<p>Eng. Sayed,</p>
<p> I usually build up this kind of air handler from its component
pieces (some combination of a fan, a heating coil, the DX cooling
coil and perhaps an enthalpy wheel). A DX coil can be modeled
using a performance map that gives COP as a function of the air
conditions entering the evaporator and the condenser. There are a
few different components TESS HVAC library (in the "air handler
components" folder).</p>
<p>kind regards,</p>
<p> David</p>
