Group control system and control method for module type central air-conditioners

Abstract

The invention discloses a group control system for module type central air-conditioners. The group control system comprises n groups of machine set sub-control systems and a plurality of indoor unit controllers. Each group of machine set sub-control system comprises a main machine set controller and m auxiliary machine set controllers and further comprises a centralized control device, wherein the centralized control device is respectively connected with input ends of the main machine set controllers through first buses, and output ends of each group of main machine set controller are in series connection with the auxiliary machine set controllers through second buses. The invention further discloses a control method of the group control system for the module type central air-conditioners. The centralized control devices set switches and operating parameters of the main machine set controllers and transmit control instructions to a main controller, the main controller receives the control instructions and sets switches of the auxiliary machine set controllers according to air-conditioner load parameters so as to control running of an air-conditioner machine set, the auxiliary machine set controllers feed self running state parameters back to the main machine set controller, and the main machine set controller feeds self running state parameters and the running state parameters of the auxiliary machine set controllers back to the centralized control devices to perform display.

Description

technical field

[0001] The invention relates to a group control system and a control method of a modular central air conditioner. Background technique

[0002] The current modular central air-conditioning outdoor units and indoor units (terminals) are installed separately in groups, and the indoor units and outdoor units are controlled separately. When there are many installed units and indoor units (terminals), the installation Relatively scattered and inconvenient to manage. Contents of the invention

[0003] The invention provides a modular central air-conditioning group control method, which can not only manage the sub-control systems of each group of units and indoor units in a unified manner, which is convenient for maintenance and management, but also can remotely control and monitor the central air-conditioning units and indoor units and process them .

[0004] The present invention adopts the following technical solutions: a group control system of a modular cen...
