DEVELOPMENT OF A RECTIFYING CIRCUIT WITH MIXED REFRIGERANTS.

Author(s) : YOSHIDA Y.

Summary

THE AUTHORS HAVE DEVELOPED CALCULATION PROGRAMS TO EVALUATE THE THERMODYNAMIC PROPERTIES OF MIXTURES OF REFRIGERANTS, FROM THOSE OF THE PURE COMPONENTS. THE MIXTURE R22-R13B1 WAS FOUND TO BE EXPERIMENTALLY PROMISING FOR HEAT PUMPS. THEY HAVE DEVELOPED A SMALL RECTIFIER. IN THE INITIAL REFRIGERATING CIRCUIT OF THE AIR-AIR HEAT PUMP, THE BOTTOM OF THE RECTIFIER IS LINKED TO THE CONDENSER AND TO THE EVAPORATOR BY CAPILLARY TUBES IN PARALLEL WITH THE EXPANSION VALVE. WHEN THE EXPANSION VALVE IS OPENED, IT OPERATES WITH A LOAD OF MIXED REFRIGERANTS, WHICH INCREASES THE THERMAL CAPACITY. WHEN IT IS CLOSED, THE FLOW OF THE REFRIGERANT MIXTURE ENTERS THE RECTIFIER AND THE RECTIFICATION BEGINS WITH THE VAPOURS GENERATED IN THE CAPILLARY TUBE WITHOUT HEATING DEVICES.
