  • Defrost control apparatus and method for a refrigerating system
    Patent number: 5251454
    Abstract: A thermistor is mounted between the fins of an evaporator. The thermistor senses the temperature about the evaporator when a blow fan mounted at the evaporator is driven and when it halts. The two sensed temperatures are compared, so that when the difference of the two temperatures is below a first set value, a defrost operation starts. When the temperature about the evaporator is above a second set value, the defrost operation is completed.
