工厂自然通风的温度效应
Temperature effect of natural ventilation in factories
摘要：
基于多个试验结果，构建了自然通风系统特性的全信息图；提出了自然通风工程个案应用的简明有效算法；得到了自然通风车间热分布系数方程和自然通风流量算式。对热车间自然通风换气次数实测值与计算值进行了比较，验证了该算法的准确性。该算法为热车间内“双区分层流动”模式的应用提供了依据。
Abstract：
This paper reviews the research of phase change energy storage tanks in recent years, and classifies phase change energy storage tanks according to the appearance structure of the phase change energy storage tank, the installation method of the phase change material, the heat transfer mode and the arrangement mode of the auxiliary heat source. The thermal performance, influencing factors, research methods and experimental conclusions of the phase change energy storage tank are sorted and analysed, and the effects of different material structures and operating conditions on the performance of the phase change energy storage tank are summarized. The deficiencies of the current research on phase change energy storage tanks are pointed out.
Keywords:phase change energy storage tank; phase change material; heat storage capacity; heat storage time; thermal stratification;
