PROBLEM TO BE SOLVED: To provide an air conditioning system capable of compatibly attaining energy saving and comfortability.SOLUTION: The air conditioning system includes an air conditioner 1, a heat source device 2 for adjusting the temperature of heat-exchanging water while using switching signals for switching the temperature of the heat-exchanging water between a low-exergy first set water temperature and a high-exergy second set water temperature, and a control device 5, the air conditioner 1 including a heat exchanger 3 in which the heat-exchanging water flows, and a water control valve 6 for increasing/reducing the amount of the heat-exchanging water flowing in the heat exchanger 3 to adjust a difference between the temperatures of the heat-exchanging water before and after flowing in the heat exchanger 3 and the temperature of air-conditioning air to be supplied, the control device 5 including a switching control part 13 for, when an indoor temperature is a set indoor temperature, outputting the switching signal for the first set water temperature and controlling the difference between the temperatures of the heat-exchanging water to be a set water temperature difference, and for, when the indoor temperature is outside the set indoor temperature, outputting the switching signal for the second set water temperature and controlling the temperature of the air to be supplied to be a set supply air temperature.SELECTED DRAWING: Figure 1 |
