ABSTRACT:
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.
