Experimental investigation of a rolling piston compressor operated with a hydrocarbon refrigerant mixture.

Summary

Theoretical considerations indicate enhanced system performance of household appliances when using zeotropic mixtures compared to R134a. This paper describes the experimental investigation of the performance behavior of a rolling piston compressor used in a heat pump tumble dryer and operated with a zeotropic blend. The experimental investigations demonstrate the change in operation conditions and compressor performance of the substitute refrigerant in comparison with the hydrofluorocarbon R134a. The compressor is tested on a compressor test rig according to DIN EN 13771-1 to measure and determine power consumption, cooling resp. condensing capacity, pressure ratio and cycle temperatures. The measured data of the reference setup with R134a and the substitute setup with a hydrocarbon refrigerant mixture will be compared with each other for a better understanding of their influences under different operation conditions.
