Evaporative air coolers are preferred over air conditioners because they consume less energy. When you use evaporative coolers you can reduce your energy consumption by more than 33 percent. However, you to run these coolers you require a lot of water. In places where the mineral content is water is high, you may require more water to flush the minerals through the unit.
The working of these coolers is simple and is based on the principles of evaporation. There is a small motor in the cooler that pumps water from the floor to the top, where it falls on the pads that are fixed on the sides. The second motor is used to drive the fan that pulls hot air from outside through the wet pads and pushed the cool air into your home. The water in the pads evaporates when hot air is pulled by the cooler. The water level in the machine in maintained with the help of a floating sphere which is similar to the one that is found in your water tank of your toilet.
Since evaporative air coolers can be used only in areas that are hot and dry, they are less efficient in places that have a humid climate. Humid climate has a negative influence on the working of these coolers as water does not evaporate fast and enough cool air is not generated. Also, these machines require constant supply of fresh water which may be a problem in dry area.
Unlike air conditioners, evaporative air coolers require constant care and attention of home owners. Since they work on the principle of evaporation, when water evaporates salts and minerals present in the water is left behind on the pads. If you don’t clean the pads, they will hard and will absorb less moisture. Some newer models come with timer that removes the salt water after certain number of specified hours. Since salt water is removed from the machine, you don’t have to go through the trouble of cleaning the pads.
