强热源工业厂房室内对流辐射特性分析
Characteristics analysis of convection and radiation in industrial plants with high temperature heat source
摘要：
测试了西安某热轧厂房夏季和冬季的室内温度、风速以及辐射热强度等参数。结果显示：夏季工况室内平均温度超过35 ℃，冬季工况室内平均温度低于10 ℃；冬季工况室内平均风速高于夏季工况；夏季工况和冬季工况的室内辐射热强度的变化趋势基本一致，但夏季工况的定向平均辐射温度高于冬季工况，而且远远高于室内空气温度。

Abstract：
Tests the characteristics of indoor temperature, air velocity and radiant heat intensity of a steel hot rolling plant in Xian during summer and winter. The results show that the average indoor temperature is over 35 ℃ in summer and below 10 ℃ in winter, the average indoor air velocity in winter is higher than that of in summer, the variety of radiation intensity in summer is compliant with that of in winter, but the direction mean radiant temperature in summer is higher than that of in winter, and the direction mean radiant temperature is far higher than the indoor air temperature.
