- Apr 18, 2020-

film greenhouse

Natural ventilation is relying on internal & external air thermal pressure and external wind pressure to achieve the purpose of exchanging indoor and outdoor air. With a reasonable natural ventilation design, can help with reduce thermal and humidity, as well as CO2 increasing inside greenhouse.

With the study of Beijing Agriculture Machinery institute and Beijing Kingpeng Corporation, a type of fully opened roof vent film greenhouse set up in Hainan province, in China. After several years study, this type of greenhouse shows a great ability on greenhouse ventilation. A whole system is using gear-rack drive system, which including reduce motor, gear & rack, insect proof net and drive shaft. Greenhouse gutter as the fixed axis to open & close roof window. It provides adequate ventilation with a ventilation ratio close to 100%.
