Control device, heat source system, control method, and control program

The purpose of the present invention is to provide a control device, a heat source system, a control method, and a control program capable of more efficiently conveying a heat medium having a required temperature. This control device is applied to a heat source system (1) provided with a plurality of heat source machines (2a, 2b) connected in series, and is provided with a setting unit. The setting unit sets the outlet setting temperature of the cold water in each heat source machine (2a), (2b) on the basis of the measured value of the cold water flow rate, the measured value of the inlet temperature of the cold water in each heat source machine (2a), (2b), and the required outlet temperature of the cold water in the heat source system (1). 本发明的目的在于提供一种能够更有效地输送所要求温度的载热体的控制装置及热源系统、控制方法以及控制程序。一种控制装置，其适用于具备串联连接的多个热源机(2a)、(2b)的热源系统(1)，所述控制装置具备设定部，所述设定部根据冷水流量的测量值、各热源机(2a)、(2b)中的冷水的入口温度的测量值及热源系统(1)中的冷水的要求出口温度来设定各热源机(2a)、(2b)中的冷水的出口设定温度。
