Wet curtain provide efficient and economical cooling for greenhouses, while also helping to improve humidity control and plant growth conditions.Wet curtain and cooling fan is the most commonly used cooling method in greenhouse.
Product Description
Wet curtain cooling is a method that uses the principle of water evaporation to reduce the indoor temperature. The cooling system usually include one or morecooling pads and a negative pressure fan. The cooling pad cools by absorbing water and evaporating it, thereby absorbing the surrounding heat. At the same time, the negative pressure fan helps to expel the hot air in the room by generating negative pressure, thus further reducing the indoor temperature.
Characteristics of Wet Curtain
Operating principle: The wet curtain absorbs heat in the air through the evaporation of water, thereby reducing the air temperature. Specifically, water flows down from the top under the action of gravity, forming a water film on the surface of the corrugated fibers of the wet curtain. When the air flows through the wet curtain, the water in the water film evaporates, taking away a lot of heat, and reducing the temperature of the air passing through the wet curtain.
Material and structure: Cooling pad is usually made of polymer material and spatial crosslinking technology, with high water absorption, high water resistance, anti-mildew and other characteristics. In addition, the structure of the wet curtain is usually honeycomb or porous to increase its surface area and thus improve evaporation efficiency.
Cooling efficiency: The evaporative cooling efficiency of the cooling pad can reach more than 80%, which means that most of the heat is effectively removed from the air per unit time.
Humidifying function: While cooling down, the cooling pad can also increase the humidity of the indoor air, which is very beneficial for maintaining comfortable environmental conditions.
Application effect: The wet curtain system can significantly reduce the indoor temperature, for example, in the solar greenhouse, the positive pressure wet curtain fan cooling system can reduce the maximum temperature by 10 ° C in the external cycle and 7 ° C in the internal cycle.
Economy and environmental protection: As a cost-effective cooling method, wet curtains not only provide a cool environment, but also reduce energy consumption because it does not require additional cooling equipment to directly reduce the temperature.
