Abstract

In the context of sustainable development and increasing awareness of environmental protection, the manufacturing industry faces the dual challenge of improving resource efficiency and reducing environmental impact. This study aims to explore the optimization scheme of green manufacturing process through the combination of thermal efficiency optimization and life cycle assessment (LCA) technology, and promote the sustainable development of manufacturing industry. In this paper, a combination of experimental and theoretical analysis is used to first evaluate the thermal energy utilization rate in the current manufacturing process and identify the existing energy waste. Subsequently, the thermal efficiency was improved by introducing an improved heat recovery system and optimizing process parameters. Using LCA technology, the environmental impact assessment of the manufacturing process before and after optimization is carried out to quantify the effect of the optimization measures. Studies have shown that through thermal efficiency optimization, energy consumption in manufacturing processes is reduced and greenhouse gas emissions are significantly reduced.

基于热效率优化和生命周期评估技术的绿色制造工艺优化研究

在可持续发展和环保意识不断增强的背景下，制造业面临着提高资源利用效率和降低环境影响的双重挑战。本研究旨在通过热效率优化与生命周期评估（LCA）技术的结合，探索绿色制造工艺的优化方案，促进制造业的可持续发展。本文采用实验分析和理论分析相结合的方法，首先评估了当前制造过程中的热能利用率，找出了存在的能源浪费现象。随后，通过引入改进的热回收系统和优化工艺参数，提高了热效率。利用生命周期评估技术，对优化前后的制造过程进行环境影响评估，量化优化措施的效果。研究表明，通过热效率优化，生产过程中的能耗降低了，温室气体排放量也显著减少。

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
