摘　　要：近年来,在“碳达峰、碳中和”的大背景下,国家及地方各级政府颁布了一系列节能降耗、降碳减排的政策,推动能源绿色高效智慧转型,促进可再生能源高质量发展。太阳能、热泵等可再生能源作为生活热水系统的热源具有清洁环保、节能低碳、可持续获取的优势,近年来在民用建筑的生活热水系统中得到了广泛的应用。以宜兴市某住宅建筑的集中式太阳能+空气源热泵热水系统为例,制定了系统运行控制策略,详细介绍了系统精细化设计思路及过程。对比传统燃气、电力能源,寿命期内能源费用比燃气节省55.33万元,比电力节省77.33万元,节能及环境效益明显,减少了烟尘、CO_(2)、SO_(2)及NO_(x)的排放量,为可再生能源热水系统的深化设计及应用发展提供参考。In recent years,in the context of"reaching the peak of carbon and carbon neutrality",national and local governments at all levels have promulgated a series of policies on energy conservation,carbon reduction and emission reduction,promoting the green,efficient and intelligent transformation of energy,and promoting the high-quality development of renewable energy.As the heat source of domestic hot water system,renewable energy such as solar energy and heat pump has the advantages of clean environmental protection,energy saving,low carbon and sustainable access,and has been widely used in domestic hot water systems of civil buildings in recent years.Taking the centralized solar energy+air source heat pump hot water system of a residential building in Yixing City as an example,this paper formulated the system operation control strategy,introduced the system fine design ideas and processes in detail.Compared with traditional gas and electric energy,the energy cost during the life cycle is 55.33 yuan less than gas and 77.33 yuan less than electricity,and the energy saving and environmental benefits are obvious,reducing the emissions of soot,CO2,SO2 and NOx.This article providing a reference for the further design and application development of renewable energy hot water system.
