“…The variation of AHUs’ cooling capacities mainly had resulted from the occupancy rates in an airport terminal, as was analysed in the previous research. 37 An airport terminal is not always fully occupied as it is in the design condition. Therefore, the uneven occupant distribution both in time and space would cause dramatic variation in the actual demand for cooling load.…”

Airport terminals are key infrastructures with rapid development currently, where the air-conditioning (AC) systems aim to guarantee the normal operation. This research investigated the AC systems in seven Chinese hub airport terminals by a large-scale on-site measurement. The average annual electricity consumption was 177 kWh/(m2 · year), in which 30–60% was consumed by AC systems. The terminal device of AC systems is one of the key components restricting the cooling performance. The commonly used terminal devices (i.e. air handling units) accounted for 40–74% of the AC electricity consumption. As an alternative, the AC system combining radiant floor and displacement ventilation could save 34% of the AC electricity consumption in one investigated airport terminal. Furthermore, the designed cooling capacities were 132–176 W/m2, while the measured values were only 43–90 W/m2. Thus, the AC systems, especially the terminal devices, should have the ability to adjust cooling capacity over a wide range to cope with this prevailing situation of low load rates. This study is beneficial for the design and operation of AC systems in airport terminals.

“…Their result showed that the passenger density exceeded the design value in only 3.6% of total duration. The maximum usage ratio of departure floor was only 54.8-64.4%, and the maximum actual demand of cooling load for primary air (25 W/m 2 ) was obviously lower than the design value (47 W/m 2 ), which means the energy consumption of the HVAC systems in airports can be significantly reduced if the amount of mechanical outdoor air can be adjusted with variation of actual occupancy rates [25]. Furthermore, Liu et al, investigated the passenger flow in main public areas of a Chinese hub airport terminal in typical three months of three different seasons.…”

“…Zhu et al [27] proposed a simulation-based quantitative analysis and an evaluation method to solve the comparison problem of water-water transhipment coal terminals. Liu et al [28] used the simulation method to analyze connection of indoor occupants with the energy consumption of heating, ventilation, and air-conditioning (HVAC) in airport terminals which are characterized by passenger flow. Archetti et al [29] presented the results of a simulation study aimed at assessing an on-demand transportation system.…”

Because of China’s vast territory, large population, and huge demand for bulk materials, the railway transportation mode has always received considerable attention. For long-haul transportation, railway transportation can provide a scheduled-based transport plan, all-weather transport service, and cheaper carry instead of other transport modes. The study described in this paper attempts to develop a simulation platform for optimizing the placing-in and taking-out wagons system on the branch-shaped freight operation network (PTWS-BSFON). The operation process of PTWS is thoroughly analyzed from three aspects of decoupling-coupling wagons subsystem, placing-in local wagons subsystem, and taking-out local wagons subsystem. And then the simulation platform encompassing two typically shunting modes of PTWS are developed by Arena software. Under scenarios of PTWS-SO and PTWS-SSMS, the hierarchical structure of the shunting strategies is, respectively, outlined in the simulation platform. Finally, the shunting strategies based on the simulation platform are carried out by concrete examples, which prove the rationality of the methodology in applying different strategies and enhancing the performances of the PTWS-BSFON.
