[BLDG-SIM] Loop-to-loop heat-pump in eQUEST

[Zhen Tian]

Hello all,
   
  From the help file of eQUEST, it seems that eQUEST 3.6 can model air-to-water heat pump, well-water-to-water heat-pump and loop-to-loop heat-pump.
   
  When I model from the DD Wizard, the only system type alowed for heat pump is DX system, which means there is no chilled water flow in the systems. So I have to find a new method.
   
  I built up a conventional system with water cooled, then I change the chiller type to loop-to-loop heat pump, then the program ask me for HW loop, HW loop pump and CW loop, I selected the HW loop to hot water loop and associated pump, but I can not select the condensor water loop as the CW loop. It asked me to choose from libarry, so I chosed from Default-CW, but the program give me the warning " the Default-CW is an imcompatible type".
   
  I tried other loop types, but on one works. Does anyone has successfully tried this loop-to-loop heat pump before? Or is there any direction for set this up in eQUEST?
   
  Any suggestion is hightly appreciated.
   
  Thanks.
   
  Regards,
   
  David
