The invention discloses a regulating system and method for multilayer shading film of plastic greenhouse with adjustable shading rate. The upper film of the sunshade is a fully transparent film, while the middle film and the lower film are printed with dots, which are interlaced. Through the measurement and comparison of the warm light in the greenhouse, the combined control of the sunshade film is realized. Not only can it adjust its light blocking rate, but it also has a heat insulating effect when there is a certain amount of air in the film.

An atmospheric water generation system comprises water vapor consolidation systems configured to increase the relative humidity of a controlled air stream prior to condensing water from the controlled air stream. The water vapor consolidation system comprises a fluid-desiccant flow system configured to decrease the temperature of the desiccant to encourage water vapor to be absorbed by the desiccant from an atmospheric air flow. The desiccant flow is then heated to encourage water vapor evaporation from the desiccant flow into a controlled air stream that circulates within the system. The humidity of the controlled air stream is thereby increased above the relative humidity of the atmospheric air to facilitate condensation of the water vapor into usable liquid water.

A daylight redirecting window film formed by a flexible multi-layer film laminate with a total thickness of less than one millimeter and configured to be applied to an indoor-facing window surface of a building facade. The window film includes a pair of outer film substrates flanking a light redirecting core layer. The core layer includes a parallel array of channels defining total internal reflection (TIR) surfaces and linear optically transmissive structures protruding transversely thought the core layer and bonded to the outer film substrates. A light output surface of the outer film substrate which is disposed on an indoor-facing side of the laminate includes a two-dimensional pattern of light scattering microstructures which are configured to spread light at least in a plane that is perpendicular to the channels. The TIR surfaces intercept and reflect a portion of sunlight propagating through the core layer such that the window film redirects that portion of incident sunlight towards a plurality of divergent directions, forming relatively high bend angles.

The present invention concerns an elongated sheet (1) for covering agricultural cultivated plants (2), with a basic film (3) of plastic, wherein a ventilation area (5) extending in the longitudinal sheet direction (L) and having a plurality of ventilation openings (6) is provided in the central area (4) of the basic film (3), wherein a cover film (9) of plastic extending in the longitudinal sheet direction (L) of the basic film (3) is applied to the ventilation area (5), forming free spaces (11) for air exchange, and is firmly welded to the basic film (3) over a plurality of connection areas (10) following one another in the longitudinal sheet direction (L), and wherein the connection area (10) is designed to be inclined, at least in some areas, with respect to a weld start point (12) and a weld end point (13) with respect to the cross direction (Q) extending orthogonally to the longitudinal sheet direction (L).

Illustrative configurations of greenhouse shading systems are disclosed. One illustrative system includes a plurality of main trusses supporting a translucent material defining an interior space, a plurality of gantries; and a plurality of shades attached to the gantries and the main trusses. The main trusses, gantries, and shades cooperate to move the shades between a closed position and an open position thereby regulating the amount of light the entering interior space of the greenhouse.

The present invention discloses a glazing characterized through a high hemispherical light transmission together with an enhanced tuneable light diffusion, what we hereby call a highly transmitting glazing with optimized Hortiscatter. The glazing of the invention is particularly well suitable for a greenhouse. The invention is a global approach which allows to propose different glazing which can be utilized depending on the type of crop and the geographical zone, providing optimized Hortiscatter on demand

A greenhouse screen strips of film material that are interconnected by a yarn system of transverse threads and longitudinal threads by means of knitting, warp-knitting or weaving process to form a continuous product, wherein at least some of the strips comprise a film material in the form of a single- or multilayer polyester film is disclosed. The film material has a transparency of at least 93.5% and is provided with at least a first anti-reflective coating or layer on a first side of the film material.

An indoor plant-growing system is an apparatus that includes a housing, at least one trellis, a reflective foil, at least one panel light, and a plurality of strip lights. The housing contains the at least one trellis, the at least one panel light, and the plurality of strip lights. The housing maintains an environment to grow a variety of plants, preferably, vine-type plants. The housing includes a growing chamber and a nutrient reservoir. The growing chamber houses variety of plants, and the nutrient reservoir supplies the growing chamber with a water supply and nutrients. The nutrient reservoir maintained preferably with fish in addition to at least one environmental sensor and at lease one aerator. The at least one panel light and the plurality of strip lights provide thorough lighting needed by the variety of plants. The reflective foil reflects the light to ensure lighting within a fully grown vine plant.

The disclosure relates to a multilayer film having an ethylene-vinyl alcohol copolymer (EVOH) layer, and a container type house system having the same.

A controlled environment agriculture system is disclosed, in which the system includes a reflective curtain (100, 600) having a porous membrane with a reflectance value of at least 90%.
