[Equest-users] DWH Per Thermal Zone

Tue May 3 07:48:38 PDT 2016

Yes,
You could use SOURCE-TYPE = GAS. For example, if you have the peak hot water flow and a schedule that modifies that flow, you would have to convert that to the GAS peak taking into account the seasonal efficiency of the suite DHW systems.

You can then assign a fuel meter in each zone to capture the suite DHW energy use separate from the common house DHW system.

Thanks Christopher.  Do you mean I should add it in Internal Loads/Equipment/Internal Energy Sources?

You might model the house meter DHW as DHW but model the suite DHW as a source load in each suite space, then in the zone you can assign those source loads to a separate fuel meter. I think.

Thanks for the response guys.

I tired modeling one DWH per a zone using the zone location hoping that it would only serve that zone, but the usage is over 2,000 therms per year so that would be the whole building.

I might need to combine them.  The problem is that I have one floor that is on the house fuel meter and 20 apartments that are on the residential meter and it appears I can't separate the two .

Regards,

Paul Diglio

Just off the top of my hrad. Separate DHW loops?

Does anyone know a way to model one gas-fired DWH per thermal zone.  I have a model with one in each apartment.

Thank you,
