Iâ??m modeling a
chilled water loop whose water is chilled by a heat pump. Iâ??m modeling the heat
pump with the object HeatPump:WaterToWater:EquationFit:Cooling
The heat pump transfers the heat to a vertical ground
heat exchanger.
Consider the following schematic picture:

Among the
output variables Iâ??m not able to find the temperatures in the nodes A, B, C,
and D. Is obtaining their values in the output possible?
Getting the
design values is problematic. Of course, the temperature of the node E depends
on the heat gains (weather data and activities in the building). From your
experience, what are typical values for the nodes G and H?
I read at page 628
of the â??Input-Output Referenceâ?? that the model is relative to a â??reciprocating
compressorâ??. The compressor that Iâ??m modeling is scroll. What is the best way
to model it? Should I change the â??cooling capacity coefficientsâ?? and the â??cooling
compressor power coefficientsâ??? Unfortunately I know
only the rated (nominal) values of the characteristic parameters.
