Re: [EnergyPlus_Support] DHW system pipe network

[Edwin Lee <leeed2001@xxxxxxxxx>]

You can put the heat transfer pipe on the supply side of the loop.  You can still put the pipe:indoor objects in the zones of your choice, but in v5 they need to be placed on the supply side half-loop.  I can't remember for sure the status of this model, but in the next release, this constraint "may" be relaxed.  Putting it on the supply side should satisfy most models though.

Hello all,

I am trying to model heat loss through a domestic hot water pipe system. Essentially, I am trying to model different lengths of hot water piping going to different end uses.

The E+ I/O reference states that heat transfer cannot be modeled on the demand side due to simulation constraints (I also got an error when I tried to use the pipe:indoor object in the network which worked fine with the pipe:adiabatic object).

Is there a way to model this?

Thanks,
Vrushali
