摘要： A method for controlling temperature in a chamber of a food storage apparatus comprises: (a) inputting a lower and an upper temperature limits T1 and T2, a predetermined elapsed time t1 of the chamber storing a normal amount of food needed for the temperature of the chamber to reach T1 after an initial activating of a cooling device, a predetermined temperature restoring time t3 for the temperature of the chamber to reach T2 from an initial deactivating of the chamber, a plurality of compensating values, and a plurality of reference values; (b) setting a variable A to T1; (c) activating the cooling device; (d) measuring an elapsed time t1' for the temperature of the chamber to reach T1 after an initial activating of the cooling device; (e) comparing the elapsed time t1' with t1' (f) setting the variable A to T1' if t1' is longer than t1; (g) deactivating the cooling device at an instant when the temperature of the chamber reaches the variable A; (h) activating the cooling device again at an instant when the temperature of the chamber is increased by .DELTA.T; (i) measuring a temperature restoring time t3' from the deactivating time to the subsequent activating time of the cooling device and comparing it with t3; (j) comparing a difference .DELTA.t3 between t3' and t3 with the reference values, and setting the variable A to one of the compensating values if t3' is less than t3, otherwise setting the variable A to T1.
