Abstract

Groundwater source heat pumps, as a renewable energy technology, are widely used in refrigeration and heating of buildings in China. To improve the efficiency of heat pump systems, delaying thermal breakthrough has become a key focus. In this study, based on the groundwater source heat pump project at the Shenyang Institute of Instrument Science, a numerical model of the groundwater source heat pump extraction system was established using FEFLOW software. The research explores the changes in the underground temperature field in the presence of thermal breakthrough caused by the existing expanded water source heat pump and compares the degree of thermal breakthrough under different well layout methods at the Institute of Instrument Science. The results show that during system operation, the degree of thermal breakthrough is weakest and has the least impact when well layout option two is employed for extraction wells, and the well group layout method determines the distribution pattern of the underground temperature field.
