Design of Renewable Energy Hot Water System for a Civil Building
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.
