玻璃窗配百叶窗后传热系数的实验研究

EXPERIMENTAL STUDY OF HEAT TRANSFER COEFFICIENTS OF THE GLASS WINDOW WITH A VENETIAN BLINDS

对单双层玻璃窗室内配百叶窗后的传热系数进行了测定。考虑了百叶窗叶片角度变化对传热系数的影响。根据实验结果得出了经验关系式,并对窗框和环境风速的影响作了修正。

The heat transfer coefficients of the glass window with a Venetian blinds are investigated experimentally. Two types of window systems are measnred which are the double glazing with an inner Venetian blinds and the single glazing with an inner Venetian blinds. The effects of the blade angles on heat transfer coefficients are also tested. From the experimental data, empiric equations are derived. The effects of window frame and ambient wind velocity on the coefficienfs are considered.
