4、gineering科研課題背景介紹BACKGROUND OF THE RESEARCH PROJECT:The indoor environment quality of bus station building, subway station building, railway station building, airport terminal building and so on has attracted extensive attention increasingly, as the uncertain factors, peoples density, peoples mobili

5、ty, peoples stay time, tending to be influenced by weather and so on.A large number of the railway station buildings in China operate air-conditioning system in summer or even in the moderate summer climate. Therefore, the energy consumption and cost of these transportation buildings are considerabl

6、e. 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

7、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研究課題在國內外研究情況及水平THE CURRENT RESEARCH CONDITION AND LEVEL OF THE RESEARCH PROJECT AT HOME AND ABROAD:1.

8、here 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. A

9、lthough 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

10、 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 te

13、lation 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 investig

16、he 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
