Evaporative Coolers (also known as eco-air conditioners, evaporative water-cooled air conditioners, coolers, 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 places, the key feature of eco-air conditioners is their energy-saving and environmental-friendly nature! It is a completely new eco-friendly product with no compressors, refrigerants, or copper pipes. The evaporative cooler operates on the principle of water evaporation to achieve cooling through a physical method, addressing the issue of excessive "Freon" emissions in conventional air conditioners. It uses a wet curtain as the cooling medium, with water flowing evenly down the wavy surface of the wet curtain from top to bottom, uniformly moistening it from top to bottom. When the fan draws air, it creates pressure that forces the unsaturated air to pass through the porous and moist wet curtain surface. This converts a large amount of air moisture into latent heat, causing the air entering the room 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 effect of cooling and humidifying.
