Project Description:
The purpose of this project is to research the feasibility of producing a prototype, air flow measurement device for ventilation systems that is energy efficient, accurate, cost effective and maintenance free. This technology will be used to measure and control outdoor intake airflow rates, exhaust airflow rates and the airflow rates supplied to occupied spaces in buildings.
Proposed Outcomes:
· Prototype air flow device capable of measuring actual air flow within +/- 10% over the full range of operating conditions.
· Control technology that will enable fan pressure resetting and demand-controlled ventilation.
Anticipated Benefits:
· Design that is less prone to fouling, is sensitive to variations in airflow velocity distribution within the duct and requires less maintenance.
· Reduce the cost of manufacture and installation using low cost components and elimination of the need for a separate duct section dedicated to airflow measurement.
· Potential to reduce energy consumption in California by .055 quads (1 quad = 2.93 X 1012 kWh) of which .035 quads is related to reduced electrical consumption which is equivalent to $326 million per year.
