Abstract
A method of verifying and analyzing energy efficiency ratio (EER) of an HVAC chiller unit in accordance with the present invention provides verification and analysis of HVAC chiller units to build daily steady-state data and non-steady state data out of field dynamic EER values and provides analysis of the steady-state data, based on selected integer temperatures and tenfold load factors in the annual scale that are subject to the dynamic changes in temperatures and load factors along with chiller seasonal operation to build monthly or seasonal running EER trend, and to determine-management index values for a period of time and to determine whether energy consumption meets specified criteria, as a basis of comparison of calculations, and resulting amplitude ratios between before and after the energy-saving improvement and of totally saved energy.
