People standing on the beach feel particularly cool, because the seawater absorbs the heat in the air and evaporates, causing the air temperature to drop, which gives us cool cold air. Evaporative air-conditioner is a new generation of environmentally-friendly and energy-saving air conditioner developed based on this natural phenomenon by combining high-tech and artificial evaporative refrigeration technology. Evaporative air-conditioner uses the principle of water evaporation effect to achieve temperature reduction by physical means, and solves the problem of excessive emission of "Freon" in ordinary air conditioners. The utility model utilizes the wet curtain as a cooling medium, and the water flows uniformly from the top of the wet curtain along the corrugated surface of the wet curtain, so that the wet curtain is uniformly wetted from top to bottom, and when the wind blows the wind, pressure is generated to force the unsaturated air to flow through the porous. When wet drying the surface of the curtain, a large amount of moist heat in the air is converted into latent heat, forcing the air entering the room to decrease from the temperature of the dry bulb to the temperature of the wet bulb, increasing the humidity of the air, so that the dry hot air becomes clean and cool air, thereby The role of cooling and humidification.
