IMPROVEMENTS IN AND RELATING TO ENVIRONMENT-CONTROLLED MULTI-SPAN
STRUCTURED GREENHOUSE
RELATED APPLICATION
The present application claims priority from Indian Patent Application No.
201811029265 filed on August 3, 2018, and Indian Patent Application No.
filed on November 15, 2018.
FIELD OF INVENTION
The present invention relates to environment-controlled multi-span structured greenhouses comprising low cost supplementary heating and cooling for low cost food production. The present invention also relates to low cost heating of premises such as residential and commercial premises including, for example, but not limited to, offices, malls, multiplexes, hotels, industrial units and the like, while reducing or eliminating the consumption and burning of fossil fuel. The present invention further relates to melting snow on surfaces, including for example, but not limited to, airport runways, railway tracks and roads, in relatively cold weather geographical locations. The present invention still further relates to clearing fog in the environment of a greenhouse in relatively cold weather geographical locations.
BACKGROUND OF THE INVENTION
In relatively cold weather geographical locations, there is the problem of very high capital and operating costs of supplementary heating greenhouses, which mostly comprises burning very substantial amounts of fossil fuels which co-produces carbon dioxide and other pollutants, most of which increase global warming and some of which are also harmful to plants in the greenhouse.
When a fossil fuel burns, it radiates heat and releases carbon dioxide. Once in the atmosphere, some of that carbon dioxide can linger for thousands of years and trap heat that would otherwise leak into space. As reported by researchers online in "Greenhouse gas-caused warming felt in just months.", ScienceDaily., 2 June 2015, Carnegie Institution, over the lifetime of released carbon dioxide, the trapped heat exceeds the heat released during combustion by a factor of more than 100,000.
Likewise, in relatively cold weather geographical locations, there is the problem of very high capital and operating costs of heating premises such as residential and commercial premises including, for example, but not limited to, offices, malls, multiplexes, hotels, industrial units and the like, which mostly comprises burning very substantial amounts of fossil fuels to heat, for example, water to 70-80 C for circulation into the heating radiators.
Similarly, in relatively hot weather geographical locations, there is the problem of very high capital and operating costs of supplementary cooling greenhouses, which comprises using substantial electric energy mostly produced by burning substantial amounts of fossil fuels.
There is also the problem of maintaining the crops in greenhouses free from diseases, pathogens and harmful organisms and pests such as bacteria, fungi, viruses, insects and the like etc.
The intensity or brightness of light is a function of the distance from the light source following an inverse square relationship. There is the problem in greenhouses of adjusting the height of an artificial light source to maintain the artificial light a predetermined distance from the top of the growing plants, which is very labour and operating cost intensive. As such, the greenhouse growers mostly install the artificial light source at a predetermined and fixed distance above the top level of a fully grown plant, the level at which a growing plant would achieve after a long duration such that the plants during their earlier growth stages derive minimal benefit from the artificial light source which leads to reduced productivity.
There is also the problem of melting snow on various surfaces such as, for example, but not limited to, roadways, railway tracks and airport runways. In many instances, snow on airport runways is melted by built-in heating modules in the concrete slabs of the runway mostly using fossil fuel or electric energy which is mostly a product of burning fossil fuels, whereas snow on roadways, railway tracks and the like is removed by earth moving machines which use diesel, a fossil fuel product.
Another problem is mist, a very fine continuous layer of moisture on the interior surfaces of the gutters of the greenhouse and of the film cover of the greenhouse, wherein during cold early morning hours, when temperature decreases and relative humidity saturates, a dense fog is formed in the greenhouse environment which also reduces light transmission into the greenhouse.
Indian Patent Application No. 201711025454, filed on July 18, 2017, and patent applications claiming priority therefrom, including U.S. Patent Application No. 15/844,354, all filed by the same present inventor, relate to an environment-controlled multi-span structured

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The intensity or brightness of light as a function of the distance from the light source follows an inverse square relationship. This relationship is illustrated by Figure 1, which shows the apparent brightness of a source with luminosity Lo at distances r, 2r, 3r, etc. As the distance increases, the light spreads out over a larger surface and the surface brightness decreases in accordance with a "one over r squared" relationship. The decrease goes as r squared because the area over which the light is spread is proportional to the distance squared.

Thus, in accordance with another aspect of the present invention, there is provided a storage facility comprising a first compartment for storing the captured relatively lower temperature hot carbon dioxide rich greenhouse air and a second compartment for storing the captured relatively lower temperature hot oxygen rich greenhouse air, wherein each of the first and second compartments are insulated from the exterior temperature of the facility such that the stored relatively lower temperature hot carbon dioxide rich air and the stored relatively lower temperature hot oxygen rich air remains substantially the same temperature as when it was captured without conditioning or cooling. Maintaining the relatively lower temperature hot carbon dioxide rich air and the relatively lower temperature hot oxygen rich air in the storage facility at substantially the same temperature as when it was captured without conditioning or cooling results in a minimal differential heating of the stored air before being released back in the greenhouse leading to considerable savings in heating cost and reducing the burning of fossil fuels.

As discussed above, there is the problem of fog developing in the greenhouse environment during cold early morning hours when temperature decreases and relative humidity saturates dense fog on the interior surfaces of the greenhouse which reduces light transmission into greenhouse. In an embodiment of the present invention, the release blower, together with the heating module, clears the fog from the interior surfaces of the greenhouse sides and roof by releasing hot air into the greenhouse which increases the relative temperature of the greenhouse air and reduces the relative humidity of the greenhouse air and, in turn, reduces the fog that has accumulated on the interior surfaces of the greenhouse sides and roof.
