An evaporative cooler is also known as a swamp cooler because it uses water to cool the air. Since evaporative coolers are an air conditioning alternative, it’s important to know the differences between the two devices.
Air conditioners rely on compressors and condensers to cool and recirculate the air inside a sealed room. Alternatively, a swamp cooler is better at cooling open spaces with good ventilation and easy access to fresh air. Swamp coolers utilize re-fillable water tanks to saturate internal pads. Once warm outdoor air passes through the water-soaked pads, the water evaporates and reduces nearby air temperature. This means that evaporative coolers can be a great option for people who want to stay cool with the windows open. But it’s important to note that swamp coolers are best suited for warm, dry climates. For people who live in hot and humid weather, an evaporative cooler will add even more moisture to the air and be less effective at cooling. This may make evaporative coolers sound kind of like a
humidifier — and they are, except humidifiers don’t use outside air and lack a cooling effect. Evaporative coolers are also different from your typical
fans, which can make your space breezy but not necessarily lower the temperature. So if you’re looking for a way to make your air cooler but still have access to the fresh outdoors, a swamp cooler may be the right product for you.
