PROBLEM TO BE SOLVED: To provide a carrying power reduction system in air conditioning facility in which power saving can be accelerated by reducing power consumption. SOLUTION: A plurality of air conditioners AH installed in a building are provided, respectively, with a plurality of variable pumps P1-Pk being driven through motors M in pipelines 4 for introducing heating medium, e.g. hot water or cold water, individually from a heat source machine 3 to each air conditioner AH. Each variable pump P1-Pk is provided with an inverter I for controlling the rotational speed of the motor M in response to a flow rate command. A control means 8 delivers a flow rate command to each inverter I depending on the air conditioning load of each air conditioner AH in order to control the flow rate of heating medium being supplied from each pump to each air conditioner AH thus suppressing useless power consumption of each motor M.
