Simulation and analysis of multi-physical field coupling of thermal environment in Olympic Winter Games container rooms

 In order to study the indoor thermal environment of the container room during the Olympic Winter Games, this paper couples the multi-physical field solution for the container rooms and the indoor and outdoor environment, establishes the heat network model of the outdoor environment, the envelope and the indoor environment with coupling the three heat transfer modes of heat conductivity, convection and radiation. The accuracy of the simulation method is verified by comparing and analysing the simulation results with the experimental data. Then, this paper studies the indoor thermal environment of the container rooms with different thermal performance envelopes during the Olympic Winter Games events. The simulation calculates the indoor temperature of 6 different kinds of insulation materials and different thicknesses of rock wool. The results show that the choice of rock wool is more appropriate while combining economy and thermal insulation material characteristics. And when its thickness is 150 mm, the indoor temperature is about 19.6 ℃, meeting the requirements of indoor temperature in winter.
