西北某新建厂区多能耦合绿色供能优化设计与分析

Optimization Design and Analysis of MultiEnergy Coupling Green Energy Supply in a New Factory Area in Northwest China

我国地热能、太阳能和空气能等资源丰富,进行可再生清洁能源多能耦合、优势互补、综合利用,成为我国能源转型升级的新方向。通过对我国西北某新建厂区基础条件及项目用能需求进行分析研究,提出了经济合理、绿色低碳的“浅层地源热泵+太阳能光热+空气源热泵”多能耦合绿色供能综合开发利用优化设计。结果表明:项目所在区资源丰富、项目供能技术可行,建成后可节约运行费用111.4万元/a,项目静态增量回收期为9.67a、内部收益率为9.95%,长期经济效益、环保效益和社会效益显著。研究为我国西北区域多能互补综合绿色供能提供了基础依据。

China has abundant resources such as geothermal energy,solar energy,and air energy.The coupling,complementary advantages,and comprehensive utilization of renewable and clean energy have become a new direction for China's energy transformation and upgrading.This paper studies the basic conditions and energy demand of a newly built factory in northwest China,and proposes an economically reasonable,green and low-carbon "shallow ground source heat pump + solar thermal + air source heat pump" multi energy coupling green energy supply comprehensive development and utilization optimization design.The results show that the project area has abundant resources and feasible energy supply technology.After completion,it can save 1.114 million yuan/a in operating costs.The static incremental payback period of the project is 9.67 years,and the internal rate of return is 9.95%.The long-term economic,environmental,and social benefits are significant.The research provides the basis for the green energy supply in the northwest of China.
