heat_exchanger with set_massflow

[ladderup]

In houses a heat_exchanger can controle the massflow depanding on the demand.
In the create_heat_exchanger() only the extracted qext_w can be set. The massflow is the result.

Setting the heat_exchanger massflow to zero will result in cooling of the district-heating-network in particuliere spots.
The cold spots can be fixed with a bypass.

I guess this can all be achieved with pipes, valves, pumps and heat_exchangers but still. A few more functions in a heat_exchanger could be nice.

Hallo,

Thanks for this comment. You are right that the heat exchanger functionalities are currently limited. We started to work on an improved version some time ago. Unfortunately, we have a also a strong focus on new features for simulating gas networks, which leads to a delay of new or improved components.
