【摘要】：服装热阻是热舒适研究中十分重要的物理参数,直接影响人体对热环境的要求,但我国现有的热舒适标准中没有给出服装热阻计算的方法,而ASHRAE Standard 55与ISO_7730等国际标准中对服装热阻的计算也存在一定差异,并不能有效适用于我国的服装热阻预测和热舒适研究。针对上述问题,本文对我国常见的服装热阻进行了测量,并比较了不同的成套热阻计算方法,并通过已有现场调查数据进行验证,探寻适合现场调查使用的服装热阻计算方法。首先,根据国际及国内的服装热阻测试标准,确定服装热阻测试方法。对大量服装的单件热阻进行测试,结果表明,与国际标准中相近服装测试结果相近。为使数据库可以适用于中国的热舒适现场调查,本次测试还包含了部分国际中不包括的具有“中国特色”的服装,例如秋衣秋裤、厚睡衣睡裤及毛裤等。其次,使用相同的测试方法对一些成套服装进行了测试。发现现有服装热阻测试标准,对于成套热阻测试规定有缺陷,不同测试间差异较大。在测试过程中,发现并验证了服装内部空气层及暖体假人块间传热对测试所得服装热阻值的影响。建议根据对服装热阻计算精度要求而选择不同的成套服装热阻计算方法。而后,利用不同方法表征受访者的着装量,分析了不同地区不同建筑类型的受访者的着装情况。发现不同建筑类型会对使用者着装产生不同的要求,这可能导致使用者对环境的需求也产生变化;不同地区的冬季室内着装差异明显,也可以体现出建筑使用者们对当前环境的需求差异。在对现场调查的数据分析中还发现着装件数与成套服装热阻间存在线性关系,可利用已有数据确定不同地区不同建筑中不同着装件数所对应的服装热阻,之后的现场调查通过统计着装件数就可以大致确定服装热阻。本文测试的单件服装热阻数据、不同气候区着装情况的数据及对不同成套热阻计算方法的探讨,能为我国热舒适相关标准的完善提供理论基础数据支持。
[Abstract]:Is the thermal resistance of clothing thermal comfort is very important in the study of physical parameters, directly affect human on the thermal environment, but the current thermal comfort standard has not given the clothing thermal resistance calculation, ASHRAE Standard 55 and ISO_7730 and other international standards on clothing thermal resistance calculation there are some differences, and clothing thermal resistance prediction not suitable for our country and thermal comfort research. Aiming at the above problems, this paper made a survey of the Chinese common clothing thermal resistance, and compared the different sets of thermal resistance calculation method, and verified by the field investigation data, explore the calculation method for thermal resistance of clothing field investigation used. First of all, according to the international and domestic the clothing thermal resistance test standard, determine the clothing thermal resistance test methods. Test on single resistance results show that a large number of clothing, clothing and similar international standard test results Similar. The database can be applied to Chinese thermal comfort field investigation, this test also includes part of the international was not included in the "China characteristic" clothing, such as long johns, thick pajamas and Maoku. Secondly, using the same test method has been tested on some sets of clothing. The existing clothing thermal resistance test standard, a complete set of defects on the thermal resistance test, different test greatly. During the test, found and verified the influence of air layer inside the clothing and manikin block heat transfer between the test the garment thermal resistance. The proposed calculation method and the choice of different sets of clothing thermal resistance according to the desired accuracy of the thermal resistance of clothing. Then, using different methods of characterization of the clothing respondents, analyzed the dress of different types of buildings in different regions of the respondents. Different types of buildings to make the discovery Use dress have different requirements, which may lead to the user demand for the environment changes; the winter indoor dress in different region is obvious, can also reflect the differences in building users demand in the current environment. In the analysis of field survey data also found the number of complete sets of clothing and clothing thermal resistance between the linear relationship exists clothing, thermal resistance can be determined with different dress number of different building in different areas corresponding to the existing data, after the field survey by statistics the number of dress will largely determine the clothing thermal resistance. This paper tests the thermal resistance data of a single piece of clothing, dress in different climatic region data and calculation methods for different sets of thermal resistance, can provide a theoretical basis for the data support for the perfect comfort related standard heat of our country.
