The heat pump system utilizes shallow geothermal energy in the coastal areas, which not only uses clean energy but also contributes to energy conservation and environmental protection. This paper studies the performance of a heat pump system applied a capillary heat exchanger as an energy collection device. The numerical performance of capillary heat pump showed a good agreement with the experimental data in the winter heating mode and the summer cooling mode. It was concluded that the COP of the heat pump unit using the capillary heat exchanger was 5.32 in winter and 4.32 in summer.
