Investigation of the vapour liquid equilibrium behaviour of blends comprising R125, R134a and R600 or R600a.

Author(s) : ROBERTS N. A., JAWAD S. H.

Summary

Apart of R407C and R410A, R417A is a third alternative emerging as a candidate to replace R22, comprising R125, R134a and R600. In the development of this blend it has been found that there is a severe lack of documented data concerning the behaviour of mixtures of R125, R134a with R600 or R600a. This lack of data means that predictive tools such as REFPROP are unable to give reliable results. The paper details some initial vapour liquid equilibrium measurements made for the R600 and R600a binary mixtures with R125 and R134a and provides binary interaction parameters that may be used with the REFPROP software.
