Evaporative air conditioning is a cooling method that uses the natural process of evaporation to lower air temperature. It works by drawing warm air through water-saturated pads, where the air cools as moisture evaporates. This system is energy-efficient and environmentally friendly, making it a popular choice in dry climates. Unlike traditional refrigeration air conditioning, which uses refrigerants and compressors, evaporative coolers require less energy and have lower operating costs. They are best suited for areas with low humidity, as high humidity can reduce their effectiveness. Overall, evaporative air conditioning offers a simple and sustainable way to cool indoor spaces.
