The bigger the mercury rises, the lower the thermostat goes. Yet an air conditioner isn't the only machine that can save your from the heat. While air conditioners are more expensive to buy and use, there is a gadget that promises cooling at a more reasonable price. Air coolers give you just the right amount of cooling to survive a hot day. They are cheaper to buy and can keep your electricity bills low. Keeping your indoor environment cool and comfortable during warm summer months can be a frustrating and often expensive task, to say the least. Evaporative coolers - also known as swamp coolers - offer an eco-friendly, healthy, and cost-effective alternative to traditional air conditioning systems.
Best evaporative cooler - Evaporative cooling is a simple, cost-effective method for cooling indoor spaces. However, depending on the climate where you live, evaporative cooling might not be the most effective option for you. Thus, understanding how evaporative air coolers work will help you decide if this is the right cooling solution for you.
Evaporative cooling occurs naturally all around us. For example, you feel it when you step out of a pool on a hot day and immediately feel a chill. These air conditioning effects take place because as dried out air goes by over drinking water, the dried out air will absorb a few of water. This absorption occurs when the temperatures and vapor pressure of water attempt to equalize with the air. As a result, water molecules turn into gas molecules and heat switches from the higher air heat to the lower water heat. Since the air circulates naturally, the area around it is cooled.
To consistently cool your home, residential evaporative air coolers build on this natural phenomenon, using a buff to draw warm, stale air inside the unit, where it passes over water-moistened pads to be cooled. During this process, the air is cooled up to 20 degrees. Then, the cool, rejuvenated air is circulated throughout your environment. Since the cool air is continually circulating and creating an air flow, your ambient heat can feel four to six degrees lower than the actual heat.
The key to effectively cooling your home with an evaporative cooler is hot, dry air such as what is found in desert areas like the southwestern United States. In fact, evaporative coolers are most effective during the hottest times of the day and when humidity levels are below 60 percent.
