Summary

In order to determine how R22 alternatives react with alternative lubricants regarding stability, the performance and energy efficiency, oil return investigations with R22 and R407C were carried out with different lubricants. The condensation temperature rised to 40 °C and the minimum evaporation temperatures went down to -30 °C. Stability was ensured also with the insoluble refrigerant/oil mixture R407C/alkylbenzene-oil. The influence of the lubricant on the performance was shown.
