A numerical investigation of a diffusion-absorption refrigeration cycle operating with the binary propylene-octane.

Author(s) : SOLI N.

Summary

We propose in this work a numerical investigation of a diffusion-absorption refrigeration cycle working with a hydrocarbon mixture. It is about a machine of low refrigerating power (300 W). We used a cooling medium temperature in the condenser and absorber at 35° C .Helium is used as an inert gas. The total pressure of operation is about 17.5 bars.
A modeling on suitable software was made for the system. The mixture of propylene/octane was considered. The validation of our model was made by comparison with the results obtained by the model of H. Dardour and al. for the binary propane/nonane.
Generally, we can conclude that the mixture of hydrocarbon proposed is a rather promising refrigerant as for the technical advantages which it offer, such as the use potential of a heat source at a temperature not exceeding 150°C.
