Evaporative Coolers (also known as Eco-Air Conditioners, Evaporative Water-Cooled Air Conditioners, Air Coolers, Cooling Machines, Water-Cooled Air Conditioners) are a comprehensive evaporative cooling and air exchange system that combines cooling, air exchange, dust prevention, and odor removal. In addition to bringing fresh air and reducing temperatures to industrial workshops and public spaces, the key feature of Eco-Air Conditioners is their energy-saving and environmental-friendly nature! They represent a new eco-friendly product that is free of compressors, refrigerants, and 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, where water flows evenly down the wavy surface of the pad from top to bottom, uniformly moistening it. When the fan draws air, it creates pressure that forces unsaturated air to pass through the porous and moistened pad surface. This converts a large amount of latent heat from the air, causing the indoor air to drop from dry bulb temperature to close to wet bulb temperature, increasing its humidity. This transforms dry, hot air into clean, cool air, thereby achieving the dual effect of cooling and humidifying.
