Summary

One of the main practical problem of creating low-temperature equipment based on real Joule-Thomson refrigerators operating mixed refrigerant is the difficulty in determining charge composition. The existing methods in the literature mainly solve the problem of determining and correcting the theoretical values of the mixed refrigerant component mass concentrations in certain scheme of
refrigerator at steady state operating mode due to their changing in relation to charged. This article represents approach of experimental approving of developed numerical method. The method allows determining mixed refrigerant temperature distribution along working cycle of refrigerator and composition of refrigerant charge with given geometry of refrigeration circuit and composition of circulating mixed refrigerant. Practical value of the method is ability to determine charge of refrigerant for specified refrigeration circuit, as consequence, reducing test duration of developed equipment. Developed test bench for suggested method approving is presented.
