Neil, Here is the path to the most current version associated with the 2022 release.
https://svn.code.sf.net/p/cbecc-com/code/branches/CBECC-Com_MFamRestructure/Documentation/T24N/Appendix_5.7_PerformanceCurves.xlsx
I can't think of much that has changed since 2016, and it does not contain curves for some of the newer E+ equipment, like A2WHPs. Also, this only summarizes curves used for the E+ sim engine, and currently does not include curves that are hard-coded or used in the CSE sim engine. Also, small (<65KBtu/hr) AC/HP cooling EIRfT performance curves are now curve maps based on input SEER/EER, as described in the NACM.
The spreadsheet is ultimately used to generate the text for the Library_PerformanceCurves-T24N.rule file, and the .rule file is what is used in the program, so ultimately the text file is the "final" reference.
Hope this helps, David
