Study on Temperature and Humidity Control by Sunroom in Region covered with Dense Fog

夏季的浓雾影响了北海道东部（太平洋沿岸）的气候。此外，这个地区的冬天有很多晴朗的日子。本研究的目的是探讨日光浴室在该气候地区的有效性。本报告在测量和问卷调查的基础上，对阳光房的热效应进行了描述，第一章介绍了研究的背景、目的和对象区域。第2章报告了这项调查的结果。当对这一结果进行分析时，证实了对日光浴室的满意度相对较强。许多拥有大型日光房的居民在实际生活中感受到了四季良好的热舒适性和冬季的节能效果，并对两栋带有日光房的独立式住宅进行了冬夏两季的温湿度测量。第三章在此基础上分析了日光房对室内温湿度的影响。结果表明，在浓雾季节，大型阳光房具有良好的热效果。而且，在冬季，日光室内的温度与室外的温度之差往往超过20度。一个用聚乙烯薄膜制成的实验日光室有遮阳屋顶和裸露的地面。第四章介绍了利用该太阳房进行温湿度控制的实验结果。据了解，室内温度降低的遮阳屋顶，和湿度增加的暴露地面。据推测，阳光房地面的防潮对控制室内湿度是有效的。

The dense fog in summer influences in the climate in the East Hokkaido (in Pacific Ocean coast). Moreover, there are a lot of clear days in winter in this region. The purpose of this research is to search for the effectiveness of the sunroom in the region with such a climate. In this report, a thermal effect of the sunroom is described based on the result of the measurement and the questionnaire survey.The background, the purpose, and the object region of the research are described in Chapter 1.The questionnaire survey of the thermal environment was done for the resident in the house with the sun-room. It reports on the result of this survey in Chapter 2. When this result was analyzed, it was confirmed that the satisfaction with the sunroom was comparatively strong. A lot of residents who had a large-scale sunroom were actually feeling the good thermal comfort in all seasons and the effect of the fuel reduction in winter by the experience in actual life.The measurement of temperature and humidity in two detached houses built with the sun-room was done in winter and summer. The effect of the sunroom on the temperature and the humidity in the house was described based on this result in Chapter 3. A good thermal effect on the room with a large-scale sunroom was confirmed in the season when the dense fog appeared. And, the difference between the temperature in the sunroom and the outside temperature often exceeded 20 degrees in winter.A experimental sunroom made with a polyethylene film has the shading roof and the exposure ground. The result of experiment of the temperature and the humidity control with this sunroom is described in Chapter 4. It has been understood that the indoor temperature decreases by the shading roof, and humidity increases by the exposure ground. It was guessed that the dampproof of ground in the sunroom was effective for the control of humidity in the house.
