PROBLEM TO BE SOLVED: To provide a centralized control system for a freezing-refrigeration facility capable of retaining a temperature in each showcase within a certain range without stopping supply of a refrigerant with respect to an evaporator of each showcase. SOLUTION: In the centralized control system for a freezing-refrigeration facility, a refrigerant intake pressure of a compressor 7 of a refrigerator 3 is set on the basis of information indicating respective cooling states of a plurality of the showcases 1 in a refrigerating cycle supplying the refrigerant from the common refrigerator 3 with respect to evaporators 15 respectively built-in the plurality of showcases 1. Each showcase 1 is equipped with an internal temperature measuring means 29 for measuring an internal temperature of an interior, and the refrigerator 3 is equipped with a compressor control means 33 for controlling the compressor 7 by setting the refrigerant intake pressure of the compressor 7 on the basis of deviation information of the internal temperature and a set temperature set beforehand in each showcase 1.
