Evaporative coolers, also known as swamp coolers, are a type of air conditioning system that cools the air through the evaporation of water. They work by drawing warm air through a damp pad or filter, which causes the water to evaporate and lower the temperature of the air. This cooled air is then circulated back into the room. Evaporative coolers are an energy-efficient and eco-friendly alternative to traditional air conditioning units, as they use less electricity and do not rely on harmful refrigerants. They are particularly effective in dry climates, where humidity levels are low.

Frequently Asked Questions (FAQs)
1. How effective are evaporative coolers?
According to the US Department of Energy (DOE), an evaporative cooler can successfully reduce the ambient temperature by 5 to 15 degrees—but even the DOE is quick to clarify that this process works only in areas with low humidity.
2. Do evaporative coolers work as well as air conditioners?
High humidity makes it harder for evaporative cooling to work. Under dry, hot conditions, an evaporative cooler can work just as well as a refrigerant-based air conditioner.
3. Do evaporative coolers work in the UK?
Put simply the answer is, no, the UK doesn't have a climate that is too humid for evaporative cooling to work efficiently - and, actually, 99% of the year, Great Britain presents climate conditions that are perfect for evaporative cooling.
4. What are the drawbacks of evaporative cooling?
The Disadvantages of Evaporative Cooling Although an evaporative cooler requires minimal maintenance, there can be a buildup of salts and mineral deposits if your area has hard water. Moreover, maintenance can be a lot more inconvenient and possibly dangerous if the cooler is located on the roof.
