Heating and cooling energy consumption measurements are critical for operations, controls, and fault detection and diagnosis (FDD) of heating, ventilation and air conditioning (HVAC) systems. Generally water flow has to be measured in order to determine energy consumption in either chilled water systems or hot water systems. Cost-effective and accurate water flow measurements are essential to develop energy meters. Since pump performance relates the actual pump water flow to pump head and power, theoretically the water flow through a pump can be determined by other pump performance characteristics, such as pump head and motor power. This paper presents the theoretical model of pump flow stations based on measured pump head and motor power, and the experiments and results of a cooling energy meter using a pump flow station developed on the chilled water system at a facility. 2010 ASHRAE.
