Wall heat storage in displacement compressors

摘要: The role of cyclic heat transfer between the walls a piston/cylinder and gas being compressed is investigated from point view thermodynamic performance. It shown that adiabatic efficiency depends directly on amount transferred which in turn operating parameters as well material compressor constructed. for good high pressure ratio performance, cylinder head, piston head upper section must be built with materials low thermal conductivity. Candidate are found ceramic family silicon compounds, among others.
