Therefore, the energy consumption and cost of these transportation buildings are considerable. In additon, a majority of these special buildings are high and large, so the ventilation rates and passengers thermal comfort should be taken into account. The Eleventh Five-year Plan of China will build 548 new railway stations, some of which are hundred years immortal ones.A study is conducted into the ventilation effectiveness of a ventilation system and indoor human thermal comfort within public transportation buildings (PTB) in China.Fig. Indoor environment in railway station building研究课题在国内外研究情况及水平THE CURRENT RESEARCH CONDITION AND LEVEL OF THE RESEARCH PROJECT AT HOME AND ABROAD:1. There are hardly relative research projects which involves indoor environment quality of these special buidling in China, especially thermal comfort, and only a little report as to some investigations and field surveys in Japan. The most important reason is that China is a great populous nation. 2. Although low energy (cooling) concepts are high developed and have been realized successfully in many projects in all European climate zones, its research are still at the starting stage in China. There are no normative design guideline for comfortable low-energy building and no consistent evaluation criteria for the indoor environment in different climate zones.3. Natural ventilaiton and mechanical ventilation at present havent been applied to large railway station. For example, New Beijing Southern Railway Station, which ran before Beijing Olympic Games, was oppugned for many energy-saving technologies of high cost.国内科研准备工作THE PREPARATION WORK OF THE PROJECT IN CHINA:1. Developed a thermal comfort upper limit from spring to autumn by investigation, field survey in specific indoor environment with natural ventilation, mechanical ventilation and even full air-conditioned. 2. Study numerical simulation tubulence models which involves the solution to the Reynolds Averages Navier-Stokes equations, direct numerical simulation (DNS) and large eddy simulation (LES).Compared the performance of these types of models.国外研究课题的目的及预期目标THE AIM AND EXPECTATION OF THE RESEARCH ABROAD:1. Study Ventilation Rate .As the ventilaiton demard for indoor environment, there is the serious problem that the IEQ in railway station building is generally found to be poor. This mainly caused by inadequate ventilation rates, poor air quality and subjective perception of railway station building. The investigation methods of effect of IAQ and ventilation rates on passengers performance and health using psychological tests are helpful to my research.2. CFD for application to built environment. (For example: Optimising ventilaiton in passive and low-energy bilding using CFD)CFD simulaton is used to provide aditional information on the indoor air quality and comfort conditions for building environment, such as ventilation effectiveness, air exchange effectiveness, effect of flow rate, effect of radiation, effect of supply temperature, etc. In order to minimize potential shortcoming in the design of the ventilation system, indoor airflow simulation was carried out. By simulating different variables it is possible to fine-tune the ventilation concept and thereby achieve balanced comfort conditons. Since the design has been optimized at the design stage, it was not necessary to carry out expensive modifications after completion of the project.3. Study ventilation technology.Study ventilatin technologies and new ventilaiton equips according to passengers performance investigations and tests.研究具体实施方法THE EXPERIMENTAL METHODS AND DATA ANALYSIS METHODS (where required):1. Investigation and field survey for indoor environment.Using field measurement results can propose a series of improvements to improve the overall air quality and in door thermal environment.2. Human test under non-uniform and transient conditionsBased on evaluation of human thermal sensation and indoor air quality under diferent ventilaiton rates and radiation temperatures, human test can gain adaquate experiment datas for application of spcecial environment parameter chosed in transportation building. 3. Computer simulation with experimental validation.Computer simulation has become an increasingly popular tool to predict the energy and environmental performance of buildings, compared to experimental analysis and field survey. 拟留学院校在此学科领域的水平和优势THE LEVEL AND ADVANTAGE OF THE HOSTING FOREIGN INSTITUTION ON THIS PROJECT:Tohoku University founded in 1907 as the third Imperial University of Japan, following the Tokyo Imperial University and Kyoto Imperial University, aims to be a world-renowned Centres of Excellence, and in face, the university has always been among the world leaders in the fields of engineering.The Department of Architecture and Building Science in Graduate School of Engineering at Tohoku University is the world-famous research institute, which research subjects include indoor environment and energy conservation in residential buildings , ventilation and indoor air quality, occupants heath and indoor environment, passive solar system performance and so on. 课题研究计划THE SCHEDULE OF THE RESEARCH PROJECT PLAN:Jan. 2009 - Feb. 2009, Investigate indoor air quality (in terms of the concentrations of particulates and CO2 as indicators) in Chengdu railway station.May. 2009 - Sep. 2009, Investigate indoor thermal comfort and air quality of the railway station building in Southwestern China (including Chengdu, Chongqing, Deyang and etc.).Oct. 2009 -, Abroad.Oct. 2009 - Dec. 2009 Adapt to Japanese life and study environment, and make a achievable plan as soon as possible and begin to learning. Jan. 2010 - Dec. 2010 Subject 1: Study low energy system (ventilation technology) and ventilaiton rates according to actual architecture.Jan. 2011 - Aug. 2011 Subject 2: CFD for application to built indoor environment.
