Claim 2:
3. An air conditioner control method comprising:
specifying a plurality of air conditioners to be controlled based on an acquired audio signal;
storing, for a plurality of refrigerant groups, an air conditioner management table in which pieces of identification information on one or more outdoor units and a plurality of indoor units are registered in association with each other, the one or more outdoor units and the plurality of indoor units belonging to the plurality of refrigerant groups;
storing an air conditioner specification table that identifies a plurality of people and correlates one of the plurality of indoor units with each of the respective plurality of people;
acquiring an audio signal for controlling a plurality of air conditioners from a mobile terminal;
identifying a person who is a source of the acquired audio signal;
identifying an indoor unit correlated with the identified person based on the stored air conditioner specification table;
identifying an outdoor unit belonging to an identical refrigerant group to the identified indoor unit based on the air conditioner management table,
specifying the identified indoor unit and outdoor unit as one of the plurality of air conditioners to be controlled
specifying an air conditioner correlated with the identified person as one of the plurality of air conditioners to be controlled based on the stored air conditioner specification table,
specifying, as the plurality of air conditioners to be controlled, the one or more indoor units associated with a selected refrigerant group from the two or more refrigerant groups identified by a selected keyword contained in the acquired audio signal and the single outdoor unit belonging to the selected refrigerant group,
generating control commands for executing, based on the acquired audio signal, control of the plurality of specified air conditioners; and
transmitting, to the plurality of specified air conditioners, the control commands generated by the central processing unit,
wherein the plurality of air conditioners to be controlled are selected from a group of indoor units and outdoor units arranged into the two or more refrigerant groups such that each of the two or more refrigerant groups includes a single outdoor unit selected from the group of indoor units and outdoor units and at least one of the indoor units selected from the group of indoor units and outdoor units,
wherein the two or more refrigerant groups are identified by one or more keywords, respectively, such that each of the two or more refrigerant groups is uniquely identified by one of the one or more keywords,
wherein the air conditioner specification table identifies a plurality of people and uniquely correlates one of the plurality of indoor units with each of the respective plurality of people.
