The Munters unit I am using is the Drycool Dehumidification System. It is a 100% OA unit that I am using to feed several water source heat pumps room neutral air thus lowering the load on the heat pumps. Outside air enters the Munters unit and passes through the top half of an Enthalpy wheel. Return air from the space passes through the bottom of the wheel exchanging heat from one stream to the other. The outside air is then pre-cooled with a DX coil then passes through a desiccant wheel. The DH wheel is regenerated with the same return air stream as before after is has passes through a row of coils with heat from the compressors. The supply air is now 76? 33% RH. That air is then ducted to return plenums attached to each heat pump.

I know that I can use the "Outside air from system" option to supply the air to the heat pumps but I have yet to find a way to accurately model this unit, specifically the enthalpy wheel's position in the system and the desiccant wheel's regeneration source (waste heat from the compressor). Admittedly I a new to equest but I have spent a considerable amount of time on the conundrum. Any help would be greatly appreciated.
