about: Delta of temperature in Pinch algorithm
Is your feature request related to a problem? Please describe.
Misunderstanding in pinch algorithm, the minimal temperature difference is a chosen parameter depending on economic factor (OFEN report). In our case, the choice is made with a wrong heuristic which won't work each time. See example 2 in tests, an error is raised but shouldn't, it is just the guessed DTmin which is wrong.
Describe the solution you'd like
Enable to choose a DTmin in the GUI and to change it to check its impact on energy saving possibility. Use the DTmin currently guessed as suggested starting value. Update documentation.
Describe alternatives you've considered
Another solution could be to run lots of tests of DTmin and to select the one that includes the best energy recovery (minimal hot and cold utility).
