Evaporative coolers have remained preferable options to control the climate since a long time now. Reason for this is that an evaporative cooling device gives tons of benefits as compared to any traditional air conditioner device. Especially, evaporative coolers make fewer pollutants in the atmosphere. However, before we should discuss the benefits offered by evaporative coolers to be a preferable option, we will talk about the device and its mechanism.
Overview of Evaporative Cooling Process and Evaporative Coolers
Evaporative cooling involves a cooling process, which takes benefit from the latent heat obtained from the water evaporation and absorbs the sensible amount of heat from the nearby air, which remains in its contact. Evaporative cooler type of air conditioning systems thus utilizes the cooling effect associated with liquid water evaporation for cooling a specific air stream indirectly or directly.
Components of an Evaporative Cooler
An evaporative cooler has the following components-
- Intake chamber
- Filter or filters
- Ukutshatyalaliswa kwamanzi
- Supply fan
- I fan fan
- Water sump
- Water sprays
- Re-circulating water pump
How Evaporative Coolers Work
Evaporative cooling units circulate water from various saturated cooling media and draw air across the wet media surface. Here, hot air thus absorbs the moisture content present in the saturated media to reduce the temperature of the air discharged from the respective cooling unit.
Why Evaporative Coolers are Better?
Evaporative cooling systems perform their functions in the best way whenever outside air in small amount circulates within the space where you employ the respective cooling device. This step also leads to the introduction of fresh air in the environment, while reduces the risk related to poor quality of indoor air.
Benefits to Use Evaporative Coolers
1. Supplies Fresh Air
The fresh air supply is a prime benefit associated with using evaporative coolers. With the amount of fresh air, you will have relatively fewer numbers of respiratory problems, while feeling yourself healthy. Fresh air is very much essential for any individual suffering from asthma or any other similar type of respiratory problems.
2. Adds Moisture Content to the Inhaled Air
Along with supplying fresh air, evaporative cooling devices add moisture contents to the inhaled air. Now, the question that comes to our mind is why moisture is essential. For this, we would consider the case of air conditioners, which remove moisture content from the air. Removal of moisture content from the atmosphere creates breathing-related difficulties and may even result in drying and cracking of the skin.
3. Causes Low Emission of Carbon Dioxide
Carbon dioxide releases a massive collection of gases, which may create a negative effect on both people and the environment. Positively, evaporate coolers release carbon dioxide hardly in the background. Thus, with less emission, you will help to you and the entire situation.
4. Drastic Reduction in the Operational Cost
A prime benefit associated with the installation of evaporative cooling devices is that they cause a severe reduction in the overall operational costs. The logic behind this is simple, i.e. evaporative coolers need only an electric supply to provide the necessary power to their fan units and pumps. Indeed, you will end up paying approximately 50percent less amount of operational costs per month.
Therefore, based on improved operations, low emissions and affordability, evaporative coolers are preferable among both homeowners and office owners today. The device may present in the form of a field-built system or a factory assembled type of packaged unit. It constitutes a prime component associated with a centralized hydronic system or a packaged type of unit system.
