Sawtooth Ventilation Multi-span Film Greenhouse

Editor：zenong　　Time：2021-10-28　　　Hot： ℃

The sawtooth type greenhouse has a modern appearance, novel structure, stable structure, smooth vision, strong light transmittance, up to 90%, and strong wind and snow resistance. Ventilation in the middle of each span of the greenhouse can be used for ventilation in a large area. At the same time, due to the principle of hot differential pressure, the gas with high temperature in the greenhouse is always at the highest point of the greenhouse, so the natural ventilation of the traditional greenhouse can be changed. Effectively reduce the temperature and humidity in the greenhouse, especially suitable for flowers and crops with low humidity requirements.

The Shading system can keep out redundant sunshine, preventing the plants from being burned in the greenhouse. And it can regulate the heat or reduce the cost for the operations.
Outside Shading System is fixed above the frame of greenhouse, supported by the uprights and beams. Outside shading net is made by black and round-wire materials and fastened by black polyester strings.

3)Cooling System
Our company is specialized at the products of cooling pads and fans, usually used cooperatively. The cooling pads are installed on one side of the greenhouse, the exhaust fans, the other. (The air-circulating fans are installed in the greenhouse.) The exhaust fans eject the air from the greenhouse (The air-circulating fans promote the circulation of the air in the greenhouse), negative pressure formed in the greenhouse. The air enters the greenhouse through the cooling pads, resulting in the effects of cooling, moistening and air-dedusting.
