooling, which uses water to chill the air and no chemicals.
The air generated from evaporative coolers is never recirculated. It is constantly exchanged with fresh air, unlike the air released from refrigerated air conditioners, so your eyes and throat won’t grow irritated and people with respiratory and health conditions can enjoy their time indoors.
Healthier Residents
Evaporative cooling allows building occupants to breathe fresh, rejuvenated air with a balanced humidity level because fresh air is introduced into the structure. This is crucial since temperature variations and humidity can lead to dry environments and health issues. Regular air conditioning can harm mucous membranes in the nose and throat.
A Good Option for Dry Climates
For locations with dry climates, evaporative cooling is highly effective and recommended because of the air’s low humidity and greater capacity to absorb water vapor in a dry atmosphere. Keep in mind that evaporative coolers employ humidification to lower the air temperature.
Evaporative coolers make people feel more comfortable by raising the air’s moisture content, which helps with dry weather effects, including skin dehydration, altered respiratory mucous membranes, rhinitis, and respiratory distress caused by drying out the throat and nasal lining.
Optimal Indoor Air Quality
Air purification is one of the key benefits of using an evaporative cooler. Air from all over your house or place of work is continuously drawn in by the cooler. This air must pass through evaporative pads inside the cooler to clean the air.
Alternative pads with improved microfibers are available if you or your family have allergies. These pads can significantly reduce allergens in the air. These replacement pads work wonders at eliminating allergens that can also aggravate respiratory conditions.
Energy Efficiency
Evaporative coolers have several substantial benefits over conventional air conditioners, such as lower cost and less energy usage. Evaporative coolers have unit costs that are roughly 50% less than traditional window air conditioners and 70% to 90% less than inverter air conditioners. In addition, evaporative cooling uses 50% to 90% less electricity than air conditioning.
Open Windows and Doors
In contrast to how a conventional AC system would perform, evaporative cooling works just as well with open windows and doors. Once more, this offers a pathway for stale, potentially contaminated air to leave, improving the atmosphere for occupants.
Affordable and Cost-Effective Installation and Maintenance
An evaporative cooler is simpler than an air conditioner, lowering installation and maintenance expenses. It operates primarily using a fan and a water pump because it lacks a compressor. Also, there are no unique operating fluids, particularly refrigerants. Remember that installing an air conditioning system necessitates specialized knowledge from an HVAC contractor.
