A SENSITIVITY STUDY OF THE REFRIGERANT PROPERTY UNCERTAINTIES ON THE VAPOUR COMPRESSION CYCLE.

Author(s) : DOMANSKI P. A., DIDION D. A.

Summary

THE PAPER PRESENTS A SENSITIVITY STUDY OF A VAPOUR COMPRESSION CYCLE IN THE FORM OF A HEAT PUMP OPERATING IN THE COOLING MODE. SIMULATION RUNS WERE MADE FOR DIFFERENT PARAMETRIC VALUES AND THE CAPACITY AND POWER INPUT WERE COMPARED WITH RESULTS OF A RUN USING AN UNCHANGED VALUE OF THE PARAMETERS. THE EFFECTS ON EVAPORATOR AND CONDENSER PRESSURES AND REFRIGERANT MASS FLOW RATE ARE GIVEN. THE INDEPENDENT VARIABLES INCLUDE THERMODYNAMIC AND TRANSPORT PROPERTIES, AS WELL AS THE REFRIGERANT FLOW HEAT TRANSFERAND PRESSURE DROP COEFFICIENTS. THOSE WHICH HAD THE MOST EFFECT ON SYSTEM PERFORMANCE WERE LIQUID TRANSPORT PROPERTIES, EVAPORATIVE HEAT TRANSFER COEFFICIENT AND VAPOUR DENSITY.
