Abstract

The present invention relates to an apparatus for controlling the progress of freezing and refrigerating cycles of a refrigerator, and in particular, having an evaporator for supplying cold air to a freezer compartment and a refrigerating compartment, respectively, to detect a temperature change of the freezer compartment and a refrigerating compartment to change the temperature of cold air evaporated from each evaporator. By doing so, the energy efficiency of the refrigerator is to be increased.

However, in the conventional refrigerator, the cold air of -18 ° C. or less generated in the evaporator is supplied to the refrigerating chamber 9, which should be maintained at + 3 ° C., since the freezer is also supplied to the refrigerating chamber with water.

Therefore, it is difficult to maintain the temperature of the refrigerating chamber 9 at + 3 ° C, and there is a problem in that unnecessary power is consumed to lower the temperature of the cold air supplied to the refrigerating chamber more than necessary.

The present invention is provided with an evaporator for supplying cold air to the freezer compartment and the freezer compartment in order to solve the conventional problems, it is possible to reduce the power consumption of the compressor by supplying the cold air by selecting each evaporator by the atrial valve, The temperature can be adjusted according to the set temperature, so that the temperature of the refrigerating compartment can be kept constant. The temperature of the cold air supplied to the refrigerating compartment and the freezing compartment can be changed to increase the energy efficiency.
