Charles. So far in my attempts I have set up a loop to loop heat pump in
the detailed interface which will pull heat from the chill water return and put
it into the hot water return. However, I am using ground source cooling
and do not want the heat pumps to provide just cooling. Is there a way
for the heat pumps to just provide heating and not cooling?<o:p></o:p></span></font></p>

am currently trying to model a system which uses a water source heat pump. I
have never modeled this system before, and was wondering if any one had any

Any help would be much appreciated.<o:p></o:p></span></font></p>
