Thermal dynamic response characteristics of pipe network for variable flow air conditioning water systems

In the pipe network of the variable flow air conditioning water system with complicated topology, the transition of the medium flow and temperature has obvious time delay characteristics, which renders the pure delay time significantly referable for the optimizing control of the pipe network. In this paper, the thermal dynamic response characteristics of the pipe network are studied from the view of modeling analysis and simulation, and the relationship between the constitutive parameters and thermal dynamic response characteristics is deeply analysed. The simulation model is verified by experiments, and the results show that the model has high accuracy, and can be used for simulating the thermal dynamic response characteristics of the pipe network of variable flow air conditioning water systems, which can provide theoretical support for the subsequent studies on control period optimization and decoupling control.
