If you live in a dry region, try an evaporative cooling system for your home. Evaporative coolers bring in outside air and then lower its temperature through condensation. However, these units lose cooling power when relative humidity rises. For homes located in arid regions, evaporative coolers run on far less energy than air conditioners, reducing consumption and operating costs.
Our selection of residential evaporative coolers is affordable and efficient, a cooling system that won’t break your budget. View our affordable line of energy-efficient home cooling systems at RE Williams.
The process of evaporation happens all the time. Our bodies, for example, perspire in hot weather; through evaporation the sweat dries and drops our body temperature.
Whenever dry air passes over water, some of the
water will be absorbed by the air. That's why evaporative cooling naturally
occurs near waterfalls, at rivers, lakes and oceans. The hotter and drier the
air, the more water that can be absorbed. This happens because the temperature
and the vapor pressure of the water and the air attempt to equalize. Liquid
water molecules become gas in the dry air, a process that uses energy to change
the physical state. Heat moves from the higher temperature of the air to the
lower temperature of the water. As a result, the air is cooler. Eventually the
air becomes saturated, unable to hold more water, and evaporation ceases.
