How to model an underslab glycol loop in EnergyPlus?

Is there a way in EnergyPlus to model an underslab glycol loop that receives waste heat from a refrigeration system? A heat exchanger between the refrigeration system and the glycol loop would take waste heat from the refrigeration system to heat up the glycol loop. The glycol loop would flow through the slab construction in the refrigerated zones. I can't find a way to connect a plant loop or a heat exchanger to any of the components of the refrigeration system. I am modeling a refrigerated warehouse with an evaporative cooled condenser, a compressor rack, and several air-chiller objects.

Yes, this should be possible although it is fairly advanced. You would need to use the more detailed refrigeration modeling available with the Refrigeration:System input object. Then the Refrigeration:Condenser:WaterCooled input object would connect refrigeration to the plant loop.
