A method of controlling the operation of a refrigerator of a type having a capacity control mechanism adapted to control the capacity of the refrigerator in such a manner as to make the temperature of the cold water supplied to an air conditioner coincide with a predetermined set temperature of cold water. The apparatus is adapted to vary the set temperature of the cold water in accordance with the level of the load imposed on the air conditioner, and to determine the difference of the new set temperature of the cold water with the actually measured temperature of the cold water. The apparatus effects the control of the capacity control mechanism of the refrigerator such that the above-mentioned difference of the temperature is nullified. In consequence, the efficiency of the refrigerator during partial-load operation is remarkably improved.

In a refrigerator having a capacity control mechanism adapted to control the capacity of said refrigerator in such a manner that the temperature of cold water supplied to a plurality of individual controllable air conditioners coincides with a predetermined set temperature value, an apparatus for controlling the operation of said refrigerator comprising: a plurality of overload detecting devices, each of which is adapted to detect the loading condition of a respective one of said air conditioners, which in turn constitutes the load on said refrigerator, and to produce an overload signal that is indicative of whether or not the respective one of said air conditioners is overloaded; a cold water temperature computation unit adapted to calculate the set temperature value of the cold water in accordance with the overload signals coming from said overload detecting devices and to produce a signal corresponding to the calculated set temperature value; a cold water temperature detector adapted to detect the temperature of said cold water; and a control means adapted to determine the difference between the measured cold water temperature derived from said cold water temperature detector and said set temperature value of the cold water temperature derived from said cold water temperature computation unit and to control the capacity control mechanism of said refrigerator in accordance with said difference.
