A new control system of a household refrigerator-freezer.

Author(s) : LEE J., CHO K. Y., LEE K. T.

Summary

The paper presents the structure of the new system, the control scheme and its performance test results. In this system, the damper in the conventional refrigerator is replaced by an additional cooling fan. Thus, it uses two cooling fans: one (freezer-fan) is to provide cooled air for freezing compartment, and the other (refrigerator-fan) is for refrigerating compartment. Experimental results show improved performance of the new refrigerator over the conventional refrigerator. Among them is the lower fluctuation of the refrigerating-compartment temperature, which has a significant effect in lowering the refrigerating temperature and storing foods fresh longer. The air-defrosting by the use of the refrigerator-fan was proved to be an efficient method in saving the energy consumption during the defrosting cycle.
