Abstract (english): In this paper heat transfer coefficients for film condensation of carbon dioxide under elevated pressures are presented. The examined pressure ranges from 16-30 bars with a constant mass flow of 12 kg/h CO₂. Therefore, a pilot plant for cryogenic liquefaction of CO₂ has been built. In the installed tube in tube condenser cooling media temperatures from -25 °C to -45 °C were used. During the experiment heat transfer coefficients between 4500 and 13000 W/(m2K) were determined. Afterwards the experimental data were compared to common correlations for film condensation. The aim was to prove whether the influence of the elevated pressure can be predicted. Finally, all correlations could predict the heat transfer under elevated pressures in a suitable manner, concerning the uncertainties in modeling and determination of heat transfer coefficients. Nevertheless not all correlations could predict the influence of elevated pressures equally well.
