Open roof greenhouses provide a Gear Motor For Greenhouse natural environment for plant growth when the outdoor climate would work and an artificial environment when it’s too hot or cold. Opening the roof over the vegetation increases light intensity that may help to control the growth habit, flowering and crop timing. It also reduces electrical power costs as expensive fan cooling is not needed.
Several methods are accustomed to open the roof. Some manufacturers make a roof that opens by rolling up the one or double level of flexible plastic-type material glazing that operates the distance of the greenhouse bay. A little gear electric motor rotates a shaft that winds the plastic material on to it such as a window color. A light, second framework over the framework secures the plastic-type material from bellowing out during windy weather conditions. Starting and closing the roof can be either manual or automatic. Each aspect of the roof can be controlled independently for flexibility in cooling.
Folding roof greenhouses work very well in snowy climates as they can be tightly closed during winter. Most designs use standard vent hardware. Some have panels that hinge at the gutter and open up upward. Opening is nearly 100%. Others possess panels that are hinged at the ridge and one gutter and slide sideways on teflon bearings. Opening is about 85%. Most designs use rubber gasketing to seal the joints. Glazing can be cup, polycarbonate or film plastic-type material. Some manufacturers give a movable gutter to gather rainwater when the roof can be partially open up. Wind sensors should be installed to close the roof in stormy climate. Movable shade is generally installed with the open roof design. It reduces heat load by reflecting the suns rays back again out. The shade curtain ought to be of a porous style to allow heat to flee. In northern climates a power blanket may also be installed to reduce heat loss through the winter.
These structures contain a steel frame, versatile glazing and cable support. Woven UV stabilized polyethylene film produces a watertight glazing. Based on the cropping program, bracing of the structure can be external cables mounted on deadmen, inner compression braces or trusses with cable X bracing. Flat roof designs are used where there is little rain or snow. A-roof designs shed the rain and snow to an internal gutter system. Styles that will carry up to 35 lb/sq ft snow load and 100 mph wind loads can be found. The roof opens in sections by shifting the industry leading of the curtain. One gear motor will handle up to 50,000 sq ft of roof Heating is more difficult than in a typical greenhouse because of the single layer plastic-type material and higher infiltration through gaps and cracks in the seals.
