Description: A short-term monitoring point test requiring
measurement of (i) RMS power input, (ii) evaporator flow
rate, (iii) entering and (iv) leaving chilled water temperatures,
and (v) return condenser water temperature while the chiller
system operates at a range of thermal load conditions. A time
period for the test is selected such that the load and water
temperature variations are representative of annual operation
for the system. The temperature-dependent thermodynamic
model is then used to determine the coefficients of the model
to calculate COP as a function of load, chilled water supply
temperature, and condenser water return temperature.
