【英文篇名】 Power consumption comparison of air cooled and water cooled chiller units 【作者中文名】 王树俊; 【作者英文名】 By Wang Shujun; 【作者单位】 化工部第四设计院; 【文献出处】 暖通空调, HV 水冷冷水机组; 装机容量; 耗电量; 负荷; 【英文关键词】 air cooled chiller unit; water cooled chiller unit; unit capacity; power consumption; load; 【摘要】 认为比较两者的耗电量应明确机组装机容量与耗电量的区别及负荷分布对机组效率和耗电量的影响。经比较得出，风冷机组耗电并不比水冷机组高多少，且其总运行费用可能还略低于后者。 【英文摘要】 Argues that for justifying the comparison it is of importance to differentiate the installed capacity from the power consumption and to allow for the effects of load profiles on the chiller unit efficiency and power consumption. Concludes that the air cooled unit would use not noticeably more energy than that by the water cooled unit, for the variation of load rate through the whole cooling season, and may be even lower in total operation costs.
