Imagine you are sweating after finishing a good run outside and you feel a cool gush as you enter home. You might be thinking that the air condition machine is on. However, that may not be the case. There is a peculiar thing called evaporative cooling that keeps you warm during summers. This is a process in which the liquid water gets evaporated from the surface and henceforth the temperature of the surface is decreased. This means when sweat evaporates from the skin, it makes us feel cool. When you feel cool through evaporation, it is a natural occurrence. When perspiration evaporates, it absorbs heat and cools the body.
Principle behind Evaporative Cooling
The major principle behind evaporative cooling is that when heat is applied to water, it will change from liquid to vapor. As soon as evaporation happens, this heat is taken from the water that is retained in the liquid state and this will result in cooling a liquid.
When water is evaporated, the energy is lost and the temperature is reduced due to air resistance. There are two temperatures that are important to set while dealing with evaporative cooling systems and evaporative cooling cleaning services.
- Dry bulb temperature
This is the air temperature which is measured by a regular thermometer exposed to the air stream.
- Wet bulb temperature
This temperature is the lowest and can be reached only by water evaporation.
What Is An Evaporative Cooler?
A device that cools air through the evaporation of water is called an evaporative cooler. It is different from air conditioning systems. The regular AC systems use vapor compression while evaporative cooling operates by exploiting the enthalpy of vaporization.
How To Clean Evaporative Cooler?
An evaporative cooler is very important during summers. Also, it is important to regualarly clean these coolers to get rid of several types of dirt, slime, algae, and dust. The evaporative cooler cleaning services entails through cleaning of the motor, fan blades, interior reservoir, surfaces, exterior unit etc.
Tips For Cleaning
- Increase the efficiency
Before cleaning you should check all the parts thoroughly. It will not only increase the efficiency but also will prolong the life of the unit. The evaporative cooling cleaning service should be done on a regular basis. First, you should remove the unit from storage and should wipe down the evaporative cooling machine’s surface with a soft cloth. Though there are several evaporative cooling cleaning services, you can always do it yourself. During that, you should not use any detergents or chemical. This may damage the whole unit. Also, keep the cooling machine from direct sunlight. This is to prevent the color changes on the unit’s surface.
- Water tank cleaning
Before checking all the aspects of evaporative cooling cleaning services, you should make sure that the water tank is clean. If the water supply is hard water, this cleaning becomes even more important. You should start by rinsing the water tank. It can be done with mild and soapy water. Then it should be flushed out with clean water and then drain the water through a plug. The evaporative cooler also has a rear panel, and this should be fitted correctly before replacing the screws in it.
- Shut down when not in use
The important aspect to consider to keep the machine in good condtion for a long time is to regualry maintain it. For that, you should shut the system down when not in use so that dust and dirt can not accumulate on the vents. You should unplug the unit; and also the water supply should be turned off and drain the water.
