Hello all,

Does anyone know of a method to model an air-source heat pump that uses the air handler exhaust stream rather than ambient air? The intent here would be to model an energy recovery that uses a heat pump (rather than a traditional HX) for energy recovery between the exhaust and supply streams. This is a lab building in climate zone 6 (central Vermont).

Any suggestions for workarounds or approximations are appreciated.

Thanks,
Ari
