Add pipe manufacturer's data for single pipes #31

Closed bramvdh91 closed 7 years ago

bramvdh91 commented 8 years ago

Add records that facilitate easy thermal resistance calculations for single (buried) pipes. Example of product sheet: http://www.isoplus-pipes.com/fileadmin/data/downloads/documents/germany/manuals/chapter_2_web.pdf

Data added. Needs to be tested with the validation example (however, this seems to be a non-standard pipe comparing to the IsoPlus catalogue).

I have updated this branch with the current "master" branch in a0446b8. @marcusfuchs , since you are using the models in other case studies too, could you check if this implementation works? I have experienced that for the validation cases, the pipe dimensions do not correspond to regularly manufactured pipes. This can be overridden in the pipe's parameters, but the current standard calculation of the pipe's R and C values relies on standard data. Before merging this branch, I think it is good to reconsider where and how the resistance value is calculated. Maybe it is interesting to give the user the choice to either enter the pipe's resistance value directly, or to specify the pipe dimensions/insulation parameters and leave the resistance to be calculated as a final parameter.
