Résumé

The performance parameters and behaviour of a forced convection dual evaporator household refrigerator were studied. The design tested uses a serial connection where the refrigerant flows through the fresh food evaporator and then through the freezer evaporator without a pressure drop between the evaporators. Control of the fresh food cabinet air temperature was achieved by cycling the fan off and on during operation. Performance tests were conducted using a prototype refrigerator at several different charges and two different fan cycle length settings. This fan cycling affected both the performance of the prototype and the charge distribution inside the system. The length of the fan cycle is a significant factor in determining the size of charge and the refrigerant state at the evaporator exit. The fan cycle length and charge must be chosen so that the evaporator exit is neither excessively superheated nor two-phase at any point during the fan cycle.
