REFRIGERANT CHARGE IN SMALL APPLIANCES: INFLUENCE OF THE CAPILLARY/SUCTION LINE HEAT EXCHANGER.

Author(s) : KUIJPERS L., JANSSEN M., WIT J. de

Summary

THE INFLUENCE OF THE REFRIGERANT CHARGE AND CAPILLARY TUBE CAPACITY ON THE PERFORMANCE OF A CONTINUOUSLY CONTROLLED REFRIGERATING APPLIANCE IS DESCRIBED. MEASUREMENTS AND CALCULATIONS OF THE NECESSARY REFRIGERANT CHARGE HAVE BEEN PERFORMED FOR A CONFIGURATION WITHOUT INTERNAL HEAT EXCHANGER. A VOID FRACTION MODEL IS SELECTED FROM A COMPARISON OF THE RESULTS. OPTIMIZATION OF THE CAPILLARY SHOULD BE PREFERRED FOR CONTROL OVER A WIDE AMBIENT RANGE IF A FIXED REFRIGERANT CHARGE IS APPLIED WITHOUT USING AN INTERNAL HEAT EXCHANGER. THE NECESSITY OF A PRECISEOPTIMIZATION OF THE CAPILLARY TUBE IS NUMERICALLY INVESTIGATED ASSUMING THAT THE HEAT EXCHANGER IS IMPLEMENTED IN THE SYSTEM.
