基于不同面积比例的屋顶光伏光热系统设计

为降低高校建筑的能耗，设计了一种空气源热泵辅助式屋顶太阳能光伏光热系统。光伏组件和集热器的安装面积不仅会对电力侧产生影响，还会影响热力侧。首先建立系统的基本架构，然后以日运行费用为优化目标，使用改进的鲸鱼算法对系统进行优化，最后以乌鲁木齐某高校一宿舍楼为例，对光伏光热系统的环境及经济效益进行分析。算例结果表明，宿舍楼屋顶在安装满足最优比例的光伏光热系统的情况下，系统在环境保护和投资回收期方面都具有显著效益，切实达到了节约能源、减少二氧化碳排放和保护环境的目的。

Design of Rooftop Photovoltaic Solar Thermal System Based on Different Area Ratios

In order to reduce energy consumption of university buildings, a comprehensive system of rooftop photovoltaic system and air-source heat pump-assisted rooftop solar thermal system is designed. Not only the power sides, but also the thermal test will be affected by the installation area of photovoltaic modules and collectors. Firstly, the basic structure of the systems was established. Secondly, the system with daily operating costs was set as optimization target, and the system was optimized by using the improved whale algorithm. A dormitory buildings of university in Urumqi was taken as an example to analyze the environmental and benefits of the system. The results of the calculation example is shown that when the dormitory building roof is installed with a system that meets the optimal ratio, the system has significant benefits in terms of environmental protection and investment payback period. And the goals of saving energy, reducing carbon dioxide emissions and protecting the environment has been effectively achieved.
