新型轻质建筑保温材料的广泛应用,使采暖能耗大为降低,但同时也产生了一些新问题,其中之一,就是室温波动过大,容易恶化室内热环境,影响人们的正常使用,这一问题已引起了人们极大的关注。产生室温波动的原因是多方面的,但室外气温、太阳辐射等的不断变化是其主要原因。目前,为了减小室温波动,主要的作法就是增加外墙的热阻。事实上,窗的耗热量(包括渗透)要比外墙的大,而且对温度波幅的衰减也小得多,显然,室外气象变化通过窗引起的室温波动比通过墙引起的室温波动要大。因此,单纯地附加外墙热阻是很难达到 The wide application of new lightweight building insulation materials has greatly reduced heating energy consumption, but at the same time it has also created some new problems. One of them is that the room temperature fluctuates too much, which can easily deteriorate the indoor thermal environment and affect people’s normal use. One issue has caused great concern. There are many reasons for the fluctuation of the room temperature, but the constant change in outdoor air temperature, solar radiation, etc. is the main reason. At present, in order to reduce the room temperature fluctuations, the main method is to increase the thermal resistance of the external wall. In fact, the window’s heat loss (including penetration) is greater than that of the exterior wall, and the attenuation of the temperature amplitude is also much smaller. Obviously, the room temperature fluctuation caused by outdoor meteorological changes through the window is greater than the room temperature fluctuation caused by the wall. Therefore, simply adding the thermal resistance of the external wall is difficult to achieve
