This control device (100) for refrigerating and air conditioning devices comprises: a demand level determining unit (130) for determining the demand level; a total operating capacity calculating unit (140) that calculates, during each first control cycle, the total operating capacity, which is the total of the operating capacities for each of a plurality of refrigerating and air conditioning devices; a total operating capacity upper limit setting unit (150) that sets, during each second control cycle, an upper limit for the total operating capacity on the basis of the upper and lower limits for the operating capacities of the plurality of refrigerating and air conditioning devices, the total operating capacity, and the demand level; a cooperative controlling unit (160) that determines, during each second control cycle and on the basis of the total operating capacity and the upper limit, a provisional total operating capacity, wherein the total operating capacity is no more than the upper limit; and an optimized number of units controlling unit (170) that determines, during each first control cycle, the number of refrigerating and air conditioning devices in operation and the operating capacity on the basis of the total operating capacity, the provisional total operating capacity, and the relationship between the operating capacity and the coefficient of performance, such that the overall coefficient of performance for the plurality of refrigerating and air conditioning devices is a maximum. |
