针对博物馆展柜出现的在夏季高温工况时展柜内温度无法降到恒温恒湿系统设定值的现象,通过实验计算并比较玻璃导热产生的冷负荷和送风提供的冷量,来判断柜内温度达到要求所需要的最小风量,并计算出了展柜单层钢化玻璃在内外都是受迫对流换热状态时的传热系数K值。 Aiming at the phenomenon that the temperature inside the showcase can not be lowered to the setting value of the constant temperature and humidity system during the high temperature condition in summer in the showcase of the museum, the inside of the cabinet can be judged by experimentally calculating and comparing the cooling load provided by the glass thermal conductivity and the cooling capacity provided by the air supply The minimum temperature required to reach the required air volume, and calculate the single-story showcase glass inside and outside the forced convection heat transfer state when the value of K.
