项目摘要

In this research, the effect of the environmental symbiosis technique which can be used is verified aiming at the proposal of the eco-house which was adapted for the climatology of a South Kyushu area.The results of work obtained by this research are summarized to below.1.The temperature and air current within the ventilation layer of an outside thermal insulation method of construction various kinds of experiment and measurement using a experimental house were performed for the purpose of grasp of quality.2.The experiment and simulation about the indoor environmental improvement effect by the ventilation which can set a summer were performed. The following results were obtained.□ According to the experiment with a model, the size of an opening and the solar shade of the surface of a wall influence the indoor warm temperature environment at the time of ventilation.□ According to simulation analysis by the case an opening is large enough, when not carrying out a right pair to a wind dir … More ection, the amount of ventilation can be secured.3.The following knowledge was acquired from measurement in the experiment with a model and the existing building at the time of applying a paint with the tow solar absorptive characteristic to a roof.□ From the experiment-with-a-model result of having applied various paints, it was checked by reducing solar absorptance on the surface of outside using a low solar absorptive paint that solar absorptive performance improves.□ The improvement effect in insulation efficiency of a low absorptive paint was not able to be checked. It is considered to be the cause that this has thin application thickness.4.In installation of the solar energy power generation system in a residence, the experiment and the simulation were performed about the influence the ventilation layer thickness on the back of a solar array panel affects module temperature. The obtained result is as follows.□ The thickness of the back of panel influences panel temperature.□ Although the cooling effect which a back ventilation layer has is increasing from 10mm to 150mm as for ventilation layer thickness, it does not change more than by it.

本研究针对适合南九州地区气候的生态住宅方案，验证了可使用的环境共生技术的效果。本研究取得的工作结果总结如下.1.外保温施工方法的通风层内的温度和气流在实验房内进行了各种实验和测量，以掌握质量。2.室内环境的实验和模拟可以设置通风的改善效果得到以下结果。 □ 根据模型实验，洞口的大小和墙体表面的遮阳对通风时的室内温暖环境有影响。 □ 进行模拟分析。在开口足够大的情况下，当不对风向进行正确的配对时，可以确保通风量。3.通过模型和现有建筑物的实验测量获得以下知识在使用涂料时屋顶的太阳能吸收特性良好。□ 从使用各种涂料的模型实验结果来看，通过使用低太阳能吸收涂料降低室外表面的太阳能吸收率，可以提高太阳能吸收性能。□无法检查低吸收性涂料的绝缘效率的改善效果，这被认为是其涂敷厚度较薄的原因。4.在太阳能发电系统的安装中。针对太阳能电池板背面通风层厚度对组件温度的影响进行了实验和模拟，得到的结果如下： □ 电池板背面厚度影响组件温度。背面通风层所具有的冷却效果从10mm增加到150mm，通风层厚度没有变化。
