标题:烟气生成的数学模型在“舱房概念”设计中之应用
关键字:
内容:由于建筑上和功能上的原因,大型的交通枢纽大楼,常常需要设计成无隔火墙的大型空间,“舱房概念”就是从防火和防烟的漫延而发展起来的。排烟系统是舱房概念中不可缺少的组成部分。抽气率应相等或大于烟气的生成速率。在实际设计中,有许多烟气生成的数学模型应用于计算烟气的生成率。于是人们质疑甚么数学模型应用于计算烟气的生成率。于是人们疑甚么数学模型可应用于设计以及数学模型的可靠性能。本文的主旨是探讨四个烟气生成的数学模型并与试验数据作比较。探讨结论发现这四个模型的计算结果没明显的区别,并且计算结果与试验数据相符。
标题:Energy Saving Designs of HVAC Systems for Tomson Shanghai International Club
关键字:
内容:
An energy study was carried for a clubhouse to be built in Shanghai. The total plot area of the projectis approximately 80000 sq m2, with approximately 24000 sq m2 of which being iterior design area that reqired different forms of HVAC services. When completed , the clubhouse will provide services with social, business and entertainment functions. Conservation of energy was a high priority for the design of the project. In consideration of this , Ove Arup & Partners untilized energy simulation technology to study the feasibility of introducing the most advanced building enrgy-efficient engineering ractices to the project.
The study started with the understanding of climatic conditions. it is found that both heating and cooling are necessary to provide a high quality of indoor environment . Reduction on energy consumption replies on the proper selection of systems for generation and distribution of cooling and heating energy. A series of studies on systems such as ice storage, desiccant cooling and dehumidificiation , adsorption chiller, heat-reclaim devices, solar system and combined heat and power system were carried out. This paper presents the results of some of these studies, with both technical and edonomics considerations being investigated.
标题:Reducing duct sttic pressure in Variable,air-volume(VAV)Air Conditioning Systems for fan power saving
关键字:
内容:This paper presents two field studies for the energy performance of VAV air conditioing systerms when duct static pressure was reduced. The first one was based on manual reset of duct static pressure whilst the second based on a recently developed DDC scheme using the summation of air flow rate passing through each VAV box as the control signal. In both studies, significant fan power saving has been achieved.
标题:Natural Ventilation Design by Computational Fluid Dynamics A Feng Shui Approach
关键字:
内容:Feng Shui is a study of natural sicence. It tries to incorporate physics, geography , climatology, astronomy, aerodynamics, fluid dynamics and electromagnetics together and produces something for divination. The basic concept of the ancient Chinese is that human beings must live in harmony with the earth and the heaven, i.e. the whole universe. In order to make sure we are in harmony with the universe, we need to rely on the rules of Feng Shui to do the best. Most Chinese believe in Feng Shui to a certain extent although quite a large number of them are reluctant to admit it openly, afraid of being criticised at superstition. In Hong Kong , many architects refer to Feng Shui rules when they are designing buildings, in particular ,domestic buildins to achieve a better image and of course a higher price. The geometrical relation ship between critical areas within a flat, say the toilets and the kitchens, and the bedrooms has been considered one very important element for the good Feng Shui of the flat. We believe that it is something to do with the air flow within the flat, which is invisible and difficult to measure. In this paper , techniques in computational fluid dynamics(CFD) are employed to look into this aspect of Feng Shui. The theory of CFD and the calculation procedures are briefly introduced. An example wil be included as an illustration.
标题:AIR-CNDITIONING SYSTEM DESIGN FOR A METRO STATION-A GENERAL OVERIEW
关键字:
内容:
Many major citiese around the world are facing severe traffic congestion problems and the associated air pollution problems brought about by vehicles moving along densely populated areas. Governments of these major cities are considering construction of underground metro systems to alleviate the problems for their communities.
The air-conditioning system is a vital system of an underground railway. Not only is it necessary to control the environmental condition during normal operation, for passenger comfort, what is equally important is the need for the system to control the smoke propagation in case of a fire occurring inside the station. This is to ensure that safe evacuation means is provided to the passengers when a fire breaks out at the station or on the train.
