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 McNally
