I have a building that is predominantly VAV with UFAD using a boiler/chiller plant. However, one portion of the building is residential which we would like to use WLHP's for. I would like to use purchased hot water (geothermal at 110 deg from City) and the chilled water from the building plant to maintain the WLHP Loop between 60 and 90 deg.

Any ideas on how to model this?

Also, I've been a bit confused on how eQuest uses PVVT systems to represent the air-side of WLHP systems. Any references or resources anyone has that explains the theory behind this would be greatly appreciated.

Thanks,

Dan Russell, EIT
