水冷式表冷器传热研究(8):热力计算理论及其研究综述【英文篇名】 Heat transfer study on water-cooled surface air coolers (8): thermodynamic calculation theory and its research review 【作者中文名】 王晋生; 程宝义; 龙惟定; 【作者英文名】 By Wong Jinsheng; Cheng Booyi and Long Weiding PLA University of Science and Technology; Nanjing; China; 【作者单位】 解放军理工大学; 同济大学; 【文献出处】 暖通空调, Hv 热力计算; 理论; 综述; 【英文关键词】 surface air cooler; thermodynamic calculation; theory; review; 【摘要】 水冷式表冷器热力计算理论包括干、湿、半干半湿工况的热力计算方法、工况判别方法、相关术语的定义及热工实验方法。对各部分研究现状作了综述。指出干工况热力计算方法已较成熟;湿工况热力计算方法以建立在等价干工况基础上的方法综合评价较好;半干半湿工况因把湿状态段转换为等价干工况处理而取得进展;国内目前使用的工况判别方法不及ASHRAE推荐的或卡尔波斯提出的工况判别方法;以等价干工况为理论基础的热工实验方法使表冷器实验得到简化。分析了干工况和湿工况的总传热系数实验公式的表达形式。 【英文摘要】 The thermodynamic calculation theory of water-cooled surface air coolers includes thermodynamic calculation methods (TCMs) of fully wetted, partially dry, and completely dry cooling conditions, method of judging work conditions, definitions of relative terms and thermodynamic testing method. Reviews present research status. Points out that the present TCM of dry cooling conditions is mature; that the TCM of wet cooling conditions based on the equivalent dry cooling condition (EDC) is synthetically the best;...
