Greenhouse ventilation system can be divided into two kinds of ventilation systems. One is continuous ventilation system. The

other is interlacing ventilation system. These two kinds of ventilation systems are now widely used in agricultural planting,

sightseeing and entertainment and other more fileds.

Continuous Ventilation System:

Greenhouse continuous ventilation system is mainly composed by gear motors, driving shaft, continuous ventilation rack and

pinion, and bearing plate. The gear motor in this system drives rack rotating through driving shaft. Continuous rack and pinion

work together to realize the openning and closing of the whole window.

Interlacing Ventilation System:

Interlacing ventilation system is made of gear motors, driving shaft, interlacing ventilation pinion and rack, bearing plate,

ventilation supporting wheel, push rod, push rod joint and other necessary parts. This kind of ventilation system is applied in top

window ventilation of Venlo type greenhouse. Because of the interlacing openning of top window, the outside air and the inside

air exchanges quickly, which assures the greenhouse always filled with fresh air.

Characteristics of Greenhouse Ventilation Systems:

· Improving the whole greenhouse efficiency.

· Assuring the abundant ventilation.

· Increasing the plants photosynthesis.

· Providing better environment for the growth of the crop.
