Problem Description Enthalpy wheel not always needed: Most effective for large temperature differences Wheel causes pressure drop and consumes energy Accurate flow rates measurement needed: Cost effective means of measuring airstreams is needed Integrated into control system to control air flow
Objectives Bypass the enthalpy wheel: Flow measuring device: Determine increased flow rate due to decrease in pressure drop Determine annual energy savings due to reduced fan speed Flow measuring device: Develop cost effective means of measuring airstreams Requires an accuracy of 8% Ensure compliance with existing control system
