摘要
目前我国综合食品加工企业都使用单位产值的能耗量或能耗费用来衡量能耗的程度,由于这种指标没有反映出使用水平、营业水平和质量水平对企业能效的影响,所以在企业之间能效比较时难以作出正确评价。文章以实例列举出国内外有代表性的大型综合食品加工企业的能耗现状进行对比;分析了目前企业使用的能耗评价指标在横向比较、评价时出现错误的原因;提出了可反映使用水平、营业水平和质量水平新的能效评价方法,对国内六家有代表性的企业进行能效评价,结果显示企业之间能效差异十分显著,节能降耗提高能效成为企业迫切需要解决的问题。
At present, food production factories in our country evaluate energy consumption level by using energy consumption per unit production or energy consumption fees. However, these indices do not reflect the influence of the using level, business level, and the quality level on the enterprise energy efficiency. In this study, energy consumption situation of some food production factories at home and abroad were compared, and the problems caused by the current energy consumption evaluation indices were analyzed. A new energy efficiency evaluation index which can reflect using level, business level, and the quality level was proposed. Then the evaluation of energy efficiency for six representative domestic food production factories was performed with the present index. The result shows that energy efficiency difference among factories is obvious.
