摘要
概要地叙述了换热设备污垢对发达国家经济所造成的损失。通过有无自动清洗技术的对比试验和实际测试 ,结合文献统计数据 ,对冷冻机组水冷器污垢引起的效率损失作出评估。在此基础上根据《中国机械工业年鉴》数据 ,从宏观上逐项分析评估水垢造成我国冷冻机组水冷器的设备费、运行水费和运行电费三方面的损失 ,总计达到每年 36亿元以上。因此 ,在水冷器中大力推广自动清洗技术具有十分重要的经济意义。
The paper briefly states the fouling costs of heat transfer equipment in developed countries.The experiments are conducted to compare the operating effects between with the new self-cleaning online technology developed by the authors and without any self-cleaning technology.The practical tests are done to measure the fouling costs of water coolers in refrigerating units and the economic results by using the new terhnology.Based on the above and combined with the statistical data from China Yearbook of Mechanical Industry,the additional equipment costs and operating costs including water rate and electricty rate are analyzed respectively in detail from the macro point of view.They total over $3 6billion every year.Therefore,it is of great significance to spread widely the application of the new self-cleaning online technology.
