Hi,
I'm investigating to incorporate an integrated heat pump (electrical) in a Air Handling Unit. The AHU heating and cooling coils are connected to a borehole field through heat pumps. The integrated heat pump would start in case of the boreholes are exhausted and need time to generate: It is a back up system. I'm modelling this system on DesignBuilder. Do you have an idea how I can incorporate it?
Thanks in advance,
Nassim
