Abstract

In this study, the performance of two renewable energy systems, ground source heat pump (GSHP) system and air source heat pump (ASHP) system, was analyzed through dynamic energy simulation, and carbon emissions were quantitatively calculated through a life cycle assessment method based on the simulation results. The carbon emissions of the energy systems were calculated by dividing the life cycle evaluation stage into four categories: production, construction, operation, and disposal, and the calculation of carbon emissions in the operation stage was based on the annual performance analysis of the dynamic energy simulation. For 1 year of operation, the GSHP system had 14% higher carbon emissions than the ASHP system, while for 20 years of operation, the ASHP system had 39% higher carbon emissions than the GSHP. Compared to the ASHP system, the GSHP system can reduce carbon emissions in the operating stage by 42% per year by securing higher COP, and within 2 years, the carbon amount in the entire process can be lower than in the ASHP system.

基于动态能量模拟的地源和空气源冷热系统碳排放分析
本研究通过动态能量模拟分析了地源热泵(GSHP)系统和空气源热泵(ASHP)系统两种可再生能源系统的性能,并基于模拟结果,通过生命周期评估方法定量计算了碳排放量。将能源系统生命周期评价阶段分为生产、建设、运行和处置四类,计算能源系统的碳排放量,运行阶段的碳排放量计算基于动态能源模拟的年度绩效分析。运行1年,地源热泵系统的碳排放量比地源热泵系统高14%,运行20年,地源热泵系统的碳排放量比地源热泵系统高39%。与源热泵系统相比,地源热泵系统通过确保更高的COP,每年可减少42%的运行阶段碳排放量,并且在2年内,整个过程的碳量可低于源热泵系统。
