Hi,
I have been trying to simulate a unitary HVAC device with a
heat
recovery module. I am using the Compact:Unitary equipment
simulation.
The heat recovery option does not materially change the
energy use
results.
A one zone building with one rooftop unit is
my quick running test
model. The compact unitary part is given
below.
Am I missing something?
Regards,
Jim
