For the two-circuit refrigerator with parallel evaporators，refrigerating cabinet and freezing cabinet could not get cooling capacity at the same time. This will lead to the increase in compressor-on time due to the fact that the compressor shuts down as the counterpart cut-out temperature in the freezing cabinet is reached. The dynamic characteristics of a parallel-evaporators refrigerator with short-cycle switching control were studied experimentally. Results showed that the refrigerant stored in the freezing-evaporator was immigrated gradually to refrigerating- evaporator due to pumping action of compressor after a startup. The capacity loss of the refrigerating evaporator due to the refrigerant migration decreased from 33.9% to 5.2%. In addition， the temperature of the freezer-sensor decreased from -16.5 ℃ to -17.8 ℃ in the first six short-cycles，but only decreased by about 0.3 ℃ in the next five short-cycles. The short-cycle switching control strategy can decrease the temperature in both refrigerating cabinet and freezing cabinet. However， the refrigerating-run time will be extended at the same time. These two factors should be comprehensive considered to make the compressor-on time shortest.
