Multiple combinations of performance parameters and adopted constructional designs may lead to substantial differences in thermal energy efficiency of heating surface and thus increase cost of the entire system.
The research on plain surfaces or tubes shows that the nucleate pool boiling heat transfer of a refrigerant/oil mixture is obviously affected by the oil concentration; at an oil concentration below 5%, oil slightly enhances or reduces the nucleate pool boiling heat transfer, depending on the heating surface structure (Mohrlok et al.
