Abstract:
1. A greenhouse environment control system comprising a greenhouse for growing plants, said greenhouse comprising a substantially enclosed structure comprised of a transmissive material that allows passage of sunlight, said substantially enclosed structure defining an interior in which plants may be grown; said environment control system comprising a plurality of subsystems, said plurality of subsystems including a generator subsystem, a gas cooling subsystem, a mixing subsystem, and an HVAC subsystem; said generator subsystem comprising a natural gas fueled engine producing a stream of exhaust gases and an exhaust gas treatment module converting the stream of exhaust gases to a gas stream comprised of nitrogen gas, water vapor and carbon dioxide; said gas cooling subsystem being in fluid communication with the generator subsystem and comprising a plurality of fluidly coupled heat transfer units, said plurality of fluidly coupled heat transfer units reducing the temperature of the gas stream to about 200° F. to 100° F.; said mixing subsystem comprising an inlet fluidly coupled to the gas cooling system, an outlet, a fresh air duct through which fresh air flows, a particle filter associated with the fresh air duct, the fresh air flowing through the fresh air duct being filtered by passing through the particle filter, a mixing chamber in which the gas stream is mixed with filtered fresh air to produce CO said HVAC subsystem comprising a plurality of fan coil units, each fan coil unit including a housing defining an interior compartment, a gas inlet being fluidly coupled to the outlet of the mixing subsystem and leading to the interior compartment, a gas outlet leading from the interior compartment, a coil contained in the interior compartment, said coil having an inlet and an outlet, and a fluid flowing through said coil, said fluid being at a temperature effective for cooling the CO
