This research study reviews life-cycle assessments (LCAs) of solar water-heating systems (SWHS) and provides a complete overview of its progress. Several research papers have confirmed the advantages of SWHS in energy saving and environmental protection, but the reported system performances varied greatly, due to climate, raw materials and the systematic design. The environmental impacts are mainly caused by the manufacturing and acquisition of raw materials, whose values vary depending on the forms of the system and the materials. The users also have great influence on the performance, but there are few studies regarding this and optimisation should be made accordingly. LCAs highly depend on the implication background, including the energy structure and industrial production technologies. Whether to choose solar energy or not needs life-cycle analysis according to local conditions.

太阳能热水系统的生命周期评估:综述

本研究回顾了太阳能热水系统 (SWHS) 的生命周期评估 (LCA),并对其进展进行了完整概述。多篇研究论文证实了 SWHS 在节能环保方面的优势,但由于气候、原材料和系统设计的原因,报告的系统性能差异很大。环境影响主要来自原材料的制造和获取,其价值因系统形式和材料而异。用户对性能的影响也很大,但是这方面的研究很少,应该做相应的优化。LCA 高度依赖于蕴涵背景,包括能源结构和工业生产技术。
