[Achim Geissler]

Dear Miguel

still not quite sure what system you mean. What is "the simplest HVAC system"? All three (H, V, AC)? Just one? Have you looked at the available "Air Source Heat Pump connected to WCH system"? What is your source / sink?

How is your heat pump connected to the building? Via a/the Ventilation system? Via the WCH? Possibly you can set up a plant that fits your needs with "only" the actual heat pump (between whatever the source/sink is) is missing. Thereby, you can possibly model any effects you need (as "maximum complexity example" maybe look at the exemplar "sports_cen" found in training/chp) and keep post-processing to a minimum.

Best
Achim

In controls, you typically enter the maximum power available (at the receiving end, that is). Simulation results will give you the fraction used at each time step. From this, it should be straightforward to calculated your electricity needs using the COP as a post-process step. No?

In the control module can only put the maximum power heating and cooling and in this case can never put the COP of the machine.
