Evaporative coolers are also known as open spaces and swamp cooler. Evaporative coolers were created to provide cooling air that is efficient and cost-effective. Evaporative coolers are more affordable than traditional Air-Conditioning. They can also be more difficult to set up and require frequent maintenance. Evaporative coolers, unlike Air Conditioning, produce cool, dry air through the evaporation and condensation of water. This is a natural function.
Put water vapor results when liquid water absorbs a lot of heat. This process can also be called Latent Heating Evaporation. This heat is carried along with the water vapor, which has evaporated in the atmosphere. This heat is removed, which creates cooler air. Evaporative coolers create cool air. It can then be spread throughout buildings and open areas to those who request it.
Evaporative Coolers: How Can They Benefit From Evaporative Cooling?
Evaporative cooling devices use high-efficiency cooling materials called evaporative hot pads to assist in evaporation. The cooler unit circulates warm water around the cooling pads’ walls. This keeps the cooling media moist. The cooling pads draw water in and evaporate it. This cools the air.
- A water pump circulates the water from a water reservoir to the top cooling media, keeping it continually wet.
- Running fans pull the warm air outside through cooling media to cool the cooler.
- As the air passes the wet medium, water evaporates. This is what causes the cooler’s intake to cool down.
What Cooling Results Can Evaporative Coolers Get?
An evaporative cooler is a natural science phenomenon that depends on the environment. Two factors influence the cooling effects of evaporative cooling: the outside relative humidity and the temperature outside.
Evaporative cooling provides better cooling performance when relative humidity and the surrounding environment are dry. This is because cooler air can evaporate more water from the cooling media into the atmosphere. The greater the amount of water that evaporates into the atmosphere, if the air is kept cooler than the outside. Evaporative coolers work best under hotter, dryer conditions.
Evaporative coolers can make air 10 degrees Celsius cooler than outside temperature under the best conditions. If the temperature outside is 38 degrees Celsius, the Evaporative cooler can cool the air down to 28 degrees Celsius.
Where Are Evaporative Coolers Most Commonly Used?
Heater Coolers cool semi-enclosed structures and open areas. These coolers are common in industrial settings such as factories, warehouses, or workshops. These coolers are also common outdoors, such as in commercial areas, outdoor shopping areas, office buildings, and other open spaces. You might also find smaller Evaporative coolers in residential areas.
Waterline Cooling Electronic Coolers are manufactured to industrial-grade specifications. They come in larger airflow capacity to meet the cooling needs of large factories.
How Does Evaporative Cooling Compare To Air Conditioning Systems?
Evaporative coolers cannot be used in place of an HVAC or refrigeration system. Evaporative coolers are not equivalent to Air conditioning. To create chilled air at extremely low temperatures, air conditioning uses a mixture of coolants/refrigerants. However, it is capable of producing extremely cool temperatures. It does require a lot of energy. It is too costly for industrial use to chill whole factories or warehouses.
To give you an idea of the cost, a cool evaporative unit costs half as much to cool an area as an HVAC system. Evaporative cooling is popular for its efficiency and cost. Evaporative cooling systems are cost-effective and provide a pleasant working environment at a fraction of air conditioning.
