[Equest-users] eQuest Hot water Loop and WLHP

[Krystyniak, Patrick via Equest-users]

Hello All,

I have a question regarding loops in eQuest.  The building I am modeling has water source heat pumps and other water cooled air conditioning units.  Per the building design all of these are on  the same hot water loop (boilers) and condenser water loop (cooling towers).  However, in eQuest when I specify the heating source for the heat pumps as "DX Coils (Heat Pump)" a WLHP loop is created.  This then requires its own boiler and cooling tower.  What would be the best practice to model this correctly?  Two options I have considered would be to change all the heating sources of the heat pumps to "hot water loop", but do not think it will provide the same outputs.  The other option was to keep the two loops and size each boiler as a fraction with respect to the capacity of the units.  Are either of these correct or is there a better method to properly model Water source heatpump and water cooled AC units?

Thank you,
