What Are Evaporative Coolers? HereТs Everything You Need to Know
An evaporative cooler (also evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from other air conditioning systems, which use vapor-compression or absorption refrigeration cycles. Evaporative cooling uses the fact that water will absorb a relatively large amount of heat. Easy maintenance: These portable cooling units use removable, washable air filters. Our spot coolers are truly portable. They roll into place, and most of our units operate at standard electrical voltage. Warm air from the spot cooler is vented through an attached duct, allowing air to vent outside or into a drop ceiling.

Looking for a way to beat the heat? Understanding how evaporative coolers work is a crucial part of figuring out if one will work well in your home.
An evaporative air cooler is 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. In a dry environment, the simple process of evaporation can help lower the temperature of the air.
An evaporative air conditioner uses the same idea, but it adds technology to make the process more efficient Ч and less messy Ч than just spraying a room with water and hoping for the best. 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. These thick pads absorb water from the reservoir and have many layers to increase the surface area. As the hot air crosses the pad, the water molecules on the surface evaporate, which causes the air temperature inside the cooler to drop Ч 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. Evaporative coolers can have other useful parts built into them as well. Many utilize air filters and pads that are designed to improve air quality by reducing allergens and minimizing mildew growth Ч an important consideration for anyone with allergies or other respiratory concerns.
A water pump, while not strictly necessary, can streamline the absorption into the cooling pad. Some models offer the option of adding an ice pack to further cool the air the fan blows out into the room. Varying fan speeds, oscillating functions and a remote control are also useful features.
A swamp cooler is often a term reserved for a whole-house evaporative air conditioning unit, while evaporative coolers can be any size Ч including compact, portable evaporative coolers. Permanent swamp coolers are large units designed to cool a whole house. Cool air flows down from roof-mounted systems, or it can be piped through ductwork to be directed to any location you like. Evaporative coolers have two major advantages over traditional air conditioners : energy efficiency and sustainability.
Both are due to the fact that evaporative coolers use far less electricity to operate; in fact, a standard air conditioner can use up to seven times as many watts of electricity.
This is because, in general, evaporative coolers only need to run the fan that draws airflow over the cooling pad. Standard air conditioning systems , on the other hand, rely on a compressor to press liquid refrigerant into a smaller space and then move it across a heat exchanger to pull heat out of the air.
This process requires a great deal of electricity to accomplish, in addition to the fan that send cold air out into the room. Using less electricity with an evaporative cooler means lowering your carbon footprint as well as paying less on your utility bills. It should also be noted that evaporative coolers use only water and no chemical refrigerants, which are harmful to the ozone layer.
This makes sense, of course, when you pause to break down how they work. Because these coolers depend on water being able to evaporate into the atmosphere, having a house full of dry air makes this process much more efficient. The water molecules can separate and float off into dry air much more easily than they can into humid air, which is already pretty saturated with water. In these arid locations, water will evaporate quickly and cool your air well.
The other reason that evaporative coolers are better in the Southwest than in other regions is because using them actually boosts the humidity level in your home.
As the water evaporates , it leaves the cooler and stays in the air in your home. If you live in the desert, this can be a real bonus for helping you stay hydrated and to keep your skin in good shape. In humid climates , however, this could be a deal breaker. Know Your Humidity Levels. To understand why, consider how your body feels on a muggy day. When you are hot, your body sweats to cool you naturally through the process of evaporation your sweat evaporates into the air and cools you.
The same thing happens with an evaporative cooler in a humid region: It pumps more moisture into the air, making it even more humid Ч and less likely that water will evaporate and make you feel cool.
The bottom line? If you plan to use an evaporative cooler effectively, make sure you live in a reliably dry environment. Try these tips for the coolest, most comfortable air possible:. An open window near the intake fan allows dry, warm air to drawn into the cooler for quick evaporation. This will keep your evaporative cooler functioning well and your air quality clean. Before you buy, make sure to check the recommended square fee that the cooler covers and measure your room to size the cooler appropriately.
Unless your cooler is designed specifically with an ice pack for its reservoir, adding ice to the water can actually slow down the evaporation process and leave you feeling less cool.
A portable evaporative cooler is a great way to see if evaporative cooling will work in your home without making a big investment upfront. Portable coolers come with wheels to easily move them from room to room for a little extra chilling exactly where you need it.
You can also use these outside as long as you can reach an outlet to plug them in. This makes portable evaporative coolers welcome accessories to a picnic, pool party or any other outdoor gathering where people would appreciate a cool breeze.
