Research on indoor environment for the terminal 1 of Chengdu Shuangliu international airport

In this paper, indoor thermal environment of the Terminal 1 of Chengdu Shuangliu International Airport (CSIA) is taken as study object, by means of investigating, measuring and simulating based on computational fluid dynamics (CFD) codes. A total of 569 participants provided 569 sets of physical data and subjective questionnaires, and an indoor thermal comfort meter was used to collect the measured parameters of the indoor environment and the predicted mean vote (PMV). The accepted thermal comfort environment range is obtained. Results considering personal mobility obtained from measuring a number of points have been compared and analyzed, which provides some drawbacks for airflow distributions. Main characteristics of vertical temperature distributions in winter and summer conditions are discussed, measured by the equipment named scaling ladder. The comparison held measuring and CFD results generally shows a good agreement, which confirms that the veracity of the CFD simulation can be achieved. The results are of great importance for designing indoor thermal environment and air conditioning systems of the Terminal 2 of CSIA.
