Study on Life Cycle Environmental Impact Assessment of Ground Resource Heat Pump Project

With the popularization and application of Ground Source Heat Pump (GSHP) technology and the expanding scale of shallow geothermal exploitation, the environmental impact in the process of development and utilization is receiving more and more attention. According-to the characteristics of ground source heat pump engineering, eBalance software is used to conduct research on life cycle environmental impact assessment. The result shows that more than 60% of resources consumption potential, acidification potential, and global warming potential derived from the process underground construction, and the eutrophication potential mainly derived from ground construction, underground construction, decommissioning with the contribution of 40.24%, 30.67% and 28.99%. According to the results, we put forward several reasonable control measures to ease the environmental impact in the process of geothermal exploitation and utilization for heat pump project.
