Problems solved by technology

Although the energy-saving measures and energy-efficiency evaluation methods adopted so far have achieved remarkable energy-saving effects, most of these methods are limited to specific devices or processes, and the specific evaluation system is not perfect. The comprehensive energy efficiency evaluation system makes it difficult to give a more comprehensive and accurate evaluation of various energy-consuming equipment and their energy-saving effects, resulting in the lack of comprehensive and effective energy-saving solutions

[0007] To sum up, for the research on enterprise energy efficiency evaluation, a scientific and unified evaluation method system has not yet been formed. Many studies are limited to specific devices, processes or energy types, lacking systematicness and promotion, and truly scientific, effective and practical methods. There are even fewer enterprise energy efficiency evaluation systems and energy efficiency sensitivity analysis methods, and medium and large energy users such as high energy-consuming enterprises and energy-saving service companies have a strong demand for this aspect
