Optimization Design and Analysis of MultiEnergy Coupling Green Energy Supply in a New Factory Area in Northwest China
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 di-rection for China's energy transformation and upgrading.This paper studies the basic conditions and energy de-mand 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 ba-sis for the green energy supply in the northwest of China.
