Hi All:

I would like to ask how to model a heat recovery run around loop.
Exhaust air from four air handlers passes over a air to water coil, and
the heat recovered to the water loop is sent to the preheat coils of the
four air handlers. Keep in mind I have limited experience in the
detailed interface.

My first guess is that I would have to create an air to water coil.
Now, how do I connect the exhaust air stream from the four air
handlers... do I set an exhaust amount to each zone??
Then would I create a HW loop connecting the energy recovery coil to the
four pre-heat coils??

thanks,
