The Investigation on the Prevention of Vapor Condensation and Vapor Condensation Damage by Using Hygroscopic Materials in a Dwelling House.

现将1997年至1998年研究所得的新知识列举如下。1)建立了墙体粘贴保温材料或吸湿材料条件下住宅内温湿度预测计算系统。打开门，住宅中每个房间的温度和湿度都会发生很大的变化。结果表明，两者的蒸汽凝结性能差别很大。特别是与供暖房距离最远的非供暖房发生蒸汽凝结最多。3)在间歇加热的情况下，蒸汽凝结成为加热启动的危险。因此，为防止蒸汽凝结而进行的必要隔热和防潮的粘贴厚度比全天加热进一步增加。4)取下被保护的蒸汽屏障，打开门的房间内相对湿度的波动为…，如果采用隔热材料作为吸湿材料，吸湿效果将大大缓解。5)如果从防止蒸汽凝结的角度出发，利用吸湿材料的吸湿性和含湿能力，可以减少吸湿材料的粘贴厚度，以防止蒸汽凝结。6)虽然吸湿材料含水率总是有增减的变化，但考虑实际水汽凝结期（1月* 3月90天）的外源性天气波动时，中期含水率上升最多，90天后含水率下降。7)非加热房间吸湿材料的含水率高于加热房间。通过门的开度、方位角对非加热房间产生的差异以及改变吸湿性材料的粘贴厚度进行防汽凝坝的非常经济的检验是可能的。8)外部空气温度和湿度作为检查防汽凝损害措施的指标，采用平均温度和湿度可以进行合理的检查。少

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.
