Multi-split air conditioning system and control method thereof

Abstract

The invention discloses a multi-split air conditioning system and a control method thereof. The multi-split air conditioning system comprises a plurality of wireless modules and more than one multi-split air conditioner units separately arranged corresponding to all wireless modules, wherein the wireless modules are used for treating received commands; each multi-split air conditioner unit comprises a plurality of air conditioner units and corresponding CAN buses carrying out communication between the wireless modules and the air conditioner units; and the air conditioner units of the multi-split air conditioner units corresponding to the different wireless modules are incorporated into the same group number of the CAN buses so as to utilize the commands treated by the wireless modules tocontrol the plurality of air conditioner units through the CAN buses. By utilizing the properties of the group numbers in a CAN protocol and carrying out networking on a plurality of multi-split air conditioning systems, the air conditioners under different wireless modules actually can still be controlled by setting the same group numbers, so that the operation of users is simplified.

Description

technical field [0001] The invention relates to the field of air-conditioning control, in particular to a multi-connected air-conditioning system and a control method thereof. Background technique [0002] At present, with the general promotion of multi-connected air-conditioning systems, the management and control system of multi-connected air-conditioning systems has emerged as the times require. According to the existing multi-connected air-conditioning system control scheme mainly includes the following methods: [0003] For example, Chinese Invention Patent Announcement CN103615789B discloses a centralized air-conditioning control method based on indoor unit grouping and a multi-connected air-conditioning system. In this solution, centralized control is performed point-to-point through a wireless module through networking. [0004] Another example, Chinese invention patent application publication CN104329774A discloses a method for grouping control of main and auxilia...

AI Technical Summary

Problems solved by technology

[0005] However, in the general commercial multi-connected air-conditioning system, the number of air conditioners is large and involves a large number of internal units (for example, thousands of units), there are still the following problems: In the point-to-point control mode, the control command data packets sent are too Many, put pressure on the entire multi-line control network and wireless modules

In the case of the same wireless module, if the user needs to add an air conditioner to the multi-connected network or remove an air conditioner from the multi-connected network, it may need to re-network, and a multi-connected air-conditioning system has a limit on the number of air conditioners
