Abstract:
An air conditioning system according to the present invention has: an outdoor unit that includes a compressor; a plurality of indoor units that are connected to the outdoor unit by means of refrigerant pipes; a control device that controls the outdoor unit and the plurality of indoor units; and a server device that can communicate with the control device. The server device has: a first prediction unit that predicts room temperatures in air-conditioned spaces where the plurality of indoor units are installed, by using a plurality of operating state quantities related to an air-conditioning operation; and a second prediction unit that uses the room temperatures predicted by the first prediction unit and a set temperature serving as a target value of the air-conditioning operation to predict the points in time when each of the plurality of indoor units reaches reach a thermo-on state and a thermo-off state. The control device has a control unit that controls driving of the compressor in accordance with the points of time when the individual indoor units are set in the thermo-on state or the thermo-off state, by using the prediction results of the second prediction unit. The present invention provides an air conditioning system and the like capable of ensuring user comfort while suppressing power consumption related to air-conditioning operations by reducing the number of stops and restarts of the compressor.
