Abstract

The invention provides a control method and system for a central air-conditioning module. The central air-conditioning module comprises a plurality of central air conditioners, and each central air conditioner comprises a main controller and a first wireless communication module connected with the main controller. The control system comprises a second wireless communication module, and the second wireless communication module is connected with the first wireless communication modules in a wireless manner. The second wireless communication module transmits a control command to the main controllers through the first wireless communication modules to control the operating parameters of the central air conditioners, and therefore wireless control over the central air conditioners can be achieved through the second wireless communication module and the first wireless communication modules; and the problems that in the prior art, due to aging of a central-air-conditioner bus, communication faults of the central air conditioners are caused, and normal work of the central air conditioners is influenced are solved.
