ASHRAE Handbook of HVAC Systems and Equipment Chapter 4 describes some of the air-side systems with diagrams.
These are more than just the Appendix G mapped system types, and you'll have to look at other chapters for the description of the primary heating and cooling systems...overall a great resource if you aren't familiar with some of the potential variations in configuration for air distribution systems.
Chapter 4 will be a great read for you if you aren't familiar with some of the older system types that are common in existing buildings, more so than for Appendix G which is focused on a few modern system types.
