摘要
There are described a defrosting method and apparatus for a freezer- refrigerator using a GA-fuzzy theory.PPA defrosting method for a freezer-refrigerator using a GA-fuzzy theory of the present invention comprises the step of: inputting reference learning data by experiment and actual data to a microcomputer; calculating each frost- quantity on evaporators for a freezing room and a cold-storage room from the input data; inferring each defrosting period for the freezing room and cold-storage room from each frost-quantity on the evaporators for the freezing room and cold-storage room by using a GA- fuzzy theory so that the defrosting periods can be synchronized with each other; and controlling a defrosting heater depending on each defrosting period. PPAccording to the present invention, a freezer- refrigerator can be defrosted by calculating each defrosting period of the freezing room and cold-storage room 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`.
