2016-09-15 15:05:54 -0500 | commented answer | Openstudio Air-Cooled Chiller Default Curve Thanks a lot, Matt! Both of those things are good to know about. It isn't that difficult to put in your curves manually, but it is nice to have a measure to do it. |
2016-09-15 14:49:27 -0500 | commented answer | Openstudio Air-Cooled Chiller Default Curve Thanks a lot for the response, Andrew! I'll add it to the feedback page. I think you're right that it's a mistake. It's not that the specific curve is particularly important, but it is important that if there's an object built into OpenStudio called "air-cooled chiller," by default it behaves at least somewhat like a generic air-cooled chiller. |
2016-09-12 16:31:25 -0500 | asked a question | Openstudio Air-Cooled Chiller Default Curve This seems related to this post: https://unmethours.com/question/10240... but I think it's different enough to warrant its own question. The gist is that it seems that the default air-cooled chiller EIR-fPLR chiller curve doesn't seem to be representative of most chillers, or any reasonable default. The EIR-fPLR curve assigned to an air-cooled chiller when you pull it out of the library has the following coefficients: a 1.6853121, b -0.9993443, c 0.3140322, This curve looks nothing like any of the curves in the EnergyPlus Air-Cooled chiller library or any of the Comnet or DOE-2 default curves. According to this curve, chiller energy usage will actually increase as PLR decreases, which is obviously incorrect. Seems like there must be a reference off somewhere? The CAPFT and EIRFT default curves look very similar to those of the other curves I can find. I'm using OS version 1.12.0, but looking at an old version of the library from 1.11.0, I think the default EIRfPLR curve is the same. Is this a mistake in the library? I'm attaching chart graph comparing the EIRfPLR curve evaluated compared to the DOE-2 and Comnet default curves that Julien Marrec posted in the question linked above. As you can see, they're pretty drastically different! |

2016-07-22 14:14:45 -0500 | asked a question | Openstudio 1.11.0 model.sqlfile Method Returns 0 Let me start by saying I'm pretty new to Openstudio. I've been having an issue that keeps cropping up - when running simulations and measures, it seems that I frequently get warnings or errors whenever the script I'm running attempts to look up data that's supposed to be passed back from energyplus either from the current run or a previous run (mostly zone or other equipment sizing data). It seems that the root of the issue is that in every model I've created, the "model.sqlfile" method returns 0, and so there's no database from which to look up information. When running simulations, the software seems to recover from this by calculating whatever it's looking for on its own, but some measures (specifically the "Create Performance Rating Method Baseline Building" measure from the standards library) fail without that sql file. Any tips on what to do here? Is there some setting that I'm missing? |
