[Equest-users] Modeling Complicated CHW Distribution

Dear All,

Is eQuest able to model the following?

3 rooftop air cooled chillers are running on glycol - water mixture and 
the mixture is brought to heat exchangers via a constant flow primary 
loop. A second loop, running on VSD pumps, takes the heat transferred 
water and feeds three other secondary loops serving different systems in 
the building.

I see that nesting of secondary loops is not possible in eQuest.

How to account for the extra pumping energy created by two loops on the 
heat exchangers?

How to account for transfer losses in the heat exchangers?

Thank you,

Omer Moltay
