The project is located in NYC, and the DOB has already been approved the design. The intent is to recover the conditioned air from apartment and use it to preheat the 100% OA that will be supplied to Corridors using heat recovery wheel.<br>

I have a typical situation for DOAS system that serves fresh
air (100% OA) to corridor spaces in multifamily building. The
DOAS unit is equiped with heat recovery wheel, and uses the
exhaust air from apartments, i.e. exhaust from bathroom and
kitchen rather than return air from corridor itself. How would
i model the system that uses recovered heat from one system to
another in the eQUEST.<br>
<br>
Thanks in advance for your help.<br>
