Abstract: An air conditioning control apparatus acquires an audio signal for controlling air conditioners (outdoor units and indoor units) from a mobile terminal via the Internet. The air conditioning control apparatus specifies from among the air conditioners at least one air conditioner to be controlled based on the acquired audio signal. The air conditioning control apparatus generates control commands for controlling the specified air conditioner based on the acquired audio signal. The air conditioning control apparatus transmits the generated control commands to the specified air conditioner.

Abstract: A remote controller includes a wireless communication unit wirelessly communicating with a wireless device transmitting sensor information serving as an environmental index for an air-conditioning target space for an air-conditioning apparatus and wirelessly communicating with an information terminal transmitting user-set operation information of a user of the air-conditioning apparatus; an air-conditioning control unit transmitting the sensor information and the user-set operation information to a main body of the air-conditioning apparatus; and a mode switching unit switching between a client mode in which the sensor information is acquired from the wireless device and a server mode in which the user-set operation information is received from the information terminal and provides air-conditioning control information corresponding to the user-set operation information to the information terminal.

Abstract: An air-conditioning system includes: a plurality of indoor units including respective wireless communication units each of which emits radio waves; and a mobile terminal unit configured to wirelessly communicate with each of the wireless communication units. The mobile terminal unit detects the radio waves emitted by the wireless communication units, and makes a notification indicating a presence of one or ones of the indoor units that are determined operable based on radio wave intensities of the detected radio waves.

Abstract: A wireless communication system includes a plurality of wireless communication devices each including a display unit, and an information terminal device that performs wireless communication with each of the plurality of wireless communication devices. The information terminal device includes a field intensity calculation unit that determines a field intensity of each of the plurality of wireless communication devices, and a communication device selection unit that selects at least one wireless communication device based on each field intensity determined by the field intensity calculation unit.
