Research On Cost Efficiency And Selection Of Solar Energy Technology For Residential Buildings In Hot Summer And Cold Winter Area

At present,there are two ways to use solar energy technology in residential buildings in my country: the use of solar thermal technology and the use of solar photovoltaic technology.The selection of solar energy technology for different types of residential buildings usually only considers the initial investment,use and maintenance of solar equipment Convenience and other factors have caused the utilization of solar energy technology in residential buildings to be unreasonable,which prompted the author to do further research on the application of solar energy technology in residential buildings.For a certain type of residential buildings(low-rise,multi-storey,mid-high-rise and highrise residential buildings),whether to choose the use of solar thermal or solar photovoltaic,it is necessary to establish a life-cycle economic evaluation method.The selection of residential building solar energy equipment carries out quantitative economic analysis,so as to determine the utilization method of residential building solar energy technology according to the size of the economic benefits of the whole life cycle.This article attempts to apply the research method of life cycle cost efficiency to analyze the utilization of solar energy technology in residential buildings in hot summer and cold winter areas in China.First,according to the relevant theories of cost efficiency method and combined with the actual application of solar energy technology in residential buildings,the application The theoretical deduction method establishes the costefficiency model for the use of solar thermal technology in residential buildings and the costefficiency model for the use of solar photovoltaic technology in residential buildings,and then determines the parameters of the above models according to the characteristics of the climate and environment in the hot summer and cold winter areas in China,and then Apply the mathematical model of life cycle cost efficiency to analyze and calculate the solar energy technology utilization methods of low-rise residential,multi-storey and mid-high-rise residential buildings,and high-rise residential buildings,and finally determine the low-rise residential,multi-storey,and The solar energy technology utilization scheme of middle-and high-rise residential buildings and high-rise residential buildings will guide the selection of solar energy equipment for residential buildings.Through the research of this article,we have obtained the best way to use solar energy technology for different types of residential buildings(low-rise,multi-storey,mid-high-rise and high-rise residential buildings)in the hot summer and cold winter areas in my country,which is economical for the selection of solar energy equipment for residential buildings It provides a reference to make the application of solar energy technology in residential buildings more scientific and reasonable.
