Allowing water phase change to release latent heat to provide heat for water source heat pump system can increase the running time of heat pump unit and reduce the use of auxiliary heat source. When water freezes and releases latent heat to provide heat energy for heat pump unit, its heat transfer process is more complex. This paper mainly studied heat transfer characteristics of ice-water phase change for a spiral coil heat exchanger. Firstly, the phase change process of water was studied experimentally. Then, the numerical model was established based on the experiments and the model was verified by the experimental data. Finally, the temperatures and liquid fraction in the heat exchanger container were studied by the verified numerical model.
