Abstract: The present invention relates to an adaptable controller for controlling environmental systems, and more particularly to an improved computer-controlled irrigation and lighting system. Scheduling is selected using a unique graphical user interface and is transmitted to the controller remotely. Sensing devices for water flow to determine leaks and calculate usage using venturi are provided which communicate with the controller to adjust output in real time based on the measurements.

Abstract: An improved air-to-air, heat-and-moisture exchanger is described which facilitates the simultaneous transfer of both heat and water vapor between two streams of air while greatly inhibiting the transfer of pollutant gases. A rigid encasement supports a stack of flat, thin-film composite membranes that are held in parallel, spaced-apart relation, thereby forming a box-shaped exchanger. The membranes are synthesized by interfacial polymerization, a process whereby a thin, non-porous film may be uniformly deposited onto a porous substrate material. The thin film is hydrophilic so as to provide high water vapor flux together with excellent selectivity against the transfer of other gases and vapors. The substrate provides mechanical support.

Abstract: Heat exchanger which is a draw-through, self-contained, central ducted system. Heat exchanger can be used with a furnace or installed separately in any system. Supply and exhaust direct-drive blowers provide air flow against high resistance laminar, straight-thru/non-turbulent air flow of true cross-flow sized elements providing separation of air flow for side-by-side air flow with counter-flow heat transfer. The system is heavy duty, aluminum, cross flow, double-pass heat exchanger. The system includes drain pans and front and back access panels which provides easy access to the heat exchanger for cleaning as required. The electrical parts are on a slide out tray for easy servicing. The heat exchanger can be used in residential, commercial, or industrial environments.
