Abstract:
In an operation control method for a refrigerator which stores an operation information of the refrigerator into an information storage part, and performs a cooling operation and a defrosting operation according to the stored operation information, the operation control method for a refrigerator, comprising the steps of:(a) reading an operation information stored in the information storage part if a power-supply is applied to the refrigerator;(b) determining whether or not the operation information includes a compartment set temperature information and an accumulated information of a compressor operation time;(c) if the compartment set temperature information and the accumulated information of the compressor operation time are in the (b), automatically setting an operation mode according to the compartment set temperature information, and detecting a compartment temperature fo the refrigerator and an evaporator surface temperature;(d) determining whether the compartment temperature is lower than a predetermined compartment temperature to determine a power-failure of a long time, or the evaporator surface temperature is lower than a predetermined surface temperature to determine a power-failure of a long time;(e) if the compartment temperature is lower than the predetermined compartment temperature or the evaporator surface temperature is lower than the predetermined surface temperature in the step (d), accumulating an compressor operation time in addition to the compressor operation time stored in the information storage part; and(f) if the compartment temperature is not lower than the predetermined compartment temperature and the evaporator surface temperature is not lower than the predetermined surface temperature in the step (d), deleting the compressor operation time accumulation information stored in the information storage part, and newly accumulating a compressor operation time.
