Research Abstract

Field tests were carried out at four locations of various geological settings to enhance the heat exchange rate at ground heat exchangers in ground source heat pump systems by generating artificial groundwater flow, i.e., cross flow or water injection. The field tests showed that the cross flow and the water injection of approximately 5 L/min remarkably enhance the heat exchange rates. A sensitivity study using a groundwater simulator showed that the excessive water injection rate wastes water resources and the injection rate of 1-5 L/min is ,ost cost-effective. The study also showed that the temperature of the injected water should be close to the ground temperature to improve the energy efficiency.
