In the first report, evaluation of refrigerant vapor-liquid two-phase flow using the test sections of single-row model simulating the refrigerator evaporator was examined under heating condition, and basic flow characteristics was clarified. In this report, evaluation of refrigerant flow under same heating condition using the test section of staggered arrangement, two-rows and inner-grooved tube model was carried out. It was made clear, in the staggered arrangement and inner-grooved tube model, refrigerant flow was same characteristics as results of first report, but process time of the change became short. In the two-rows tube model, refrigerant flow pattern was different from the row connected to an accumulator and the other row. Furthermore, in the two-rows fin-tube model, in both rows flow pattern was different, but change of tube wall temperature was similar by the heat conduction of fin.抄録：This study focuses on characteristics of refrigerant flow and heat transfer inside the evaporator tube to improve performance of defrosting for refrigerator.
