  • the amount of cold water supplied from the central heat source device 40 to the outside air cooling coil 11 is adjusted by the opening degree of the valve 14.
  • the amount of cold water that is used by the outside air cooling coil 11 and then supplied to the return air cooling coil 12 is adjusted by the opening degree of the valve 15 and the valve 16. Further, when the amount of cold water used in the return air cooling coil 12 is not sufficient after the use of the outside air cooling coil 11, the cold water is returned from the central heat source device 40 by opening the valve 17. Directly supplied to the cooling coil 12.
  • FIG. 8A shows the flow of cold water when the valve 14 and the valve 15 are opened to the same extent so that all the cold water used in the outside air cooling coil 11 is supplied to the return air cooling coil 12. It shows with.
  • FIG. 8B shows that the valve 14, the valve 15, and the valve 16 are opened, so that a part of the cold water used in the outside air cooling coil 11 is supplied to the return air cooling coil 12 and is unnecessary.
  • the flow of cold water when the cold water is drained without passing through the return air cooling coil 12 is indicated by a bold line.
  • FIG. 8C when the valve 14, the valve 15, and the valve 17 are opened, the cold water used in the outside air cooling coil 11 and the cold water from the central heat source device 40 are supplied to the return air cooling coil 12.
  • the outside air cooling coil 11 is connected in series with the return air cooling coil 12. With such a configuration, the cold water used in the outside air cooling coil 11 can be reused in the return air cooling coil 12. Therefore, it becomes possible to perform the air conditioning control in which energy consumption is further efficiently saved.
  • the refrigerator 41 and the cooling tower 42 of the central heat source device 40 are not in each building, and when performing air-conditioning control by DHC (District Heating and Cooling), cold / hot water may be supplied from the outside. (However, there is a water pump 43 that sends cold and hot water to each air conditioner).
  • the total consumed energy in the air conditioning control system is the total value of the consumed energy of the water pump, the outside air cooling coil, the return air cooling coil, and the blower fan.
  • each measured value measured by each sensor is transmitted from each sensor to the air conditioning linkage control device 50 via the air conditioner 30 .
  • the present invention is not limited to this, and each measurement value may be directly transmitted from each sensor to the air conditioning cooperation control device 50.
  • the PMV value is used as a comfort index for human thermal sensation.
  • air conditioning control may be performed using a standard effective temperature, a new effective temperature, or the like.
  • embodiments may be combined as much as possible. A higher effect can be obtained by combining the implementation states.
