摘要： PROBLEM TO BE SOLVED: To operate an inverter-driven turbo freezer at high efficiency, and perform an optimum capacity control according to various operation modes in controlling the number of inverter-driven turbo freezers in a heat source system having a plurality of inverter driven turbo freezers. SOLUTION: When the number of inverter-driven turbo freezers 1c-1d is controlled by the controller 9 according to a requested heating value to be born by a plurality of inverter-driven turbo freezers 1c-1e, the controller 9 determines a load ratio range where a result factor becomes a predetermined value or more in the relation between the result factor of the freezers 1c-1e determined depending on the temperature of cooling water detected by a thermometer t and a load ratio, and controls the inverters of the freezers 1c-1e so that the load ratios of the individual freezers 1c, 1d and 1e are within the determined load ratio range.
