The main work and the originality points of this dissertation could be concluded as the following parts:(1) To analyze systematically the mathematical model of LES of air flow in great space, under the case of isothermal and non-isothermal, as well as the combined action of buoyancy and strain. Some basic problems are studied about the LES application into airflow simulation of great space, such as boundary conditions, spatial difference scheme and time advancing scheme, time step etc., which creates the basis for the LES application to indoor airflow simulation.(2) Both the instantaneous and time averaged flow field of great space with multiple jets under isothermal and non-isothermal cases are explored with large eddy simulation method, and also discussed the dynamic characteristics and the law of fluidflow in the great space.(3) Based on the results of LES of the great space and the Fanger thermal comfort indexes, it is brought forward the concept of the series of dynamic thermal comfort evaluating indexes, which could be divided into thermal comfort index with time averaged properties PD, PPD, PMV, thermal comfort index with instantaneous properties IPD, IPPD, IPMV, and time averaged thermal comfort indexes TAPD, TAPPD, TAPMV, and transient situations time averaged thermal comfort indexes TTAPD, TTAPPD, TTAPMV. The differences among them and the calculation methods are discussed, and the four kinds of indexes are calculated with the thermal comfort index PD as an example.(4) Based on the LES results it is discussed the hot air stratification phenomena in air-conditioned buildings in the case with air supply and return registers on the ceiling and the case on the sidewall. The fundamentals of the hot air stratification are studied and the relations of estimating hot air stratification are brought forward.(5) With the advanced apparatus such as hot wire film anemometer IFA300 and laser particle field anemoscope, corresponding model test and site measurements have been done, which are compared with the simulation results and LES is proved a very promising method in air flow simulation indoor.

本文主要工作既创新点体现在以下几个方面：(1)系统分析了等温、非等温和考虑剪切力与浮升力综合作用的高大空间大涡模拟数学模型，并研究了高大空间大涡模拟在室内气流仿真应用中的一些基本问题，如边界条件、空间离散格式和时间推进格式、时间步长选择等问题，为大涡模拟在室内气流计算中的广泛应用打下了基础；(2)首次用大涡模拟方法研究了高雷诺数下高大空间多射流在等温、非等温情况下的瞬时流场和时均流场分布，并探讨了多射流流场的动态特性和流动规律；(3)基于大涡模拟的动态仿真结果和Fanger的热舒适指标，首次系统地提出了动态热舒适评价指标体系的概念：即基于时间平均参数的热舒适指标PD、PPD、PMV；基于瞬时参数的瞬时热指标IPD、IPPD、IPMV；基于时间平均热舒适指标TAPD、TAPPD、TAPMV；以及沿行动迹线的时间平均热舒适指标TTAPD、TTAPPD、TTAPMV，并分析了四类热舒适指标的差异性和计算方法，还以PD值为例对四类指标分别进行了计算；(4)基于数十种工况下空调房间大涡模拟的结果，研究了空调建筑上送上回和侧送侧回两种情况下热分层现象，并探讨了热分层的基本规律，首次提出了避免热分层现象的判断公式；(5)在暖通空调领域，首次使用IFA300热线风速仪、激光粒子速度场仪等先进设备，完成了与大涡模拟相对应的模型试验，并把实测结果与仿真结果进行了对比，说明LES在室内气流仿真方面是一种很有前景的方法。

For every room of different functions,such as bar, lobby bar, restaurant, banquet hall, and so on covering a large space chooses entire air system.it can get air of better quality and can run in the tansition seasons with all fresh air , which can make best use of natural energy and save energy.

针对各房间的位置和功能不同，酒吧、大堂吧、餐厅、宴会厅等大空间采用了全空气系统，房间空气品质较好，并且在过渡季节可以实现全新风运行，最大程度上利用自然界的能量，节省能源。

The room was small but clean, with an oak wardrobe, a dressing-table and mirror, and a chest-of-drawers, as well as the large casiron bed steads with a photo at its head and a very weak watercolour of sunset on the Pyamids over the chest-of-drawers

房间虽小，但却干净利落。房间有一个栎木的大衣橱，一个带镜子的梳妆台，一个五斗柜，还有一张铸铁架子的大床，床头嵌着一幅照片，五斗柜上挂了一张夕阳掩映金字塔的淡色水彩画

A Little Boy How I never could be tired with roaming about that huge mansion, with its vast empty rooms, with their worn-out hangings, fluttering tapestry, and carved oaken panels, with the gilding almost rubbed out---sometimes in the spacious old-fashioned gardens, which I had almost to myself, unless when now and then a solitary gardening man would cross me---and how the nectarines and peaches hung upon the walls, without my ever offering to pluck them, because they were forbidden fruit, unless now and then,---and because I had more pleasure in strolling about among the old melancholy-looking yew-trees, or the firs, and picking up the red berries, and the fir-apples, which were good for nothing but to look at ---or in lying about upon the fresh grass, with all the fine garden smells around me---or basking in the orangery, till I could almost fancy myself ripening too along with the oranges and the limes in that grateful warmth-or in watching the dace that darted to and Fro in the fish-pond, at the bottom of the garden, with here and there a great sulky pike hanging midway down the water in silent state, as if it mocked at their impertinent friskiness,---I had more pleasure in these busy-idle diversions than in all the sweet flavors of peaches, nectarines, oranges, and such like common baits of children.

I guess on his side of the house, the light comes barrelling through the blinds at 4 a.m.. I feel pretty bad for the guy but I don't think I'm going to crack. In our house back in California, Mike's bedroom has a fireplace, a 50 inch flatty, a jacuzzi bathtub with a chandelier over it, and a closet so big you could do wind sprints.

我猜他那间房间，早上四点就照到阳光了，哎，同情归同情，我可不打算让~~我们加州的家里，他的房间有59英寸大，还有火炉、按摩浴缸，他的衣柜大得都可以在里面跑步了。

Khadunm's chambers were directly across the hall, and, after being awoken by a loud crash and the sound of scuffling in his friend's room, he grabbed his new mace and silently entered the room, prepared for the worst.

哈顿穆的房间就在大厅的正对面，当他被他朋友房间里很大的砸碎东西声音和打斗声音惊醒后，他很快的拿起他的新锤棍，悄无声息的进入了那个房间，心里面做好了最坏的准备。

Undoubtedly, in this case, what is true for one is truer still for a thousand, as a large house is not proportionally more expensive than a small one, since one roof may cover, one cellar underlie, and one wall separate several apartments.

无疑的在这里，凡是对一个人是真实的，对于一千个人也是真实的，正像一幢大房子，按比例来说，并不比一座小房子来得更浪费钱财；一个屋顶可以盖住几个房间，一个地窖可以躺在几个房间的下面，一道道墙壁更可以分隔出许多房间来。
