in the modeling of pump systems, according to 90.1, it should be primary/secondary systems with VSD on the secondary pumping loop.
I wonder how to model this in E+.
Besides, how to know the four coefficients of the variable speed pump? in E+, it is said that the variable speed pump model is described in the ASHRAE secondary HVAC toolkit, but I don't have it.
Can anybody give me a hint?
Thanks!
