[Equest-users] VRF/VRV PowerPoint on Modeling and water cooled VRV modeling!

[Jenny Zhang]

Dear all,
I am trying to model a water-cooled VRV using equest. When use the approach in the PowerPoint I have met several problems:
1) if select condenser loop/water cooled as condenser type and PVVT as airside system I feel uncertain to choose which one as the EIR curve. Is PVVT-Cool-EIR-Fewb&OAT suitable to be used in this situation? 
2) the system heating source is heat pump and condenser loop is WLHP with a boiler and cooling tower to realize water-cooled VRV(heating and cooling system), I find there are no space heating and very little energy rejection in the simulation result. The reason I guess maybe heating doesn't work. Anyone who has modeled a water-cooled VRV? I want to know what your method and how do you consider the model results with the real system?
Waiting for your responses! 

Jenny Z.

Can anyone repost the Powerpoint presentation about how to model VRV/VRF in eQuest again?  Thanks!!
