| 摘 要： | 为降低集中空调机组不断增长的能耗及其所引发的环境问题,我国制订了单元式空调机和冷水机组能源效率标准.我国标准将空调产品的能效水平分为5个等级,等级5为能效限定值、等级1能效最高、等级2为节能评价值.与美国标准对比,发现我国标准在国际上处于较低水平.以中、美两国标准来衡量我国集中空调机组产品的能效水平,发现多数集中空调机组能达到我国标准的限定值要求,但离美国标准和我国标准的节能评价值要求仍然有较大差距.

| Abstract: | In order to decrease the energy consumption of central air conditioning units and associated environmental issues, china has established energy efficiency standards for unitary air conditioners and water chillers. Chinese standards divide energy efficiency levels into 5 grades. Grade 5 is the minimum allowable value of energy efficiency; grade 1 represents the highest efficiency; grade 2 is the evaluating values of energy conservation. Compared with US standards, Chinese standards are in relatively low level in the world. When evaluating the energy efficiency levels of air conditioning units in China by Chinese and US standards, it can find most units meet the minimum allowable values of energy efficiency of Chinese standards, but few tally with the requirements of US standards and the evaluating values of energy conservation of Chinese standards. |
