VAV SYSTEM VOLUME CONTROL USING ELECTRONIC STRATEGIES.

Author(s) : ATKINSON G. V.

Summary

CONTROLLING THE ACTUAL OUTSIDE-AIR MINIMUM VOLUME INDEPENDENT OF THE VARIABLE SUPPLY FAN DELIVERY IS NECESSARY TO MEET MINIMUM VENTILATION AND POSITIVE BUILDING PRESSURIZATION REQUIREMENTS. SIMULATED EXHAUST-FAN FLOW SIGNALS CAN BE ADDED ELECTRONICALLY AND SUBTRACTED FROM RETURN-FAN AND OUTDOOR-AIR MAKE-UP VOLUMES TO BALANCE THE AIR FLOW REQUIREMENTS FOR BUILDINGS, MAINTAINING A DESIRED SPACE STATIC PRESSURE. ENERGY CAN BE SAVED BY ADMITTING ONLY THE REQUIRED OUTSIDE-AIR VOLUME AND BY CONTROLLING THE RETURN-AIR VOLUME FOR VARIABLE EXHAUST REQUIREMENTS, RESULTING IN LOWER RETURN-FAN BRAKE HORSEPOWER.
