Abstract:
A method for controlling temperature of a refrigerator comprising:defining a plurality of temperature divisions including at least a first temperature division and a second temperature division of ambient temperature, each division including upper and lower temperature values, and determining first on-temp/off-temp values for turning on/off the refrigerator in the first temperature division and second on-temp/off-temp values for turning on/off the refrigerator in the second temperature division; detecting ambient temperature and transferring signals indicative of the ambient temperature to a control processor; enabling the on-temp/off-temp values by the control processor in response to the ambient temperature signals; and determining in response to the ambient temperature signals whether the ambient temperature is within the first temperature division and adjusting the first on-temp/off-temp values to the second on-temp/off-temp values if the ambient temperature changes from the first temperature division to the second temperature division.
