  • the present invention relates to a refrigerator having cooling and freezing compartments at different temperatures.
  • Cooling compartment is utilized preferably for storing fresh food and freezing compartment for storing frozen food.
  • Refrigerators are cooled by operating the compressor by using a heat sensor disposed to the cooling compartment.

  • the control unit obtains the compressor operation ratio from the ratio of the operation time to the cycle time that is the sum of the operation time and stopping time in the previous cycle.
  • the control unit prevents the freezing on and around the evaporator by operating the fan and the heater. If the operation ratio is between the lower limit operation ratio and the upper limit operation ratio, the control unit waits for the compressor to operate at a number equal to a limit value within this interval stored in the memory of the control unit, and to reach the turn-off number, and operates the heater without turning the fan on when the number is reached. If the operation ratio is at the upper limit operation ratio or above, the control unit provides the compressor to reach the compressor cut-in temperature by operating the heater and the fan. Thus, the control unit regulates the operation of the heater and the fan by considering the operation ratios of the compressor. The air heated by the heater is delivered to the evaporator by means of the fan. An effective cooling is provided to be performed in different situations that change according to the cooling device ambient temperature and the door opening frequency.
  • the control unit turns the heater off and maintains the cooling process by operating the compressor again when the sensor detects that the compartment temperature has reached the compressor cut-in temperature after the control unit has operated the heater.

After the compressor stops, the steps in which it is controlled whether or not the operation ratio is lower than the lower limit operation ratio or higher than the upper limit operation ratio are started. If the operation ratio is lower than the lower limit operation ratio or higher than the upper limit operation ratio, the step wherein the heater and the fan are operated is performed. If the operation ratio is between the lower limit operation ratio and the upper limit operation ratio, it is inquired whether or not the compressor operation ratio remains between the lower limit operation ratio and the upper limit operation ratio in all of the cycles, the amount of which is a consecutively predetermined number.
  • the step wherein the heater is operated is started. In all of the steps wherein the heater is operated, it is controlled whether or not the cooling compartment temperature has reached the compressor cut-in temperature. When the cooling compartment temperature reaches the compressor cut-in temperature, the heater is turned off and the compressor is operated again, returning to the first step wherein the stopping of the compressor is controlled.
