cooling system Negative Pressure Cooling
Realized by the principle of water evaporation and cooling. When the air penetrates the water curtain, it exchanges heat with the water vapor on the surface to realize the humidification and cooling of the air.
The combination of an exhaust fan and a wet curtain is often used in agricultural settings and greenhouses to achieve negative pressure cooling. This system works by pulling air through the wet curtain, which causes evaporation and lowers the temperature of the air. The exhaust fan then removes the cooled air from the greenhouse, creating a negative pressure environment.The wet curtain, also known as a cooling pad, is typically installed on one end or side of the greenhouse. It consists of a series of wetted pads through which air is pulled by the exhaust fan. As the air passes through the wet pads, the water evaporates, which cools the air. The exhaust fan then draws this cooled air out of the greenhouse, creating a negative pressure that facilitates continuous air circulation and cooling.By combining the evaporative cooling effect of the wet curtain with the air removal capability of the exhaust fan, the negative pressure cooling system helps maintain a comfortable and stable environment for plant growth within the greenhouse. This approach is often more energy efficient than traditional air conditioning systems and can be particularly effective in hot and dry climates.Overall, the exhaust fan and wet curtain combination is a popular method for achieving effective and efficient cooling in agricultural and greenhouse environments.
Keep in mind that cooling demands vary based on location and greenhouse model. It helps force warm air out and cool air in. It keeps air moving.
