The use effect of glass fiber cloth is affected by the change of indoor air temperature

"Human body temperature is basically stable, with a small range of change, and does not change with the rise and fall of the external temperature. According to the requirements of the average temperature of human skin (about 33~- 35C), the indoor air temperature in the indoor thermal comfort environment is in accordance with the standard requirements, the design index of heating in winter is 16~18C, and the design index of thermal environment in the air conditioning room in summer is 26~28C.

According to the basic limit value of the heat transfer coefficient of the wall according to the energy-saving design standard for the external wall of the building in different climatic zones.
External insulation of external wall During winter heating, the insulation layer with high thermal resistance increases the overall thermal resistance of the external wall, reduces the transfer of indoor heat through the external wall to the outside, and improves its thermal insulation capacity. In hot summer, the external thermal insulation layer with high thermal resistance has a small heat storage coefficient on the external surface and less heat transferred to the wall, effectively delaying the outdoor heat flow into the wall; On the other hand, the main structure layer of heavy material has high thermal inertia index and good thermal stability, giving people a feeling of "warm in winter and cool in summer".

Although the material composition of the internal and external thermal insulation is the same, the heat transfer coefficient calculated under the same conditions is the same, and the thermal inertia index is the same, the effect of the surrounding thermal bridge on the heat transfer of the whole wall is different because of the different insulation layer settings, so that the average heat transfer coefficient of the internal and external thermal insulation walls is different, and the heat storage coefficient of the internal and external surfaces is also different, resulting in completely different effects.
