Abstract

The invention provides an air-conditioning system. The air-conditioning system comprises indoor units, outdoor units and an Ethernet switch, wherein the indoor units and the outdoor units are connected to the Ethernet switch, so that a local area network is formed; and the Ethernet switch is used for communication between the indoor units and the outdoor units in the local area network. By adoption of the technical scheme, the communication speed, the expansion flexibility and the communication performance of the air-conditioning system can be improved, and the network topology is simplified.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular, to an air conditioning system. Background technique [0002] Indoor units and outdoor units generally communicate through the bus, especially in multi-connected air-conditioning systems, there may be as many as 32 outdoor units and as many as 64 indoor units. Communication, internal machine centralized control communication, etc. often require multiple 485 buses. Such as figure 1 As shown, the air conditioning system 100' includes: an indoor unit 102', an outdoor unit 104' and a control device 106'. The communication bus between multiple outdoor units 104' is a thin solid line, the communication bus between the outdoor unit 104' and the indoor unit 102' is a thick dotted line with low density, and the connection between the control device 106' and the indoor unit 102' The bus for inter-communication is a thick solid line, and the bus for communication between th...
