[Equest-users] Heat Recovery Chiller

[Bikesh Dahal]

Unfortunately it is. So, how is this normally done. Use excel spreadsheet to calculate savings? Or is there a work around to it.

Heat recovery from chillers is a little tricky in eQUEST.  In order to recover heat, the condenser loop supply temperature must be higher than the heating loop return temperature.  Doing that typically increases the lift on the chiller increasing the electrical input energy.

You stated you couldn't recover to your reheat loop -- is it a secondary loop?  Unfortunately no primary equipment can be attached to secondary loops.

Hi Everyone,
I am working on a project where I have a heat recovery chiller that is recovering heat from IT room units in a hospital and then providing heat to VAV reheat systems for other spaces. I am trying to model this in  equest and not getting the desired result.

eQuest is not letting me connect to reheat loop. And when I connect it to my steam loop, I see no heating savings whereas I see increased cooling use.
Anyone has any ideas on how to model this properly?
