Cooling tower system based on centerless network, cooling tower controller and control method

Abstract

The invention provides a cooling tower system based on a centerless network, a cooling tower controller and a control method of the cooling tower system. The method includes the steps that one cooling tower controller is arranged on each cooling tower, and all the cooling tower controllers are connected to form the centerless network; when it is judged that a certain trigger condition is met, the cooling tower controllers initiate adjusting tasks; the cooling tower controllers start to interact with the adjacent cooling tower controllers; and after interaction is conducted multiple times, the whole system confirms optimized operation parameters of all the cooling towers, and the corresponding cooling towers are controlled to be in the corresponding operation states according to the optimized operation parameters. The method is based on the centerless network, all the cooling towers connected in parallel finish target control equally and autonomously in a coordinated manner, the optimization control scheme is worked out in a distributed manner, the workload generated during manual configuration and debugging of a traditional control manner is lowered, and the control equipment is plugged and used immediately; and the control efficiency, robustness and expandability of the system are improved.

Description

technical field [0001] The invention relates to the technical field of building energy saving and intelligent control, in particular to a cooling tower system based on a decentralized network, a cooling tower controller and a control method. Background technique [0002] In the cooling water system of the central air conditioner, multiple cooling towers are usually used in parallel to cool the high-temperature cooling water flowing out from the condenser side of the cooler. The cooling tower system has two control subsystems, the cooling water circuit and the cooling tower fan. The control of the cooling water temperature is achieved by adjusting the number of cooling towers that are turned on and the operating frequency of their fans. [0003] In the existing cooling tower control system, centralized control is usually adopted, that is, one cooling tower controller is set up for multiple cooling towers in the cooling station. The current common control strategy is that the ...

Problems solved by technology

[0004] The disadvantage of this control method is that in actual construction, a lot of on-site secondary development, configuration and debugging, wiring and other work are required; when the equipment changes, the central controller needs to be reconfigured and debugged; To optimize the control, it is necessary to model the specific equipment. Professional personnel will write the model into the central controller and further debug the controller. The labor cost and time cost are very high.
