Evaporative Cooling Fans (also known as eco-friendly air conditioners, evaporative water-cooled air conditioners, cooling fans, air coolers, and water-cooled air conditioners) are a comprehensive evaporative cooling and air exchange unit that combines cooling, air exchange, dust prevention, and odor removal. In addition to bringing fresh air and lowering temperatures to industrial workshops and public spaces, the key feature of eco-friendly air conditioners is their energy-saving and environmental protection properties! They are a completely new eco-friendly product without compressors, refrigerants, or copper pipes. The evaporative cooler operates on the principle of water evaporation, using a physical method to achieve cooling and solving the issue of excessive "Freon" emissions from conventional air conditioners. It utilizes a wet pad as the cooling medium, with water flowing evenly down the wavy surface of the wet pad from top to bottom, ensuring the pad is uniformly moistened. When the fan draws air, it creates pressure that forces unsaturated air to pass through the porous, moistened pad surface. This converts a large amount of air moisture into latent heat, causing the indoor air to drop from dry bulb temperature to close to wet bulb temperature, increasing the air humidity. This transforms dry, hot air into clean, cool air, thereby achieving the effects of cooling and humidifying.
