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.

Indoor air sources of formaldehyde are mainly in the following aspects : 1, the plywood used for interior decoration, Ximugongban, medium density fibreboard and shaving board, and other artificial plate because formaldehyde has strong sexual bond, has strengthened plate and the hardness control, corrosion functions, Therefore, the current production of imitation board use Jiaonianji merits to formaldehyde as the main ingredients thiourea aldehyde resins, plate, residual and did not participate in the response formaldehyde will gradually release of the surrounding environment is a indoor air formaldehyde main ;2, using imitation board manufacturing furniture, some manufacturers in the pursuit of profit, the use of unqualified plate. In preliminary front face material reuse inferior glue, the manufacturing processes are not standardized, as a result of customers buying home, to buy a small emission points ;3, containing formaldehyde content and may distribute to the outside other categories decorative materials, such as stickers Qiangbu, with wallpapers, chemical fiber carpet, foam, paint and paint, etc.;4, combustion, emit formaldehyde certain materials, such as cigarettes and some organic materials.

室内空气中的甲醛来源主要有以下几个方面：1、用作室内装饰的胶合板、细木工板、中密度纤维板和刨花板等人造板材，因为甲醛具有较强的粘合性，还具有加强板材的硬度及防虫、防腐的功能，所以目前生产人造板使用的胶粘剂是非曲直以甲醛为主要成分的脲醛树脂，板材中残留的和未参与反应的甲醛会逐渐向周围环境释放，是形成室内空气中甲醛的主体；2、用人造板制造的家具，一些厂家为了追求利润，使用不合格的板材，在粘接贴面材料时再使用劣质胶水，制造工艺不规范，结果顾客买回家去，等于买回了一个小型废气排放站；3、含有甲醛成分并有可能向外界散发的其他各类装饰材料，比如贴墙布，贴墙纸，化纤地毯、泡沫塑料、油漆和涂料等；4、燃烧后会散发甲醛的某些材料，比如香烟及一些有机材料。
