An installation evaluation apparatus 10 for a greenhouse includes an input device 11, an insolation evaluation unit 12, and a presentation device 13. The input device 11 is configured to receive input of position information relating to a planned location for installing the greenhouse. The insolation evaluation unit 12 is configured to determine variation, according to the date and time, in an insolation amount in the planned location by performing a computer simulation using the position information input into the input device 11. The presentation device 13 is configured to visualize and present the variation in the insolation amount according to the date and time, determined by the insolation evaluation unit 12.

A light shielding net, which can improve productivity by facilitating a weaving process, can be wound by a winding device due to a high winding strength, and can express various colors, thereby adjusting a light shielding amount and improving a design aesthetic sense. To this end, a warp yarn is made of a PE monofilament, the weft yarn is made of a PE film, and the two warp yarns are repeatedly woven in a Leno weave form surrounding each weft yarn.

The invention concerns a foldable greenhouse screen (2) comprising strips (11) of film material that are interconnected by a yarn system of threads (12) by means of knitting, warp-knitting or weaving process to form a continuous product, at least some of said strips (11) comprising a substrate (061) covered with a stack of thin films (063) on a first side of the substrate, so that said greenhouse screen has: a transparency coefficient of at least 40% but no more than 80% in the range of solar radiations, and a reflection coefficient higher than 70% in the middle infrared.

The present disclosure relates to a greenhouse having an inflatable and thermal insulation system. The greenhouse includes a lateral frame, a vertical frame, a top cover, an inflatable and thermal insulation system and a plurality of rotary shafts. The vertical frame is arranged at left and right sides. The lateral frame is arranged above and supported by the vertical frame. The top cover is arranged above the lateral frame. The plurality of rotary shafts are provided at both ends of the lateral frame, and at a top end of the vertical frame. The inflatable and thermal insulation system includes an air compressor, a dust collector, a dehydrator, a dryer, a constant-pressure and air-releasing controller, and a thermal insulation quilt which are communicated with each other in this order through a pipeline. The thermal insulation quilt is provided in the lateral frame and the vertical frame. The greenhouse has a simple structure, reduces manufacture cost and maintenance cost. The greenhouse has an independent air chamber, which provides a stable air layer with less air convection and ensures thermal insulation property.

The present invention relates to the environment controlled multi span structured greenhouses equipped with the modules Z1 to Z7 and plurality of sensors. Z1 comprises a capture manifold, a compressor, tanks T1, T2, Ta, and a release manifold, Z2 comprises an earth tube heat exchanger for very low cost heating and cooling of greenhouses in respective cold and hot locations, substantially reducing fossil fuel use, Z3 maintains greenhouse air relative humidity at a defined set point, Z4 harnesses bio-thermal energy, Z5 reduces global warming by preventing greenhouse carbon dioxide from being released into atmospheres, Z6 uses activated nutrients solutions substantially reducing input cost in drip and foliar dozing, Z7 comprises a film fixed to the greenhouse roof and to the four external sides' and automated 0 to 100% roll on and roll off thermal shading curtains wherein the greenhouse does not comprise gutters.

The present disclosure provides using stratification of air to reduce the amount of air in a greenhouse to manage and a conditioning chamber to precondition air prior to the air having contact with plants. A light deprivation chamber is provided with a centerline vent and operable louvres to recycle warm air and to be able to reduce the area of the building to heat by closing the light deprivation cover to create a smaller chamber to heat and recycle to conserve heat and take advantage of the heat from grow lights. The present disclosure further provides being able to cycle warm air from an upper air sink chamber back into the an air intake/conditioning chamber to conserve energy and using air tube fans to deliver quality conditioned air from a conditioning chamber to all the plants.

A solar powered greenhouse is an apparatus that harnesses electricity from sunlight and manages sunlight exposure with plants housed within the apparatus. The apparatus includes a housing, at least one photovoltaic glass layer, at least one adjustable-opacity panel, a solar inverter, a solar batter, a microcontroller, and a control pad. The housing maintains a desired environment for plants. The at least one photovoltaic glass layer allows sunlight to enter the housing, collecting and converting the sunlight into direct current (DC) electricity. The at least one adjustable-opacity panel controls sunlight entering the housing. The solar inverter converts the DC electricity into alternating current (AC) electricity. The AC electricity is stored with the solar battery. The at least one photovoltaic glass layer, the at least one adjustable-opacity panel, the solar inverter, the solar battery, and the control pad are controlled by the microcontroller and managed by a user with the control pad.

Top furling automated retractable greenhouse cover is a retractable cover for a greenhouse that is mounted on top of the greenhouse. Top furling automated retractable greenhouse cover comprises: a spine clamp, a left furling cover assembly, a right furling cover assembly, a hinge pin assembly, and an electrical control box. Left and right furling assemblies each comprise a curtain or cover, a furling rod, a furling motor, and a support arm. Electrical control box sends electronic signals to cause left and right covers or curtains to furl above the greenhouse when retracted and to unfurl down to the ground when extended to cover the greenhouse. The top-mounted design allows efficient use of gravity to apply tension to the furled rolls.
