METHOD FOR CONTROLLING NUMBER OF PUMPS, DEVICE FOR CONTROLLING NUMBER OF PUMPS, PUMP SYSTEM, HEAT SOURCE SYSTEM, AND PROGRAM

摘要

This method for controlling the number of pumps has a step of increasing/decreasing the number of operating pumps on the basis of the flow rate of a heating medium that is pumped to a load (40) by a plurality of pumps connected in parallel or the thermal load required by the load, and a frequency command value sent to the pumps of the plurality of pumps that are operating.
