Ground Source Heat Pump System Based on Residential Building.

Based on the climate conditions in the Gisborne region of New Zealand, this paper analyzes the economy and environmental protection of ground source heat pumps (GSHP) by simulation. The results show that GSHP can effectively achieve indoor heating function in winter and has a high coefficient of performance. That means more heat output per unit of electricity. This highly efficient energy conversion reduces energy consumption; more importantly, no combustion process is involved, so no harmful emissions such as combustion exhaust gas are produced. This helps to reduce carbon emissions and mitigate climate change.
