Development and Validation of a Fan Performance Model for Typical Packaged HVAC Systems
Year: 2010
Abstract: INTRODUCTION
Fan performance characteristics, especially fan power consumption, is critical for the investigation of the HVAC system operations optimization and energy saving strategies. Simulation software, such as DOE-2, HAP, eQUEST, assume that: (1) each fan operates on a single system curve that uniquely maps airflow to static pressure; (2) fan system efficiency is a direct function of airflow; (3) and a second-order equation sufficiently models both of these effects. A blackbox regression model is used, producing the fan system power draw as a function of the percent design airflow using a second-order equation.
