V. Wet curtain / fan cooling system
1. Working principle:
Wet curtain / fan cooling system utilizes the principle of water evaporation to achieve the purpose of cooling. The system uses domestic high-quality wet curtain, water pump system and domestic high-quality large air volume fan.
The core of the cooling system is to allow water evaporation of the wet curtain, made of corrugated fiber paper bonded together, due to the addition of special chemical composition in the raw material, corrosion resistance, long service life. A special water-conveying wet curtain ensures that the water is evenly wetted throughout the cooling wet curtain wall. When the air penetrates the wet curtain medium, the water-air exchange with the surface of the wetted medium converts the moist heat of the air into latent heat of vaporization, realizing the humidification and cooling of the air.
The wet curtain is usually installed in the greenhouse corridor, the fan is installed in the greenhouse at both ends. When the need for cooling, start the fan, the temperature inside the air forced out, resulting in negative pressure; at the same time, the pump will hit the water on the opposite side of the wet curtain wall. When the outdoor air is sucked into the room by the negative pressure, it passes through the gap of the wet curtain at a certain speed, resulting in the evaporation of water and cooling, and the cold air flows through the greenhouse, absorbing the indoor heat, and then discharged by the fan, so as to achieve the purpose of cooling.
The system adopts aluminum alloy frame, which is characterized by beautiful appearance and small thermal deformation.
