Résumé

In this paper, the solid–liquid equilibrium of the binary system containing difluoromethane (R32) and trans -1,3,3,3-tetrafluoropropene (R1234ze(E)) was experimentally evaluated. An experimental setup was used to measure 20 different compositions of the binary system in the temperature range from 168.2 K to 132.00 K. The studied binary system showed an eutectic point which was estimated at the temperature of 132.00 K. The results for the solid–liquid equilibrium of the studied system showed a general agreement with the prediction provided by the Schröder equation, showing deviations generally within 2–3 K. In addition, in order to test the validity of the experimental setup, the triple point temperatures of the components of the binary system and four well described refrigerants (namely R125, R152a, R143a, and R41) were measured. The experimental results for the pure refrigerants agreed with reliable values available in the literature.
