Patent ID: 7802734

Claim:
A fully integrated, packaged air handling system for air handling, control, and monitoring of constant and variable volume systems comprising a mixing box housing fitted effectively upstream of a primary or secondary mover with variable terminal device inlets for OA/RA (Outdoor Air/Return Air) mixed airflow; a means of determining OA/RA mixed air quantity and OA/RA mixed airflow enthalpy; a means of controlling OA/RA mixed air quantity and OA/RA mixed airflow enthalpy; a main damper housing fitted effectively downstream of a primary or secondary mover; a means of main damper control situated downstream of the mover(s); a primary and secondary mover of axial, radial, or centrifugal type arranged in-line or parallel; a plurality of terminal control dampers situated per zone of air distribution served by said air handling system; a means of terminal damper control per zone of air distribution served by said air handling system; a heat exchanger or energy recovery medium; a means of monitoring and controlling heat exchange and mass flow rate; a means of monitoring and controlling a point of system operation through interpolated or extrapolated data; a means of monitoring and controlling a point of sub-system operation through interpolated or extrapolated data; a means for determining air changes; a means for determining volume of a vessel; a means for leakage testing; and a housing frame enveloping all components.
