How to resolve the coupling problem between the air quality and the indoor thermal environment, especially how much fresh air can assure the indoor air quality, how to design control system to satisfy the need of fresh air, and how to track the change of the air quality in the civil air defence underground engineering at real time were studied thoroughly in this paper.

摘 要 本文就如何解决人防工程内空气品质和工程内热湿环境的耦合性问题进行一定研究，尤其对人防地下工程需要多少新风量才能满足工程内空气环境品质；如何设计控制系统以满足工程内的新风需求；如何实时跟踪工程内空气品质的变化进行了深入研究。

Regional development occupies large land, develops lots of contents, relates to multifields including industry, construction, business and civicism, so it is necessary to identify its influence on nature environment such as air, groundwater quality, surface water quality and hydrological condition, sound, soil, plants, topographty and social environment such as population, traffic, economic structure. The countermeasures of carring through circular economy, controlling pollution sources, planning industrial structure scientifically, distributing reasonably, implementing cleaner production and total quantity control should be taken to promote regional sustainable development.

区域开发具有较大的不确定性，并且占地面积大、开发的内容广、性质复杂、建设周期长，通常的区域开发都有可能涉及到工业、城建、商业、人居、市政等多个领域的开发活动，所以区域开发必须结合区域开发的特征，准确识别其可能对区域内及其周边的空气环境、地下水质量、地表水水质及水文条件、声环境、土壤、植被、地形地貌等自然环境和人口、交通、经济结构等社会环境等产生的影响，并采取发展循环经济，减少污染生成的源头控制措施；科学规划产业结构，合理布局的预防性措施；源内达标、区域集中控制的污染治理措施；实施清洁生产、总量控制，推进区域环境与经济的持续发展。

The 1967 amendments to the Clean Air Act of 1963 (1967 Air Quality Act) provided the first comprehensive federal scheme for air pollution control.

1967年的条例对1963年净化空气条例的修改(1967 年空气质量条例)提供了第一个关于空气污染控制的全面的标准的方案。

After taking those factors, such as stable combustion and reducing pollutant emissions into account, the following operation parameters are recommended: combustion temperature between 850℃ and 860℃, excess air coefficient of 1.35, secondary air fraction 40% and mass mixing ratio 30%.

综合考虑稳定燃烧和降低污染物排放等因素，得出一系列最佳燃烧参数。燃烧温度应该控制在850~860℃，过剩空气系数应该控制在1.35左右，二次风率应该控制在40%左右，质量掺混比应该控制在30%左右。

In order to find the main factors which affect the indoor air quality of newly decorative residences, orderly to prevent and control the diseases and hazardousness caused by indoor air pollutants scientifically and rationally, almost 200 newly decorative residences in Chengdu have been tested in the year of 2007, and these measurement results vs. different seasons, different type of buildings and different ventilation time have been compared and analyzed in detail.

为了掌握影响新装修住宅空气质量水平的主要因索，更加科学合理地预防和控制室内空气污染带来的疾病和危害，对2007年度成都市200余户新装修住宅的室内空气进行了检测，并按照不同季节、房间类型、通风时间进行了详细地比较和分析。

Pass and export the passway in the form of information, send out and control the order in time , control the opening and stopping of the press, operation and conversion , Stone of valve of air blower movement, in order to realize automatic control in central air conditioner is it go on the regulation of the air to the air conditioner room to come.

以信息的形式通过输出通道，及时发出控制命令，控制压机的启停，风机的运行和四通阀的转换等动作，以实现对中央空调的自动控制来对空调房间进行空气调节。

At last the paper realized the advantages and disadvantages of passive solar building and adnvanced some suggestions in future research. From another point, the paper logged the process of the building of the experimental equipment and the mounting of the measurement equipments that accumulated some operating experimence.Carrying experiments, calculating and analyzing the experimental data for more than 2 years, the paper gained some constructive conclusions. In winter the indoor air temperature and RH are lower than comfort criteria, but people feels very comfortable in the passive solar house. The thermo-circulation formed by Trombe wall play an important role in improving indoor air temperature and RH. Based on the analogy analysis theory, the natural convection heat transfer in the air gap can be treated as superposition of two natural convection heat transfer processes occurring over isolated isothermal vertical flat plate, in this case namely the massive wall and glazing. Two empirical formulas for Q and Nu are obtained. The investigation shows that the optimal time to open the damper should comply with the period that the thermo-circulation happens which can be controlled by thermal response characteristics of Trombe wall surface temperature and air temperature in the air gap.

经过两年多的实测和计算，根据传热学、流体力学、统计学等学科的基础理论，对大量数据进行整理归类、分析讨论，主要得到如下结论：(1)冬季，含有特朗贝墙体的被动式太阳房室内热湿环境较舒适性标准偏低，但人体感觉比较舒适，特朗贝墙体形成的热循环通风在调节室内温度和相对湿度方面起到很大的作用；(2)特朗贝墙体空气间层自然对流可以看作是两个等温独立大平板的自然对流换热过程的叠加，通过与大平板自然对流理论类比获得了计算热循环过程中对流换热量的经验公式；(3)特朗贝墙体通风口的启闭可以根据玻璃幕墙内壁面温度、蓄热墙体外壁面温度和空气间层进出口空气温度之间的关系来进行控制，从而有效地阻挡冬季冷循环的发生；(4)夏季，如没有有效的通风降温措施，被动式太阳房内会产生明显的过热。
