heat exchange coefficient meaning in English
热交换系数
Examples
- This experiment include many contents , in a word , that is summer condition experiment , winter condition experiment > summer - winter transition condition experiment and winter - summer transition condition experiment , furthermore summer condition experiment still include flux changing experiment and winter condition experiment still include thermal balance experiment this article dealt with the data of the test , calculating out energy absorbing ( energy discharging ) of buried pipe in winter condition ( summer condition ) , input power of heat pump x heat exchanging of piece buried pipe length x co - efficiency performance ? op ( energy efficiency rate ? er ) and average heat exchanging coefficient ; in additiont this article compares the inlet water temperature and outlet water temperature of underground the first layer and the second layer buried pipe when heat pump was running , the results are that the heat exchanging ability of the second layer buried pipe outgos the first layer buried pipe , and heat exchanging is more stable ; and still analyse earth temperature resuming in the transition season . the results are earth temperature resume fast in the first week when the heat pump runs off
本文测试内容相当多，概括地说就是四个工况的测试，即夏季制冷工况的测试、冬季供热工况的测试、夏?冬过渡季测试和冬?夏过渡季测试；另外在夏季工况的测试中还进行了变流量测试，在冬季工况的测试中还进行了热平衡测试。本文对测试数据进行了处理，计算出了冬(夏)季工况埋管吸(放)热量、热泵空调器供热量(制冷量) 、热泵空调器输入功率、埋管单位管长换热量、供热性能系数(制冷能效比)和平均传热系数等；另外，还比较了热泵运行时地下一二层埋管进出水温度变化情形，得出地下二层埋管换热能力优于地下一层埋管，且换热很稳定；并分析了过渡季地下一二层埋管温度恢复情形，得出热泵系统停机一周内地温恢复特别快。 - In this paper , the study status about freeze - up of domestic and overseas was discussed first , then based on thermodynamic theories and river ice hydraulic theories , using the observed data to calculate parameters , the freeze - up forecasting mathematical model in inner mongolia reach was established . in the model , the calculating method of heat exchanging coefficient was perfected properly , and the river characteristics was quantified for the first time . the forecasting result indicated that the model precision is high , and the freeze - up forecasting formula is all - purposed
本文首先论述了国内外有关封河研究的现状，然后在此基础上针对存在问题，以热力学理论及冰水力学理论为基础，利用实测资料率定参数，建立了内蒙古河段封河预报数学模型，其中对热交换系数的计算进行适当的修改，并将河道条件量化考虑进封河预报数学模型中，证明预报精确度高，且各河段预报公式具有通用性。
