Study on indoor thermal environment based on CFD simulation

The definitions of the evaluation index and heat comfort of the indoor thermal environment were simply described first. Then the tested room was taken as the model room and corresponding mathematical models. A-part of the tested parameters were taken as the border conditions and the k-epsilon equation models of CFD procedures, were used to simulate the indoor environment parameters distribution of student dormitory room in Chongqing University. Through comparing and analyzing the tested results, it is shown that the experimental results of temperature field are identical to the analysis results and the mathematical model used in the simulated process of the indoor heat environment is reasonable. Finally, the simulation results of the temperature field and speed field in the room were analyzed. At the same time, the calculated simulation data at different time were analyzed, and then the causes for the indoor thermal environmental change were pointed out and the evaluation of the indoor thermal comfort was gotten.
