Air conditioning-related equipment includes: a first connection portion to which wiring for transmitting high voltage along with communication is connected; a second connection portion to which wiring dedicated to communication and not to power transmission or wiring for transmitting low voltage along with communication is connected; and a connection circuit that connects the first connection portion and the second connection portion, wherein the connection circuit includes an isolation circuit that blocks power transmission and transmits a signal pertaining to communication.

Air conditioning-related equipment and air conditioning system

A node performs multi-hop communication. The node includes a relay node determiner that determines a relay node from a plurality of relay node candidates having path information of a path to a master node. The relay node performs relaying. At least when communication frequencies of the relay node candidates are within a predetermined range, the relay node determiner determines the relay node so that a relay node candidate with a higher communication frequency is more likely to be determined as the relay node than a relay node candidate with a lower communication frequency.
