<P>PROBLEM TO BE SOLVED: To provide a heat source system can improving the efficiency of refrigerators arranged in series are not operated at peak load, and a control method of the same. <P>SOLUTION: The heat source system 100 includes a cooling water system in which cooling water cooled by a cooling tower 1 circulates, a cool water system in which cool water cooling a load side 3 circulates, a high temperature side refrigerator 2a and a low temperature side refrigerator 2b which are arranged in series in the cool water system that cools cool water, and a control device 71 which is configured to control a cooling fan 6 of the cooling tower 1, a high temperature side cooling water pump 4a, a low temperature side cooling water pump 4b, and a cool water pump 5 as objects to be controlled, wherein cool water is supplied to the load side 3 through a heat storage tank 8 storing the cool water. The control device 71 sets target control values of the objects to be controlled such that an evaluation function indicating energy consumption is minimized in response to a change in at least one of an external air condition, a heat storage amount of the heat storage tank 8, and a required load of the load side 3. <P>COPYRIGHT: (C)2013,JPO&INPIT |
