Therefore, the method based on the energy consumption per unit of product cannot be used to evaluate and compare the energy efficiency levels of different enterprises
[0005] Energy consumption per unit of output value refers to the ratio of industrial comprehensive energy consumption to total industrial output value during the statistical period. It is an indicator that considers the energy efficiency level of enterprises from the perspective of economic value. In the same statistical period, the energy efficiency of enterprises in the same industry can be evaluated For enterprises in different industries, this indicator cannot be used to evaluate their energy efficiency level

[0076] Taking copper smelting enterprises and yellow phosphorus enterprises as examples, the total equivalent energy saving is calculated according to the energy consumption of the enterprise during the statistical period, and the energy efficiency evaluation of the enterprise is carried out according to the equivalent energy saving. Among them, copper smelting enterprises produce two products: anode copper and industrial sulfuric acid. The enterprise’s energy consumption report for the production of anode copper, as attached figure 2 shown. Yellow phosphorus enterprises only produce one product, yellow phosphorus, and the energy consumption data are obtained directly from the enterprise database.
[0077] Step 1: Calculate the comprehensive energy consumption per unit of product
[0078] Step 1.1: Calculate a certain amount of energy consumption based on enterprise metering system data or energy reports.
[0079] Energy consumed to produce copper anodes includes coal, gas...

The invention discloses an enterprise efficiency evaluation method based on the equivalent energy saving amount, which comprises the following steps: step one, the comprehensive energy consumption per unit product is calculated; step two, the equivalent energy saving amount of per unit product is calculated; step three, the total equivalent energy saving amount of an enterprise is calculated; and step four, efficiency evaluation is performed on the enterprise. Concepts of the equivalent energy saving amount per unit product and the total energy saving amount of the enterprise are introduced, sorting or rating is performed on the efficiency level of enterprises is performed according to the size of the total equivalent energy amount of each enterprise, and cross-industry inter-enterprise efficiency evaluation is realized.
Description
technical field [0001] The invention relates to a cross-industry inter-enterprise energy efficiency evaluation method that takes into account the energy consumption index of a unit product, and belongs to the field of soft measurement. Background technique [0002] At present, the indicators for evaluating the energy efficiency level of enterprises mainly include energy consumption per unit of product, energy consumption per unit of output value, and electricity consumption per unit of product. [0003] Energy consumption per unit of product is the average amount of various energy actually consumed in the production of a certain product, that is, the ratio of the comprehensive energy consumption of the product to the output of the corresponding qualified product. This indicator can be used to compare similar products and enterprises using the same process. Energy efficiency evaluation. However, for enterprises in different industries and in the same industry but with differ...
