Air-conditioning system

An air-conditioning system comprising:

• a first air-conditioning apparatus management apparatus, including a management communication device, a management processor, and a management memory;
• and
• an first air-conditioning apparatus, including an air-conditioning communication device, an air-conditioning processor, and an air-conditioning memory, configured to transmit and receive various signals via the air-conditioning communication device to and from the first air-conditioning apparatus management apparatus, wherein
• the first air-conditioning apparatus management apparatus manages the first air-conditioning apparatus,
• an operational state of the first air-conditioning apparatus management apparatus is linked to an operational state of the first air-conditioning apparatus,
• a first software set stored in the management memory is updated based on the operational state of the first air-conditioning apparatus management apparatus,
• a plurality of air-conditioning apparatus management apparatuses, comparable to the first air-conditioning apparatus management apparatus, are provided and communicable with each other and with the first air-conditioning apparatus management apparatus, and
• the first air-conditioning apparatus management apparatus updates a second software set in a second air-conditioning apparatus management apparatuses of the plurality of the air-conditioning apparatus management apparatus, based on an operational state of the second air-conditioning apparatus management apparatus, while continuing to manage the first air-conditioning apparatus,
• when a version of the first software set in the first air-conditioning apparatus management apparatus is newer than a version of the second software set in the second air-conditioning apparatus management apparatus and an operational state of the first air-conditioning apparatus management apparatus meets a transmission start condition, the first air-conditioning apparatus management apparatus updates the second software set in the second air-conditioning apparatus management apparatus,
• wherein
• the first air-conditioning apparatus management apparatus transmits the first software set in the first air-conditioning apparatus management apparatus, and restarts the second air-conditioning apparatus management apparatus, to update the second software set in the second air-conditioning apparatus management apparatus, and
• the first air-conditioning apparatus management apparatus transmits the first software set in the first air-conditioning apparatus management apparatus, and restarts the first air-conditioning apparatus to update the first software set in the first air-conditioning apparatus.
