Getting to Know Your Evaporative Cooler: The Basics

Evaporative coolers are the more eco-friendly and cost-effective solution for cooling your home, but they are not new technology. Forms of evaporative coolers have been around since the time of the pharaohs. Egyptian pharaohs used to have slaves cool them by moving their fans over basins of cool water, or by soaking wool cloths in cool water and using them as fans. Although evaporative coolers may seem like innovative technology, they’re really only a modern way of making use of ancient practices.

If you’re thinking of installing an evaporative cooler for your home or business, or you require new or replacement evap cooler parts in Phoenix, AZ, here are a few basics you should know about these fascinating systems:

  • The evaporative cooling process: As the name suggests, evaporative coolers (also known as swamp coolers) use evaporation to cool the air. It was Benjamin Franklin who discovered that evaporation, such as sweat evaporating off of one’s body, is actually an excellent way to cool down. Today, we know that liquid evaporates by shedding molecules into the air, changing from a liquid to a gas. As the molecules become suspended in the air, they draw some of the heat from the hotter air, cooling it down as the water and air find equilibrium. The process also cools the remaining liquid, as hotter, faster-moving molecules are the most likely to escape into the air. Evaporative coolers work by harnessing this cooling reaction and circulating the cooler air through the house.
  • The parts of your system: Although the technology that goes into evaporative coolers may seem complicated, it’s actually quite simple. In fact, only a few evap cooler parts in Phoenix, AZ are needed to create an effective evaporative cooling system for your home. The four main parts of your system include evaporative pads, a water pump, water distribution lines, and a fan/blower. Although a few other evap cooler parts in Phoenix, AZ make up your evaporative cooler system, these four parts do the bulk of the work.
  • How your system works: Now that you understand the process and the parts that go into making an evaporative cooler, we can get into how your evaporative cooler system actually does its job. The water pump circulates water from a reservoir onto the evaporative pads. Then, the fan draws air from the outside into the unit and through the saturated pads. As the air passes through the saturated pads, the air is cooled through the process of evaporation that we discussed earlier. Once cooled, the air is circulated into your home.

There are many benefits to opting for an evaporative cooler vs. your more traditional HVAC system. Now that you understand a little more about the technology that goes into evaporative cooling systems and how they work, you can decide if an evaporative cooler is the right choice for your home or business.
