Heat source machine complex system and operation method of heat source machine complex system

摘要

PROBLEM TO BE SOLVED: To provide a heat source machine composite system for performing a highly efficient operation and a method for operating the same.SOLUTION: A heat source machine composite system 1 is provided with: an electric heat source machine 11; an absorption heat source machine 21; a heat source machine power consumption acquisition device 53 which acquires power consumption of both heat source machines 11, 21; a monitoring device 31 which measures a power demand BD of the whole building in which both heat source machines 11, 21 process heat loads; and a control part 55. A first demand management value is set by adding absorption priority power consumption to the maximum value of power consumption of the building except the power consumption of both heat source machines 11, 21. The control part 55 controls operations of the electric heat source machine 11 and the absorption heat source machine 21 to utilize capability of the absorption heat source machine 21 to the utmost when the power consumption of the whole building is equal to or more than a first switching value set based on the first demand management value in a state of leaving reserve power in the capability of the absorption heat source machine 21 in the case that at least one of the electric heat source machine 11 and the absorption heat source machine 21 operates to process the heat loads of the building.SELECTED DRAWING: Figure 1
