NUMBER-OF-MACHINES CONTROL DEVICE FOR HEAT SOURCE SYSTEM, METHOD THEREFOR, AND HEAT SOURCE SYSTEM

摘要

The purpose of the present invention is to prevent frequent repetition of the starting and stopping of heat source machines. When the current operating status fulfills basic conditions for increasing the number of machines, the present invention determines whether or not basic conditions for reducing the number of machines would be fulfilled if the number of currently operating machines is increased by 1, and, if a determination is made that the basic conditions for reducing the number of machines would not been fulfilled, starts up one heat source machine. When the current operating status fulfills the basic conditions for reducing the number of machines, the present invention determines whether or not the basic conditions for increasing the number of machines would be fulfilled if the number of currently operating machines is reduced by 1, and, if a determination is made that the basic conditions for increasing the number of machines would not been fulfilled, stops one heat source machine.
