In today’s energy-aware society, many people want to find cooling systems that work efficiently to create a cool and comfortable atmosphere. In Utah and others with low-humidity, one of the most common choices is an evaporative cooling system.
An evaporative cooling system uses the process of evaporating water in order to cool down the temperature of the air. The evaporative cooler (sometimes called a swamp cooler) takes the outdoor air and passes it over several water-saturated pads. The combination of the hot air over the wet pads causes the water to evaporate into the air. This water causes the temperature of the air to drop anywhere from 15° to 40°F. The cooler air is then released into the room, pushing the warmer air out of the house. The air is pushed out through the windows, which are kept slightly open in order to allow the warm air to escape.
Evaporative coolers often have two speeds and a vent only option. The vent only option does not push the air over the wet pads; instead the fan in the cooler runs to keep the air moving during times of mild weather. Filters can also be added to prevent the dust from the outside air from coming into the house.
One of the big perks to evaporative cooling systems compared to air conditioners is that the cooler provides a steady stream of fresh air into the house. They also cost less than air conditioning, with about ½ of the installation fee and about ¼ of the energy bill.
Some of the drawbacks to evaporative cooling systems are that they require a higher level of maintenance than other cooling systems. They also only work effectively in areas with low humidity.
If you live in a dry climate and are concerned about the cost of your energy bill, consider choosing an evaporative cooling system for your home.
