I have a large hospital model with a system to serve the
space requirements for the kitchen, serving area, dish washing area, and
the surrounding spaces. The kitchen, serving area, and dish washing
area have exhaust hoods that don't run all the time, and there is
a separate DOAS system that supplies 100% OA to just the spaces with hoods
for make-up air. What is the best way to model these two systems serving
just those spaces? Also, the DOAS make-up unit tracks with the exhaust
flow depending on which hoods are on at any given time. Thanks
