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

夏季的浓雾影响了东北海道(太平洋沿岸)的气候。此外，这个地区冬天有很多晴朗的日子。本研究的目的是探索日光浴室在气候条件较好的地区的使用效果。在本报告中，根据测量结果和问卷调查结果，描述了日光房的热效应。第一章描述了研究的背景、目的和对象区域。对有日光房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。通过对调查结果的分析，证实了对日光浴室的满意度是比较高的。许多拥有大型日光房的居民实际上通过实际生活中的体验感受到了四季良好的热舒适性和冬季的节油效果。第三章在此基础上描述了日光室对室内温度和湿度的影响。在浓雾出现的季节，有大型日光室的房间具有良好的热效应。而且，冬季日光室内的温度与室外的温差往往超过20度。用聚乙烯薄膜制作的实验日光室有遮阳屋顶和裸露地面。第四章介绍了该日光室的温湿度控制实验结果。据了解，遮阳屋面降低了室内温度，而露天则增加了湿度。据猜测，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.
