THERMODYNAMIC COMPARISON OF REFRIGERANTS FOR USE IN HEAT PUMPS AND REFRIGERATING MACHINES: IMPACT OF SUBCOOLING AND SUCTION OVERHEAT.

[In German. / En allemand.]

Type of article: Article

Summary

THE THEORETICAL COLD-STEAM MACHINE OPERATION IS USED AS A THEORETICAL REFERENCE PROCESS OF SINGLE-STAGE COLD-STEAM COMPRESSION REFRIGERATING MACHINES AND HEAT PUMPS. ITS RATINGS ARE SMALLER THAN IN THE CARNOT PROCESS IN CONFORMITYWITH QUALITY LEVELS FOR REFRIGERATING OR HEAT PUMP OPERATION. FOR R13B1, R502, R22, AMMONIA, R12, R114, R11 AND R113, THESE QUALITY LEVELS AND THE EFFECT OF SUBCOOLING AND SUCTION OVERHEAT OF REFRIGERANTS ON THE RATINGS AND VOLUMETRIC REFRIGERATING AND HEATING CAPACITIES OF THE THEORETICAL COLD-STEAM MACHINE OPERATION ARE DETERMINED AND PRESENTED FOR COMPARISONS. HINTS AT THE APPLICATION OF PARAMETERS TO THE REAL PROCESS COMPLETE THE STATEMENTS.
