Abstract

There are described a defrosting method and apparatus of a refrigerator using a GA-fuzzy theory. The defrosting method comprises the steps of: inputting reference learning data by experiment and actual data to a microcomputer; inferring frost-quantity on an evaporator from the input data by using the GA-fuzzy theory; calculating a defrosting period from the frost amount; and controlling a defrosting heater depending on said defrosting period. According to the present invention, a refrigerator can be defrosted by calculating the frost-quantity on the evaporator with precision and accuracy even at an input function which has many inflexion points and is impossible to differentiate, which is different from the conventional defrosting method using the crisp's logical algorithm consisting of `0` and `1`.
