How do Packaged Units control air temperature
(OP)
How is it possible to maintain constant supply air temperature when different heat loads are in the return air and you have a constant speed compressor? Many units only have 4 compressors for systems around 30 Tons. Is the trick to have multiple compressors so the supply air temp does not waiver too much? In chiller systems they have control valves to control the chilled water through the evap coil, while I am not aware of any control valves in a refrig loop. Is there something I am missing here, or does constant temperature mean sort of constant?

You just need to know your load and load profile and try and match your equipment as best you can.
