I have attached another picture above. Am I placing the "DisplayAdvancedReportVariables" in the BCL outputs? Also, I can now get the pump to show up in energy usage however it is only through hard sizing the rated flow rate and rated power consumption in the plant loop. This does not seem to be the correct way to approach the problem. |

| 2015-08-10 15:21:56 -0500 | commented answer | How do I troubleshoot a water-cooled condenser with no flow? Thank you for the response and feedback. Before I was auto sizing and getting 0 for mass flow through the inlet to the condenser. I have attempted hard sizing the condenser loop and I am still seeing 0 for the mass flow rate through the condenser loop, despite hard sizing the flow in the loop. I have attached screenshots to the original question. Any suggestions? Thank you very much for your help. |

Yes, I have a water cooled condenser on the Demand side and a pump, variable speed cooling tower and set point manager on the supply side. I have also taken a screen shot of the loop. Is there any way for me to post it for reference? Sorry, I am brand new to Unmet hours community. Thanks again. |

| 2015-08-07 15:26:37 -0500 | asked a question | How can I properly implement a water cooled condenser in OpenStudio? I am having issues running a proper model in OpenStudio with a water cooled condenser on the refrigeration loop. I have the water cooled condenser connected to a water plant loop, however, there is not flow within this water loop. Does anyone have any advice for troubleshooting this issue? Thank you very much. |

| 2015-08-06 18:11:57 -0500 | asked a question | How do I troubleshoot a water-cooled condenser with no flow? I am attempting to model a refrigeration cycle with a water cooled condenser but am having troubles. The system runs however the results show that there is no mass flow of water through the loop. It is a simple box building with 1 walk-in refrigeration case and 1 compressor. The model works with air-cooled condenser, but the water cooled condenser however does not show any water flow or pump power. I have also tries to plot pump power of the water loop and this also shows zero. I cannot seem to trouble shoot this system, any help or advice would be greatly appreciated.
