The authors analyzed the low flow circulation ground source heat pump system, which has the variable water volume control in the primary side, in the office building. It is confirmed that the electric power of circulation pump was reduced as 85% compared to the constant water volume. The difference between the system COP including the circulation pump and the heat pump COP was small. Additionally, the effect of energy saving compared to the conventional air source heat pump system was 33%.
