Hi All,

I am trying to model a building that is served by radiant panels and a DOAS. The CHW/HW for the radiant panels is provided by a water-to-water heat pump. The DOAS has a water-to-air heat pump (with a HW reheat coil tied to the radiant HW loop). Both heat pumps are tied to a condenser loop that rejects/extracts heats from a nearby river via a heat exchanger (the daily/monthly/weekly avg temps of which are known). Both heat pumps also have a waterside economizer, so that the condenser water can be used when there's a call for cooling and the loop is cold enough.

I am a little lost as to how to set up the water-to-air heat pump as a component within the air loop; the only option i can see is to put a water-to-air heat pump within a zone as terminal equipment... is there any way of implementing such a device on the air loop level?

Thanks

Ajit
