Summary

Theoretical considerations indicate enhanced system performance of household appliances by using zeotropic mixtures compared to R-134a. This paper describes the experimental investigation of the performance of a rolling piston compressor used in a heat pump tumble dryer and operated with a low GWP zeotropic blend containing a natural refrigerant. The experimental investigations show the change in operation conditions and compressor performance of the drop-in refrigerant in comparison to the hydrofluorocarbon R-134a. The compressor is tested on a compressor test bench according to DIN EN 13771-1 in order to measure and evaluate the power consumption, the refrigeration and condensing capacity, the pressure ratio and the temperatures at different points of state of the cycle. The measured data of the reference setup with R-134a and the drop-in setup with a zeotropic refrigerant mixture are be compared for a better understanding of their influences under different operation conditions.
