混凝土电气加热蓄热冷却计算理论的研究

A research into cooling calculation theory of concrete's thermo electric-storage

本文在吴震东教授提出的非大体积混凝土蓄热冷却理论的基础上，对混凝土电气加热的时间Ｚ和加热过程中平均温度ｔｐ的计算，依据不稳定传热理论，从瞬时动态角度出发，考虑实际影响电热蓄热的主要因素，提出广义的混凝土电热冷却定律，建立电热蓄热平衡微分方程，从而解得整套理论公式。电热蓄热微分方程可应用于非大体积混凝土冬季电热法的蓄热设计，也可应用于大体积混凝土的冬季电热法的蓄热设计，因此表面系数Ｍ可不受限制。

In this article,basing upon The previous documents.if has introduced the concrete's thermo electric storage time z and its average temperature t, during its thermo electrie-storage processing.According to the theory of unstable thermal conductivity, starting from an angle off instantaneous activity and deliberating the main effective factors of actual concrete's therrmo electric-storage, It has derived the synthetic cooling law of concrete's thermo electric storage. and deduced the thermo electric differential equation.and established eventually the whole set of these theoretical calculation formulas.The thermo electric-storage differential equation may be used for calculation of a massive as well as a non-massive comcrete's thermo electric-storage during winter construction. while its surface coefficient M may not be restricted.
