Abstract
In a refrigerating and air-conditioning system provided with a heat storage tank, variation patterns of load and weather conditions are predicted. On the basis of the predicted values, optimum outputs of a refrigerating machine at individual time points within a predetermined operation period are determined for possible water temperatures of the heat storage tank and stored in a memory. In accordance with the actual water temperature of the heat storage tank, the optimum output of the refrigerating machine is retrieved from the memory and utilized for the operation thereof.
