<p class="MsoNormal"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Can anyone suggest how to model correctly an air-to-air heat pump that supplies/return primary air to the terminal units(6 heat pumps per 800,000sf of all glass high-rise).
The terminal units are fan power boxed, parallel flow. The heat pump also operates in economizer and heat recovery modes.<o:p></o:p></span></p>
