Hi Mr. James

Saw your respond for Ashok, also I'm trying to do one simulation with water-to-water heat pump systems, without combination of Purchased system.

I'm having two troubles about this simulation:

1) The firs one is about Heat Pump Water to Water:EquationFit for Heatin&Cooling input data,
in my case rated heating capacity is nearly 25000 W while in example file is 34040,92 W.
My trouble is, can I use the same coefficients of GshpHeating and GshpCooling used in example file
respectively for heating and coolin as in my example ? and how is defined Rated Heating Power Consumption valuei example.

2) the second is about Grount Heat Exchanger Vertical similar trouble like first. I dont know how have to determine the values of this object
for example: number ohf boreholes, bore hole length and radius, ground, pipe, and fluid parameter parameters also G and LN/LTs values.

In few word don't know how have to fill these object in my case which have different heating/cooling capacity
and different site location so different ground parameters.

thanks in advance

waiting for your answer

all the best
Dashamir

Dear All

Is it possible to simulate with Water to water ground source heat pump with
vertical borehole ground loop heat exchanger without combination of
Purchased system.

Thanks in advance
Ashok
