HI again,

I'm trying to model a VRF system using an infinitely efficient heat pump
(so as to bring the cooling/heating loads to the systems level and then
adjust with part-load performance at a post-processing stage).

The problem with this approach is that the heat pump units are using the
compressors even when they are just transferring heat within the loop
without input from the central plant, while the VRF system recovers heat
without any power input. Would using a COP of 10,000 take care of this as
this would result in an infinitely efficient compressor? How will the
condenser energy consumption be incorporated?

Thanks again,
