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

夏季浓雾影响了北海道东部（太平洋沿岸）的气候。此外，这个地区冬天有很多晴朗的日子。本研究的目的是寻找日光房在具有这种气候的地区的有效性。在本报告中，根据测量结果和问卷调查，描述了日光房的热效应。第一章阐述了本文的研究背景、目的和研究对象区域。对有阳光房的住宅的居民进行了热环境问卷调查。第二章报告了本次调查的结果。通过对这一结果的分析，确认了对日光房的满意度是比较高的。很多拥有大型日光房的居民在实际生活中体会到了四季良好的热舒适性和冬季节油的效果。两栋独立住宅的温度和湿度测量分别在冬季和夏季进行。第三章根据这一结果描述了日光房对室内温度和湿度的影响。在大雾出现的季节，大型日光房的热效应得到了证实。而且，在冬季，日光房内的温度与室外的温度之差经常超过20度。一个由聚乙烯薄膜制成的实验性日光房有遮阳屋顶和暴露地面。第四章描述了该日光房的温湿度控制实验结果。据了解，室内温度因遮阳屋顶而降低，湿度因暴露地面而增加。推测日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.
