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 plurality of values measured are relatively compared to determine an optical axis deviation direction in which an optical axis of a measurement beam S deviates from a laser beam L. In performing laser welding in the optical axis deviation direction, an irradiation position of the measurement beam S is changed so that the irradiation position of the measurement beam S is moved to a rear side of the center of the optical axis of the laser beam L in the welding direction.
