荒漠高速服务区建筑采暖节能分析

Energy Efficiency in Building Heating in Desert Highway Service Areas

以位于中国首条沙漠高速公路S21中部的克拉美丽服务区为研究对象,介绍了新疆荒漠高速公路服务区建筑采暖的现状,利用PVsyst模拟软件建立了光伏发电模型,研究了太阳能发电部分代替电网供电采暖实现节能的效果。结果表明:通过建立光伏系统模型,得出光伏组件最佳倾斜角为41°和最佳方位角为0°。设计太阳能板面积10 063 m2的光伏发电系统,系统装机容量为2 178.4 kW;采暖季发电量能够达到1 403 603 kWh,满足了该服务区采暖用电量需求,年碳减排量达773 t,年碳收益39 342元。

Taking the Clara beautiful service area located in the middle of China's first desert highway S21 as the research object,the current situation of building heating in the service area of Xinjiang desert highway was introduced,and the photovoltaic power generation model was established by using the PVsyst simulation software,and the effect of solar power generation partially replacing the grid power supply for heating to realize energy saving was studied.The results show that the optimal tilt angle of the PV module is 41°and the optimal azimuth angle is 0°by establishing the PV system model.The design of the solar panel area of 10063 m2 of photovoltaic power generation system,the installed capacity of the system is 2178.4 kW;heating season power generation can reach 1403603 kW·h,to meet the heating power demand of the service area,the annual carbon emission reduction amounted to 773 tons,the annual carbon gain of 39,342 yuan.
