2021-11-10 16:26:33 -0500 | marked best answer | 3242 Severe errors - Controller error for controller=cooling water coil I am unable to tweak this error which I got while running for full year simulation. I have set one chiller feed to TES and TES to the Colling coil in the secondary Chilled water loop. I have set the Controller for water coil as The error I am getting is While I am still trying to understand the SimHVAC iteration fix based on the suggestions here https://unmethours.com/question/17449...

2020-05-09 17:07:06 -0500 | marked best answer | Chiller selection/modification for Ice storage I am using the chillers provided by default for the CHILLER:ELECTRIC:REFORMULATEDEIR as Bicubic:ReformEIRChiller Carrier 19XR 1259kW/6.26COP/Vanes EIRFPLR, Biquadratic:WC Screw Default 90.1-2004 Cap_fT Biquadratic:WC Screw Default 90.1-2004 EIR_fT Minimum temperature from the chiller outlet should be as low as (-)10 oC, The range of the leaving CW Temp is set 0 to 20. Is it safe to modify the range to meet the low temperature and get valid performance? The Included Chillers.idf have the curves with even narrower temperature range with the minimum around 4 oC. I am getting some errors and I suspect they might be due to this limitation. (more) |

2018-05-02 10:45:25 -0500 | marked best answer | OpenStudio Crashes while selecting plant loop I noticed this on multiple OSM files recently that openstudio just crashes when I select to open the plant loop or condenser loop. Earlier I had to abandon and start with the new OSM file because of this issue. But even this OSM file started crashing.
