Performance Evaluation of Ground Source Heat Pump System and Research on Carbon Emissions of the Whole Life Cycle of A University
In this paper,the performance evaluation of ground source heat pump system is carried out based on a university experimental base project.Taking economic benefit,technical performance and envi-ronmental performance as evaluation indexes,the comparison and analysis of air cooled and gas fired boiler system from aspects of life cycle cost,energy efficiency ratio and standard coal quantity are carried out.It is concluded that the ground source heat pump system has more advantages.The life cycle method is used to divide the life cycle of the ground source heat pump system into four stages:production,transporta-tion,installation,operation and maintenance and recovery.A carbon emission calculation model is estab-lished for each stage of the life cycle of the ground source heat pump system.The results show that the carbon dioxide emission is the largest in the operation and use stage of the ground source heat pump sys-tem,accounting for 96.85%.According to the calculation results,the coal-based power structure is ad-justed and promoted;the proportion of hydraulic power supply system is improved,and the carbon dioxide emissions is reduced during the operation of the ground source heat pump system.The research results provide reference for developing low carbon economy and promoting sustainable development from two perspectives of ground source heat pump system performance and carbon dioxide emission.
