I was asked what influences an engineers decision over design conditions,
and after looking for some textural support in the books, i could not find
anything to give guidance over when to use 0.4/1/2 or 99/99.6 % design
conditions. Does anyone know if this text exists in the ASHRAE books and if
so which chapter? I also looked into ASHRAE 90.1, but that only addresses
efficiencies of equipment and not the design conditions/capacity
calculations.
Thanks in advance,
