蒸气压缩式集中空调机组能效的探讨
Discussion on energy efficiency of central air conditioning units with vapor compression cycle
摘要：
介绍了美国、中国大陆及台湾地区的集中空调机组的能效标准。对中国大陆市场上集中空调机组的能效水平进行了统计分析，发现大多数产品的能效水平高于GB/T18430.1-2001的能效限定值，但与发达国家的要求还有不小差距，有必要适当提高现有的能效限定值。

Abstract：
Presents energy efficiency requirement of central air conditioning units of US and the Mainland and Taiwan of China. Analyses the unit efficiency of the Mainland products. The results show that the real values of energy efficiency of most products are higher than the minimum allowable value required by GB/T 18430.1-2001 but under the demand of developed countries. It is necessary to improve the related energy efficiency standards.
