Abstract

A refrigerator control method of the present embodiment comprises the steps of: operating a compressor by operating a first cooling cycle for cooling a first storage chamber, and operating a first cold air supply means for the first storage chamber; and operating the compressor by switching into a second cooling cycle for cooling a second storage chamber, and operating a second cold air supply means, when a stop condition of the first cooling cycle is satisfied, wherein the cooling capacity of the compressor in the current second cooling cycle is determined on the basis of the representative temperature of the second storage chamber during one operating cycle which includes the previous first cooling cycle and the previous second cooling cycle, and a control unit performs control such that the compressor is operated in the current second cooling cycle with the determined cooling capacity.

First claim

What is claimed is:

1. A method for controlling a refrigerator, comprising:
operating a current first cooling cycle to cool a first storage compartment;
switching to a current second cooling cycle to cool a second storage compartment when a stop condition of the first cooling cycle is satisfied; and
determining an operation time of the current second cooling cycle based on a representative temperature of the second storage compartment during a previous operating cycle, which includes a previous first cooling cycle and a previous second cooling cycle.

2. The method of claim 1 , wherein the operation time is determined to be equal to a previous operation time of a previous second cooling cycle when the representative temperature is within a temperature satisfaction range of the second storage compartment.

3. The method of claim 2 , wherein the operation time is determined to be different from the previous operation time when the representative temperature is outside of the temperature satisfaction range.

4. The method of claim 3 , wherein the operation time is determined to be greater than the previous operation time when the representative temperature is higher than an upper limit temperature of the temperature satisfaction range.

5. The method of claim 3 , wherein the operation time is determined to be less than the previous operation time when the representative temperature is lower than a lower limit temperature of the temperature satisfaction range.
