Definitions

  • This invention is related to a control method developed to eUminate the problem of cooling failure at low ambient temperature in refrigerators, preferably dual- compartment refrigerators.
  • compressor is activated by a thermostat located in the refrigerating compartment. Since the thermostat is affected by outside temperature, when the outside temperature is low, the compressor is not activated properly and as a result sufficient cooling is not provided. According to the known techniques, to eliminate the problem of cooling failure at low outside temperature, temperature of the refrigerating compartment is increased in a short period of time so that the thermostat can activate the compressor.
  • the objective of this invention is to provide a simple and low-cost control method which will enable refrigerators to perform cooling at low ambient temperatures.
  • Figure 1 is a schematic view of a refrigerator.
  • Figure 2 - is a flow diagram of a cooling control method in which temperatures of the freezing compartment and the refrigerating compartment are controlled independently.
