Help a fellow engineer with his thesis
hello
i am currently working on my thesis and i am in need of a little help.
I am making a Rankine Cycle and i am using as fluids the following:
R134a - R290 (propane) - R600 (n-butane) - R141b - R142b - RC318 - R218
First question: It there a big problem with me choosing R600 instead of R600a? The net is full of data for R600a but next to none for R600
Second question: I am currently trying to find data for my chosen fluids. These data are their Ozone Depletion Potential ( ODP) , Global Warming Potential ( GWP) and their toxicity levels ( A1-A3,B1-B3). Unfortunately i have only found what i was looking for only for R134a,R141b & R142b.
It would be a great deal of help to point me to where i can find the rest.
Note that i am going to need a link and not just a reply since i need to include it in the references.
Thirdly: The Rankine cycle will work between the values of 20-90 Celsius to produce electrical energy. If you have any recommendations for other fluids i will glaly hear them
