我国房间空调器与家用电冰箱的能效评价与分析

The evaluation and analysis on the energy efficiency of room air conditioners and refrigerators in China

对我国房间空调器进行了能耗分析 ,并从寿命成本周期LCC、投资回收率PBP及环境方面进行了节能方案的技术经济分析和比较 ,发现要降低改进措施的LCC和PBP ,必须降低空调器的制造成本 ,并将环境因素考虑在内以提高对环境造成影响的运行成本。分析了我国家用电冰箱的能源限定值和能效等级分析 。

In this paper, the energy consumption of the room air conditioners in China is analyzed. The energy conservation methods are analyzed and compared technically and economically from the view points of LCC, PBP and environment. We find that the manufacture cost of the air conditioner must be decreased and the operation cost considering the influence on environment should be increased in order to reduce the LCC and the PBP of the improvement design products. In addition, the limited energy value and the energy efficiency label of the refrigerators are analyzed and the methods of improving the energy efficiency are provided.
