I have been unable to get a two-stage Transcritical CO2 system to even open up in the OS app. My approach has been to create the standard refrigeration system objects in the OS app, with compressors and condenser objects. Then, manually edit the .osm text file to replace the standard refrigeration objects with transcritical objects, replace the condenser with a gas cooler object, and add transcritical compressor coefficients for the high pressure compressors. After making these changes, I have not been able to reopen the model file in the OS app. The error continues to say either field 3 or field 4 of the transcritical system has an incorrect data type:
The collection is INVALID at strictness level 'Draft', because of the errors: Field level data error of type DataType . Error is in an object of type 'OS:Refrigeration:TranscriticalSystem', named 'Rack A1B1 TransRefrigSys', in field 4. Additional information about the error type: field-level data is of an incorrect type.
