【摘要】

：

本文采用快速关阀法对Φ7管窗片和波纹片换热器在不同冷凝和蒸发工况下的R410A制冷剂质量变化特性进行了实验研究,并验证了常用的7种空泡系数模型对换热器内制冷剂质量预测的适用性.实验研究结果表明,换热器用作冷凝器时,制冷剂质量随着冷凝温度的升高先降低后增加,随着过冷度的增加几乎呈线性增加的趋势,而基本不随换热器迎面风速的变化而变化;换热器用作蒸发器时,制冷剂质量随着蒸发温度的增加是明显增加的,受换热

膨胀型钢结构防火涂层耐湿热性能的理论分析与机理研究

为考察膨胀型钢结构防火涂层的湿热老化机理及在湿热环境下防火涂层防火隔热性能随使用时间的变化规律,对隔热性能试验的试验结果进行了计算和总结.并通过傅里叶红外光谱检测和炭化层结构的扫描电镜对U型、A型这2种膨胀型钢结构防火涂料进行了湿热老化机理分析.结果表明;涂层发生老化是由于涂层内的亲水性物质向涂层表面迁移和析出:U型、A型这2种涂层的等效导热系数随老化时间延长总体上均呈现出增大的趋势,且增幅与涂料
