冷水集中空调系统的虚拟调试研究及验证分析OA

A hybrid data-driven and physics-driven approach is adopted to establish a dynamic simulation model for a central chilled water air conditioning system.And industrial-grade controllers are utilized to construct a signal conversion equipment.Virtual commissioning technology is studied through hardware-in-the-loop collaborative simulation between the dynamic model and the controller.With the central chilled water air conditioning system of a commercial office building employed as a test case,the feasibility of virtual commissioning is validated.The results indicate that dynamic processes can be effectively captured by the hybrid simulation model,and simulation deviations maintained within 2℃.Robust data interaction is achieved between the virtual commissioning platform and the simulation model,keeping supply-return temperature differences of chilled water and cooling water within 5℃.Furthermore,the platform's capability is demonstrated in verifying the control system's response process under equipment failure conditions.
