蒸发式冷凝器压缩机能耗及换热性能实验研究

Experimental Study on Compressor Energy Consumption and Heat Transfer Performance of Evaporative Condenser

为进一步研究压缩机能耗及蒸发式冷凝器换热性能,本文采用对比实验的方法,研究了冷凝器进风温度,进风湿度以及喷淋水量等因素对空冷与蒸发式冷凝器的压缩机能耗及换热性能的影响。通过研究表明,冷凝器进风空气湿度对压缩机耗功量的影响较小,而压缩机耗功量随进风温度的增加而增加,随喷淋水量增加呈先减小后增加的趋势,喷淋水量在不同的进风温度工况下存在最佳值,蒸发式冷凝器管外复合换热系数随进风温度的增加而递减,随喷淋水量增加而增大。

In order to further study the compressor energy consumption and the heat transfer performance of the evaporative condenser,by using the method of comparative experimental study,the influence of the condenser inlet air temperature,inlet air humidity and spray water volume on the energy consumption and heat exchange performance of the compressor of the air-cooled and evaporative condensers is analyzed.The results show that the condenser inlet air humidity has little influence on the compressor power consumption.The energy consumption of compressor increases with the increase of inlet air temperature and decreases first and then increases with the spray water volume.The spray water volume has the best value under different air inlet temperature conditions.The composite heat transfer coefficient outside the evaporative condenser decreases with the increase of the inlet air temperature,and increases with the increase of the spray water volume.
