THE INFLUENCE OF THE REFRIGERANT CHARGE ON THE FUNCTIONING OF SMALL REFRIGERATING APPLIANCES.

Author(s) : KUIJPERS L. J. M., JANSSEN M. J. P., VERBOVEN P. J. M.

Summary

THE AMBIENT TEMPERATURE DETERMINES THE CONDENSER TEMPERATURE AND THE HEAT LOAD OF THE EVAPORATOR, WHICH, IN TURN, DETERMINE THE OPTIMUM AMOUNT OF CHARGE. A VOID FRACTION CORRELATION FOR THE DESCRIPTION OF TWO-PHASE FLOW CONDITIONSIS PRESENTED AND COMPARED WITH MEASUREMENTS. THIS VOID FRACTION MODEL IS THEN USED IN A STEADY-STATE NUMERICAL ANALYSIS OF AN APPLIANCE. THE CAPACITY OF THE CAPILLARY TUBE AND THE CONTROL STRATEGY ALSO PROVE TO BE IMPORTANT PARAMETERS FOR THE DETERMINATION OF THE OPTIMUM REFRIGERANT CHARGE. RECOMMENDATIONS FOR COMPONENTS ARE GIVEN FOR THE CASE WHERE THE APPLIANCE HAS TO FUNCTION WELL OVER A BROAD AMBIENT TEMPERATURE RANGE WITH A FIXED REFRIGERANT CHARGE.
