Summary

THE RESULTS OF A PROLONGED INVESTIGATION OF THE INFLUENCE OF THE LUBRICATING OIL SHELL CLAVUS 68 ON THE PERFORMANCE OF AN R12-BASED REFRIGERATION-HEAT PUMP SYSTEM ARE PRESENTED. THE STRATEGY IS DISCUSSED FOR DECIDING IF A GIVEN SERIES OF DATA COLLECTED AT 10 S INTERVALS ADEQUATELY REPRESENTS THE CHOSEN EXPERIMENTAL CONDITIONS AND RESULTS ARE PRESENTED UNDER BOTH TRANSIENT AND STEADY STATE CONDITIONS. THE EFFECTS OF OIL ON EVAPORATOR CAPACITY, COP, HEAT TRANSFER RATES, EVAPORATOR OUTLET SUPERHEAT STABILITY, REFRIGERANT MASS FLOW RATE, EVAPORATOR PRESSURE DROP AND COMPRESSOR DISCHARGE TEMPERATURE ARE DISCUSSED, AND THE EXPERIMENTAL RESULTS ARE COMPARED WITH A THEORETICAL ANALYSIS. IT IS SHOWN THAT IT IS POSSIBLE FOR BOTH THE EVAPORATOR AND CONDENSER TO ACT AS HEAT REJECTORS.
