Development of the operating process computation model for a low-flow low-speed compressor working on the R134a freon

Expansion of the low-speed compressors application scope leads to a need to conduct experimental studies with the working fluids used in the refrigeration equipment for subsequent creation of the computation models. The paper presents results of the experimental studies in organizing an operating process of the low-speed compressor stage with the R134a freon compression. Work was carried out to adapt the existing mathematical model of computing operating processes of the low-speed compressor stages working on the R134a freon. The obtained refined equation for the heat transfer coefficient on the working chamber inner surface would allow future theoretical studies of the low-speed compressors with such working fluid.
