Abstract
A cold-accumulation type refrigerator having variable length cycle for cooling by means of the cold-accumulation material. The cycle length is a function of refrigerator load. The refrigerator includes a refrigerating cycle to cool a refrigerator compartment and the cold-accumulation material, a load detecting device, such as a room temperature detecting device, to measure an amount of a load to be cooled, clock counting device to generate a time data, and a control device, such as microcomputer. The control device controls the operation of the refrigerator which operates in a first mode (ordinary cooling operation), a second mode wherein the refrigerator compartments are cooled by means of the cold accumulation material and a third mode wherein the cold accumulation material is cooled. The control device controls the time period for second and third mode operation as a function of load to be cooled.
