Evaporative cooling is the most commonly used cooling system to combat heat. The functioning of this cooling system is very simple, and it changes overheat energy into cooling power. Evaporative cooling is a cost-effective and environment-friendly method of cooling up the space. Evaporative coolers are otherwise called swamp coolers.
Basic working principle of Evaporative Cooling.
Well, the working of evaporative coolers is fairly simple. Let’s explain this with an example; you would have probably noticed that the fluid sweat dissipates from the perspiring skin when you were perspiring, which causes a cooling sensation in your skin. Or you have likewise felt a similar sense by remaining before a fan after your shower, or you have additionally felt a fantastic and new sensation in the wake of splashing water on a specific space. These are the everyday instances of evaporative cooling. Evaporative coolers have emerged as a boon for working-class families who couldn’t bear the cost of cooling or heating system.
There is a science behind the working of this cooling system. It works on the fundamental of water evaporation. The water retains some measure of hotness energy in itself. That heat energy leaves the surface and the fluid because the hot particles convert the fluid into gas. This way, the gas takes heat alongside itself and leaves the spot, which further declines the temperature of the environmental factors. This evaporative cooling measure gives us a cooling impact. It helps in summer by decreasing the temperature by 15 to 40 degrees.
Key qualities of Evaporative Cooling & evaporative coolers
- Evaporative cooling is a cost effective option as compared to other cooling system.
- You can feel the cooling sensation in low mugginess.
- It assists with keeping up with the temperature of your encompassing through dissipation.
- It additionally helps in home improvement by extricating the hotness energy and giving us incredible outside air to broadness in sweltering summer.
- It comes in all sizes where you are allowed to pick as indicated by your inclinations.
- We can introduce evaporative cooling in two unique sorts, for example,
- Central establishment: To blow air just a single way or at a point of convergence.
- Duct framework: it is utilized by larges houses to appropriate the air in various rooms just as in the corridor
Size of the cooler- The size of the cooler is eventually going to impact the cooling efficiency of the system. If you have purchased a small cooler for a large room, you will not get efficient cooling; hence calculating the right size is paramount. This is calculated as CFM or Cubic Feet per Minute. To calculate this, you have to do the following calculations:
Multiply the square feet with the ceiling height and divide it by 2
For example, you have a room of 450 square feet and a ceiling height of 8; then the calculation would be
The upkeep of evaporative cooling is simple, and you can do it without help from anyone else. Thus, if you want the evaporative cooler to work seamlessly, it is important to clean it regularly. It has a few sections like supplies, siphons, channels, and cushions to be cleaned regularly. It would be best to change the cushions at regular intervals to ensure efficient cooling.
It has been helping numerous families in their home administration. Its expense is half in comparison with the other cooling alternatives available in the market. Evaporative coolers cost by the CMF( cubic feet per meter the ) of air they blow. Evaporative coolers work the best in low humid regions. However, it has a reverse effect when the humidity is high. It is reasonable for the family who needs to keep their home cool in the blistering summer
