In general, the parameters that should be included in an absorption systems is the tube diameter and thickness. other parameters can be included based on the application that your system is used for such as different refrigerants and the produced cooling power.

Thank you very much for your suggestions. I realised that i did not give the necessary explanations about the parameters of design. I would like to know, what is the range of temperatures for driving a single-effect LiBr/H2O absorption system.

This is the first time that I am using this web page, and I did not see your answer. My apologise.
