Practice of swarm intelligent control system in a high-efficiency chiller plant

The swarm intelligent control system is a new type of building automation control system, which is different from the traditional building automatic control system. It divides the building electromechanical equipment system into several basic units, each unit is configured with a computing processing node（CPN）, CPNs between the basic units in accordance with the spatial location relationship are connected into a centerless and flat network system. Combined with the engineering practice of a commercial project, the design principles and annual operation effects of the swarm intelligent control system of the refrigeration station are analysed. The system is put into use before the opening of the mall, realizing the automatic and efficient operation of the refrigeration station under unattended. From June to October 2019, the average energy efficiency of the refrigeration station reaches 4.50, compared with the energy efficiency limit of 3.31 for national standard refrigeration stations, the energy saving rate reaches 26.44%. The swarm intelligent control system can be applied to different forms of chiller plants, through standardized design, construction commissioning and general control strategy software download, quickly “copy” the experience of efficient chiller plants, to solve the problems of low degree of automation, low operating efficiency and high energy consumption level of air conditioning refrigeration stations in public buildings in China.
