<div>Carol,</div>
<div> Thanks for pondering on my problem. I have no heat exchanger in the MAU system. There is just MAU with Cooling coil and It provides the ventilation to different Heat pumps through the system.</div>
<div> </div>
<div>Let me know if it unclear.</div>
<div> </div>
<div>Regards,</div>

There's an answer for that. If it provides OA than can vary, there's a different answer for that.<br>
<br>Let us know.,<br>Carol<br>

<div>Hello All,</div>
<div> I am modelling a MAU system providing the ventilation air to the ~ 300 heat pumps located through out a 14 -storied building. The MAU has a cooling coil and a heating coil and so It initially tempers the outside air. The MAU air is even more tempered by heat pumps to maintain the space temperatures in the zones. </div>
<div> </div>
<div>How can I model this system - combination of a MAU unit and heat pumps?. This is a case of cascading HVAC systems. Any comments/help on this modelling case would be appreciated.</div>
<div> </div>
<div>Thanks,</div>
