Energy Efficiency Rating是指什么呢？？

这个意思是能效率的等级，这里说none就是能效率很低，不环保

刚刚上Domain的网站上去看了一下,Energy Efficiency Rating下写的是Not available.
Energy Efficiency Rating是能源效率评估值,有一个California Home Energy Efficiency Rating System美国加州家庭能源有效性评级系统.
Energy Efficiency Rating：none就是能源有效性没有评估的意思.

EER is an abbreviation for Energy Efficiency Rating. The Air-Conditioning and Refrigeration Institute（美国空调与制冷协会） standardized this rating, which reports central air conditioning efficiency at 80 degrees F indoors and 95 degrees F outdoors. This rating measures steady-state efficiency -- that is, the efficiency of the air conditioner once it is up and running.

The SEER (Seasonal EER) rating is available for residential central air conditioners, and is generally considered a more reliable indicator of the overall energy efficiency of the unit than the EER.
