Summary

WITH A TEST, ON A CALORIMETRIC TEST RIG, OF A HERMETIC COMPRESSOR AND OF A FREEZER WITH THE SAME COMPRESSOR OPERATING WITH R502 AND WITH THE NON-AZEOTROPIC R502-R113 MIXTURE,THE AUTHORS ESTABLISHED THAT THE USE OF THIS MIXTURE FACILITATES THE COOLING OF THE ELECTRIC MOTOR COIL, REDUCES THE SUPERHEATING OF ASPIRATED VAPOURS AND, CONSEQUENTLY, IMPROVES THE THERMAL AND ENERGETIC CHARACTERISTICS OF THE COMPRESSOR AND THE REFRIGERATOR. THE OPTIMUM CONCENTRATION OF R113 IN THE MIXTURE IS 10 TO 15%.
