What Are Evaporative Coolers?
Evaporative air coolers are a type of air conditioner that works by harnessing the power of evaporation to cool air temperatures. When water evaporates, it turns from liquid to gas. As it does so, the highest-energy particles leave the water first, and this leads to a drop in temperature. This is why a moist cloth on your forehead feels good on a hot day. Actually, its helping to lower your head’s temperature as the water evaporates.
How do Evaporative Coolers Work?
An evaporative cooling system takes basic evaporation and automates it to efficiently lower the temperature of the air in your home. In general, the machine will consist of a fan, a thick pad. A water reservoir and some additional controls for fine-tuning the results. The fan draws dry, hot air into the machine and across the cooler pads. In fact, these thick pads absorb water from the reservoir and have many layers to increase the surface area. Then, as the hot air crosses the pad, the water molecules on the surface evaporates. So it causes the air temperature inside the cooler to drop — often by as much as 20 degrees. The fan then blows that cold air into your room, where you can enjoy the chill on a hot day.
Maintenance Tips for Evaporative Coolers
One thing you should always know before you make a substantial purchase is the amount of maintenance that is going to be required. In fact, no matter what kind of appliance you buy, whether it’s an air conditioner or evaporative cooler, there are still some maintenance requirements that must be met in order to ensure that your unit operates in an efficient manner.
First, each system comes with a venting kit that allows the hot air to leave the room through an exhaust hose. Simply, this is often done through a window, drop ceiling or wall. Or, making this is a big factor in which system to purchase.
In an evaporative cooler, the amount of maintenance depends on the type of system. A window-mounted unit requires simple measures in spring and fall to prepare for use and storage. In a portable unit, the filters and water curtains require cleaning every few weeks in addition to draining at the end of the season. Fro that, properly maintaining your unit will result in a longer-lasting machine and faster cooling during use
