Air and soil treatment apparatus for a greenhouse |
摘要 |
An upright rectangular housing provided with air driving means for generating an airstream into which a number of ingredients, necessary to the life support of vegetation within a greenhouse, is injected for airborne distribution throughout the greenhouse, in addition to a ground level irrigation system fed by a reservoir in the housing containing the liquid components of the ingredients, while the temperature of the greenhouse is controlled by a pair of air intakes in the housing which selectively admit recycled air through a heater which raises the temperature when necessary or outside air if the temperature is to be lowered. Additional cooling is achieved by the adiabatic heat transfer of a water spray or the expansion of a gas within the housing of the apparatus.
