Abstract

The invention discloses a networking method and device for a multi-connected air-conditioning system, and the air-conditioning system. Wherein, the method includes: the first type of unit receives a trigger signal, wherein the trigger signal is used to start the first type of unit, and the first type of unit provides an interface for the second type of unit to access the communication network; The first type unit determines whether all the second type units joining the communication network are the second type units in the multi-connected air-conditioning system where the first type unit is located; wherein, after the first type unit completes the joining In the case of the confirmation operation of all second-type units of the communication network, the networking is completed. The invention solves the technical problem that the communication reliability between the first type units in the same refrigerant system is not strong.

Description

technical field [0001] The present invention relates to the field of air conditioning, in particular to a networking method and device for a multi-connected air conditioning system, and an air conditioning system. Background technique [0002] A multi-connected air conditioner is usually composed of an outdoor unit and multiple indoor units, which are connected to each other through refrigerant copper pipes to form a refrigerant system. The devices in a refrigerant system work together, so the refrigerant systems need to form a separate network. Wired communication (such as Controller Area Network (CAN) communication) can use dedicated communication lines to physically divide the network, and after using power carrier communication, since the power lines are interconnected, all internal units of the refrigerant system They are all in the same network, so the reliability of the communication between the internal units under the same refrigerant system is not strong. [0003]...
