Evaporative Coolers are also called swamp coolers and open space coolers. They were created to be an economical and efficient way of cooling the air. Evaporative Coolers are often considered a more cost-effective alternative to traditional Air-Conditioning, which can be costly in terms of installation and maintenance. Evaporative Coolers, unlike Air Conditioning, produce cool air through the evaporation of water. This is a natural process.
Simply put, water vapor is formed when liquid water absorbs a large amount of heat. This process is also known as Latent Heat Evaporation. This heat is carried along by the water vapor that has evaporated into the atmosphere. This heat is removed, resulting in cooler air. Evaporative Coolers use this cooling phenomenon to create cool air that can then be distributed throughout buildings and open spaces to those who require it.
Evaporative Coolers: How Can They Take Advantage Of Evaporative Cooling
Evaporative Coolers utilize a high-efficiency cooling medium called evaporative cool pads to aid in evaporation. The cooler unit circulates water around the cooling pads’ walls, which keeps the cooling media continuously wet. The cooling pads draw in air and evaporate the water. This cools the air.
1. A water pump circulates water from a water basin to the top cooling media, keeping it constantly wet.
2. Running fans cause the warm outside air to be drawn inside the cooler by passing through the cooling media.
3. Water evaporates as the air passes through the wet media. This is what causes the cooler’s intake air to cool down.
What Cooling Results Can Evaporative Coolers Get?
Evaporative cooling is a natural scientific phenomenon that depends on nature. The cooling effects of evaporative cool will depend on two factors: the outside relative humidity, and the outside air temperature.
Evaporative coolers provide better cooling performance when the relative humidity is low and the environment is dry. This is because the cooler the air outside, the more water can evaporate from the cooling media into the atmosphere. The cooler the air is left behind, the more water evaporates into the atmosphere. Evaporative Coolers are best suited for hotter and dryer conditions.
Evaporative Coolers can provide air as cold as 10 degrees Celsius cooler than the outside temperature in the best conditions. If the outside temperature is 38 degrees Celsius, the Evaporative cooler can cool that air to 28 degrees Celsius in ideal atmospheric conditions.
Where Are Evaporative Coolers Most Commonly Used?
Evaporative Coolers can cool semi-enclosed buildings and open areas. These coolers are often found in industrial settings such as factories, warehouses, workshops, and so on. They can also be found outdoors in commercial areas such as outdoor shopping areas, office complexes, and other open spaces. You may also find smaller Evaporative Coolers in residential areas.
Waterline Cooling Evaporative coolers are made to meet industrial-grade specifications and come in larger airflow capacities to suit the cooling requirements of large factories.
How Do Evaporative Coolers Compare To Air Conditioning Systems?
Evaporative coolers cannot be used to replace any HVAC or refrigeration system. Evaporative Coolers are not the same as Air conditioning. Air conditioning uses a mixture of coolants and refrigerants to produce chilled air at extremely low temperatures. It can produce extremely cool temperatures but it takes a lot of energy to do so. It is too expensive for industrial applications to chill entire factories or warehouses using Air conditioning.
For a cost comparison, an evaporative cooling unit costs 50% less to cool the same area than an HVAC system. Evaporative cooling systems are popular because of their cost-efficiency. They can provide a comfortable working environment at a fraction of the cost of air conditioning.
