In SimAirServingZones::UpdateSysSizing, DesHeatCoilInTempTU is set for heating zones only using GetHeatingSATempForSizing (similar for humrat) here. In Fix VAV min flow frac > 1.0 and a bunch of termunitsizing issues related to multiple airloops #6338, for consistency with other blocks in UpdateSysSizing, I added a loop here over cooled zones for completeness, show here. But that caused large changes in reheat coil sizing across many files - maybe these are OK, but too much to review at this point, so the new block over cooled zones was removed.
PR6481 initially caused a bunch of new errr messages about table units conversions

These have been addressed in bb00e38 by switching to existing units strings, e.g. KGWATER/KGDRYAIR, but we might prefer to add some new units strings instead.

Need unit tests for both Std 62 and coil sizing report.

But that caused large changes in reheat coil sizing across many files - maybe these are OK, but too much to review at this point, so the new block over cooled zones was removed.Review diffs from system sizing refactor System sizing adjustments for Std 61.2 VRP - fix and refactor #6372 and fix here if needed.
Review diffs from new coil sizing report New Coil Sizing Reports #6454 and possibly reinstate or modify the lines that were reverted here which, BTW, were suspected of causing diffs but nothing changed after this commit. Also, see various comments from @rraustad in New Coil Sizing Reports #6454 .
