Coupling simulation and experimental research of building and air conditioning chilled water system based on automatic control<br>In this paper, the time step is set to be a shorter time step (5min) closer to the actual system control process. Based on the building thermal characteristic coefficient and room base room temperature simulated by DeST, the room temperature calculation model established by state space method is used to solve the continuous simulation problem of thermal coupling between building room and air-conditioning terminal equipment.<br>At the same time, a detailed water network model is built to realize the joint simulation of building and air conditioning chilled water system. Under the condition of frequency conversion control of chilled water pump and on-off control of air conditioning terminal, the control and regulation process of air conditioning cooling is simulated, and the data of room temperature, cooling capacity of air conditioning, water flow of branch, power consumption of chilled water pump, etc. are obtained. Furthermore, the model is verified by experiment. Comparing the simulation results of the program with the actual measurement results, it can be seen that the simulation program of short time step automatic control building and air conditioning water system coupling calculation transmission and distribution energy consumption established in this paper is reliable and can accurately reflect the control and regulation process of the actual system and the operation energy consumption of chilled water transmission and distribution system.<br>Key words: building; air conditioning chilled water system; coupling; short time step; automatic control; transmission and distribution energy consumption<br>
