Abstract
The invention relates to a method for controlling temperature of a refrigerator. The method includes the steps of judging supercooling, namely judging whether time for continuing a state of temperature detected by a third temperature sensor smaller than a first threshold value reaches a second threshold value or not in refrigerating period of a refrigerating chamber; protecting supercooling, namely increasing set temperature of the refrigerating chamber when the set temperature reaches the second threshold value; stopping refrigerating of the refrigerating chamber when temperature detected by a second temperature sensor is smaller than the set temperature of the refrigerating chamber; stopping supercooling protection, namely stopping supercooling protection after regulated time and restoring the set temperature; and restarting the refrigerating chamber, namely, switching a three-way valve to an evaporator side of the refrigerating chamber, and refrigerating the refrigerating chamber. Therefore, the method for controlling temperature of the refrigerator can reliably prevent a third chamber from supercooling.
