The cooling system that I'm going to model can be considered as made by the following parts (active cooling):
1. ground heat exchangers
2. chillers
3. chilled glycol/water loop (pipes between the chillers and a heat exchanger, having in the middle two inertial tanks)
4. chilled water loop (pipes from the heat exchanger towards radiant floors and vice versa).
This is the "active cooling mode", but when the cooling loads are low the system can work in "passive cooling mode", i.e. the chillers are bypassed (part 1. "ground heat exchangers" is directly connected with part 3. "glycol/water loop", which in this way is cooled passively by the ground).
By the way, during the winter season the chillers work as heat pumps.
Any advice to model such a system, please? Do you know if there are examples available (e.g. in the ExampleFiles folder)?
With Regards
Francesco Passerini
