Abstract

The invention discloses a cold station group control system and a control method thereof. The method includes the steps that a device controller is used for synchronizing table entry data updated in a local virtual point location table to a remote virtual point location table in a server for feedback, wherein table entries in the remote virtual point location table are the same with table entries in the local virtual point location table; and the device controller receives the table entry data, issued by the server, in the remote virtual point location table and synchronizes the table entry data into the corresponding table entries in the local virtual point location table. By means of the technical scheme, the complex processes of manual debugging and docking are omitted, fast docking of the table entry data in the remote virtual point location table and the table entry data in the local virtual point location table is achieved, the control process of an existing cold station group control system is optimized, labor and the time cost are greatly saved, and the configuring and controlling efficiency is improved.

Description

technical field [0001] Embodiments of the present invention relate to electrical control technology, and in particular to a cold station group control system and a control method thereof. Background technique [0002] With the continuous improvement of people's service quality requirements, the proportion of HVAC energy consumption in the total building energy consumption is increasing, and the energy consumption of cooling stations is the main part of HVAC energy consumption. Therefore, the cooling station system Skill optimization is particularly important for the total energy consumption of buildings. [0003] The current cold station system is mostly a cold station group, which includes multiple types and a large number of refrigeration equipment at the same time, typically including refrigerators, cooling towers, cooling water pumps, chilled water pumps, and manifolds. These equipment may include multiple , and distributed in different locations, connected to each othe...
