[Equest-users] WTWHP with ERU 100% OA and WSHP

[Kathryn Kerns]

Crina, what I have done in the past that is similar is:
1. in the Wizard, model your DOAs as hydronic chilled water and hot water units and the rest of your units as WSHPs
2. in Detailed Edit, add a 2-pipe loop, a heat pump chiller, a ground source heat exchanger loop, and a lake/well ground source heat exchanger.
3. In Detailed Edit, convert the DOA coils to the 2 pipe loop and remove the chilled water and hot water system.
 
That should leave you with a WSHP system and a ground loop WTWHP system. If you want to attach the WTWHPs to the WSHP loop, look up the eQuest literature on the Heat Pump Chiller option and see if there is a way to do this.

Dear eQuest users, 

 

I am working on a project that has WSHP conditioning all my spaces  but I also have energy recovery units with 100% OA and the OA is conditioned by WTWHP's . 

Did anybody tried this kind of system before because each idea I have and tried to apply into eQuest does not work for me today. 

Any help is appreciated. 

Thank you.
