太阳能是目前最丰富的可再生能源,在发电、取暖、供水等方面取得了广泛应用。本文根据作者实际工程经验并结合国家规范要求,针对当前建筑太阳能热水系统的给排水设计方面进行了分析和总结。太阳能既是一次能源,又是可再生能源。太阳能资源丰富,既可免费利用,又无需运输,对环境又无任何污染。如何合理、有效利用太阳能技术,已成为不可改变的趋势。在国家大力提倡低碳环保的前提下,住宅太阳能热水系统开始大量应用在新建住宅上面。因此,如何合理进行建筑太阳能 Solar energy is currently the most abundant renewable energy and has been widely used in power generation, heating and water supply. Based on the author’s actual engineering experience combined with the requirements of national norms, this paper analyzes and summarizes the water supply and drainage design of the current solar water heating system. Solar energy is both primary energy and renewable energy. Solar energy is rich in resources, which can be used freely and without any need of transportation, and without any pollution to the environment. How to use the solar energy technology reasonably and effectively has become an unchangeable trend. In the country to promote low-carbon environment, under the premise of residential solar water heating system began to be widely used in new residential buildings above. Therefore, how to conduct rational construction of solar energy
