A new knowledge got by the research in the 1997 year 1998 year is enumerated in the following.1) Calculation system of the prediction of temperature and humidity in the dwelling house was established under the condition that the insulating material or hygroscopic material was affixed in the wall.2) By opening the door, the temperature and humidity of each room in a dwelling house greatly changes. As the results, the vapor condensation property greatly differ. Especially, the vapor condensation is most occurred in non-heating room which is separated from the heating room in the distance most..3) It becomes the danger in the heating start for the vapor condensation in case of intermittent heating. As the result, the affixing thickness by necessary thermal insulation and moisture proof for the prevention of vapor condensation increases further than all day heating.4) The protected vapor barrier is taken off, and the fluctuation of relative humidity in the room where the door is opened is … More greatly eased by the hygroscopic effect , if the heat insulating material is utilized as the hygroscopic material.5) The affixing thickness of hygroscopic material can be decreased from that of thermal insulation material for the prevention of vapor condensation, if the hygroscopicity and capacity of moisture content of hygroscopic material is utilized in the viewpoint of prevention of the vapor condensation.6) Though there is always increase and decrease on moisture content in the hygroscopic material, when externality weather fluctuation in actual vapor condensation period (90 days in January * March) is considered, and the moisture content in the middle period rises most, and it decreases after 90th.7) The moisture content of hygroscopic material in the non-heating room is higher than that of the heating room. The very economical examination that the difference produces even in the non-heating room by door open, azimuth and that it changes hygroscopic material pasting thickness for the vapor condensation dam age prevention is possible.8) As the outside air temperature and humidity for examining the prevention measures of vaporcon densation damage, the reasonable examination is possible by using the average temperature and humidity.

通过1997 ~ 1998年的研究，获得了以下新的认识：1）建立了在墙体上粘贴保温材料或吸湿材料的情况下，住宅内温湿度预测的计算体系; 2）打开房门，住宅内各房间的温湿度发生较大变化。结果表明，不同的冷凝性能差别很大。尤其是与采暖室距离最远的非采暖室，其蒸汽冷凝现象最为严重。3)在间歇加热的情况下，蒸汽冷凝成为加热启动中的危险。其结果是，与全天供暖相比，通过必要的隔热和防潮来防止蒸汽冷凝的粘贴厚度进一步增加。4）被保护的蒸汽屏障被移除，并且门打开的房间中的相对湿度的波动被消除。 ...更多信息 如果使用绝热材料作为吸湿材料，则吸湿效果大大减轻。5）吸湿材料的附着厚度可以从绝热材料的附着厚度减小，以防止蒸汽冷凝，如果从防止蒸汽冷凝的观点出发，利用吸湿材料的吸湿性和含水量的能力。6）尽管吸湿材料中的含水量总是有增加和减少的情况，但在实际蒸汽冷凝期间，当外部天气波动时，（1月 * 3月90天）考虑，中期含水量上升最多，7）非采暖室内吸湿材料的含水率高于采暖室内。即使在非加热室中，也可以通过开门、方位角等来产生差异，并且可以通过改变吸湿材料的粘贴厚度来防止蒸汽冷凝损害，这是非常经济的检查。8）作为检查蒸汽冷凝损害的预防措施的外部空气温度和湿度，可以通过使用平均温度和湿度来进行合理的检查。少
