PROBLEM TO BE SOLVED: To provide an air conditioning system showing a superior energy saving characteristic in which cold heat and/or hot heat is supplied from a circulating fluid circulated by a pump to a heat source machine of an air conditioner.SOLUTION: An air conditioning system 100 comprises a variable capacity pump 20; a cooling tower 80 and a boiler 90; a plurality of air conditioner devices 30; a plurality of flow rate adjuster valves 35; and a controller 70. The pump circulates the circulating fluid. The cooling tower cools the circulating fluid. The boiler heats the circulating fluid. Each of a plurality of air conditioner devices has a refrigerant circuit including heat source machines 40 for receiving cold heat and hot heat from the circulating fluid. The flow rate adjuster valve is arranged in correspondence with each of the heat source machines to cause an amount of circulating fluid flowing in its corresponding heat source machine to be variable. The controller adjusts a capacity of pump on the basis of the state of the flow rate adjuster valve.SELECTED DRAWING: Figure 1 |
