Definitions

  • This invention relates to environmentally controlled greenhouses, and, in particular, to a greenhouse which extends the growing season of seasonal plants to last virtually throughout the calendar year.
  • Greenhouses generally provide an environment which assists in facilitating the growth of many types of vegetation.
  • the greenhouse's interior atmosphere may be controlled by other means,
  • a heating or cooling system may be installed to compensate for variations from the desired interior temperature created by too little or too much sunlight.
  • Reflective panels and insulating panels have also been pivotally attached to greenhouse walls and ceilings to assist in controlling the interior temperature.
  • the use of a greenhouse to extend the growing season of seasonal plants, such as strawberry plants, at an affordable cost has been illusive.
  • the requirement for a heating and cooling system sufficient to create a suitable environment for these environmentally sensitive plants has resulted in prohibitively expensive operating costs.
  • it is desirable to develop an environmentally controlled greenhouse which -may be utilized to extend the growing season of such plants and which is energy efficient and inexpensive to operate so that the farmer may profit from the sale of the plants or the fruit they bear.
  • One mechanism used to retain heat in the interior of the greenhouse during the nighttime hours or low sunlight conditions and to alleviate the problem of excess heating during warm weather comprises the placement of a translucent ceiling within the interior of the greenhouse.
  • a movable panel is placed on top of the translucent ceiling during conditions of nighttime or low sunlight conditions. The panel is then moved away from the ceiling to allow sunlight to infiltrate through the translucent ceiling when sunlight or warmth in the greenhouse is desired.
  • the translucent ceiling reduces the volume of space the greenhouse heating and cooling system must control, thereby reducing cost.
  • Examples of translucent ceilings with movable panels include the inventions disclosed in U.S. patent nos. 4,242,833 and 4,249,340.
  • 4,552,212 discloses a solar heating and cooling system for a building which includes adjustable ceiling doors or panels which may be placed over the building's translucent ceiling to retain heat therein.
  • U.S. patent no. 4,706,420 discloses pivotable insulative panels over the vertical exterior walls of the greenhouse and a retractable canopy which covers the roof of the greenhouse to thereby retain heat within the greenhouse.
  • the greenhouse disclosed in U.S. patent no. 4,414,784 may be attached to a balcony of an apartment. Since all balconies may not be oriented to properly take advantage of the optimum sunlight conditions for plant growth, a reflector panel is provided which aids in directing sunlight into the enclosure of the greenhouse.
  • the greenhouse disclosed in U.S. patent no. 5,056,259 includes a roof whose incline may be adjusted and a screen which may be used to control the amount of sunlight directed toward the interior of the greenhouse.
  • U.S. patent no. 4,929,444 discloses a solar building with a roof that may be adjusted to optimize the solar collection panel on the roof.
  • a greenhouse may require a supplemental heating and/or cooling system, depending on the climate and the weather at a particular installation.
  • auxiliary heating and/or cooling system which is a closed system. That is, under ideal circumstances, the heating and cooling system should be able to operate within the interior of the greenhouse and not require that significant amounts of external air be brought into the interior of the greenhouse.
  • external air is generally not optimum for the plant growth.
  • the external air may not be of the desired temperature, humidity or gas content as that of the interior of the greenhouse. Therefore, energy must be expended to "process" the external air to match that of the greenhouse's interior air.
  • a greenhouse Of importance in the use of a greenhouse is the actual floor plan of its interior space. Not only is it desirable to produce as much vegetation as possible, but it is also desirable to provide a greenhouse whose contents are arranged to permit easy access to the plants within the interior as well as to allow an individual to easily move about within the interior.
  • Hydroponics has gained popularity for use in growing plants within a greenhouse. In many instances, plant yields using hydroponics are equivalent to those for plants grown in fertile soil.
  • the placement of the large hydroponic tanks containing the solution for providing nutrients to the plants is a problem. To avoid detracting from the space available for hydroponic plant growth and to avoid inhibiting the movement of workers within the greenhouse, the tanks are often located outside the greenhouse. Thus, the solution in the tanks may need to be heated or cooled before feeding the plants. Such heating and cooling consumes energy which results in increased costs.
  • the hydroponic solution tanks are positioned within the interior of the greenhouse such that the solution does not need to be heated or cooled before feeding the plants and such that the tanks do not significantly reduce the number of plants that may be grown within the greenhouse's interior space.
  • One object of the invention is to provide a greenhouse which is able to optimize the amount of sunlight required for the growth of the plants therein as well to retain the heat within the greenhouse according to prescribed optimum conditions for the types of plants within the greenhouse.
  • Another object of the invention is to provide an auxiliary means for heating and cooling the interior of a greenhouse which is not prohibitively expensive to operate, is inexpensive to maintain, and which requires little maintenance or repair.
  • Another object of the invention is to provide an auxiliary heating and/or cooling system which is a closed system.
  • Still another object of the present invention is to provide a greenhouse whose contents are arranged to permit easy access to the plants within the interior as well as to allow an individual to easily move about within the interior.
  • Yet another object of the present invention is to provide a greenhouse in which the hydroponic solution tanks are positioned within the interior of the greenhouse such that the solution does not need to be heated or cooled before feeding the plants and such that the tanks do not significantly reduce the number of plants that may be grown within the greenhouse's interior space.
