| 摘要 |
The invention provides a method of defrosting a frost load accumulated on an evaporator, the method comprising the steps of: performing a normal mode for controlling ON-OFF operations of the compressor; sensing a temperature of the evaporator, comparing the sensed temperature with a first preset temperature to thereby determine a significant amount of frost; if the sensed temperature is less than the first preset temperature, removing the frost by activating the fan and the heater for a predetermined duration; determining whether or not the fan should be activated during the defrost mode, by sensing and comparing temperatures outside/inside the refrigerator, and a total number of instances of a refrigerator door opening and closing; checking whether or not the duration has elapsed, and if the duration has not elapsed, continuously activating the heater; and de-activating the heater if the duration has elapsed and performing the normal mode.
