Reviews the standards and engineering literature for testing fans, pumps and chillers for HVAC applications. Notes that each investigation generally applies a unique set of measurement protocols for testing and evaluating energy performance and there have been few efforts to date to develop a common set of in-situ test methods for energy evaluation. As a result, ASHRAE recently completed Research Project 827 to develop such methods. Briefly presents an overview of the methods specifically as they relate to existing procedures.
