Embodiment 1

[0018] A method for grouping control of main and auxiliary units in a multi-connected air-conditioning system, the method includes setting the mode of auxiliary units: including:

[0019] Among the machines with consecutive addresses in the system, select any one or several machines except the first address as the auxiliary machine, and the auxiliary machine with the latter address is connected to the auxiliary machine with the previous address, and the previous address is not the auxiliary machine. The machine is the host. When only one group is set in a system, the machine whose address is the first is the master; when multiple groups are set in a system, if there are 1-10 internal machines in the system, set 2, 3, 6, 7, 9 If it is the auxiliary machine, then No. 1 is the main machine, and No. 2 and 3 are in a group with it; No. 4 is the main machine, and there is no auxiliary machine after that, and it is a group by itself; No. 5 is the main machine, and No. 6 and 7 are...

Embodiment 2

[0022] A method for grouping control of master and slave units in a multi-connected air-conditioning system. The method uses the method of setting a master address (master ID): including: setting at least one master address in the system, and the machine corresponding to the master address is the master, The rest of the unconfigured machines are sub-machines, connect the sub-machines to the main address they want to follow, and the sub-machines follow the operating status set by the corresponding main machine on the main address it is connected to. In this way, the main internal unit, external unit, monitoring, etc. do not need any additional operations, and all auxiliary units can operate normally without connecting wire controllers after installation.

[0023] In addition, any indoor unit in the system can be dialed to be set as a secondary machine (maximum support for 63 secondary machines, at least one main machine must be left), and the main address to be followed can ...

Abstract

The invention relates to a group control method for main and auxiliary machines in a multi-split air-conditioning system. The method comprises the following steps: setting any one or more machines except the machine with the first address in machines with continuous addresses in a system as auxiliary machines by adopting an auxiliary machine setting way, and connecting the auxiliary machine with the last address to the auxiliary machine with a previous address, wherein a machine which is not an auxiliary machine on a previous address is a main machine, and a machine with a next address follows the set running state of the machine with the previous address; or setting at least one main address in the system by adopting a main address setting way, and connecting the auxiliary machines to the main address to be followed, wherein a machine which corresponds to the main address is a main machine, other non-set machines are auxiliary machines, and the auxiliary machines follow the set running state of the main machine on the connected main address. By adopting the group control method, the difficulty of installation, debugging and maintenance on construction sites is lowered, and a simple centralized control function can be realized easily without making changes on the communication architecture of the system.

Description

technical field [0001] The invention relates to a method for grouping control of main and auxiliary units in a multi-connected air-conditioning system. Background technique [0002] Multi-connected air-conditioning systems generally include one or several outdoor units connected to several indoor units of the same or different types and capacities to form a circulation system, which can directly provide treated air to one or several areas. Due to the large number of machines, it is inconvenient to operate and control. The existing multi-connected air-conditioning systems generally do not support group control, or require a centralized controller to achieve group control, but the wire controller does not support group control. Therefore, there is still a gap in the system. Contents of the invention [0003] The purpose of the present invention is to provide a method for grouping control of main and auxiliary units in a multi-connected air-conditioning system. [0004] In ...
