The water-ice phase change heat exchanger is developed to solve the problems such as insufficient water sources,high cost of ground source drilling,unstable solar energy,high cost and no suitable low temperature heat source of heat pumps in mountainous rural areas of Hebei province.By using the latent heat of water phase change as the low temperature heat source of the heat pump,a coupled heat supply system of water-ice phase change solidification heat transfer and heat pump is designed.An experimental platform is built,and the test results show that the platform runs stably and reliably.Through the analysis and calculation of the experimental data,the coefficient of performance of the system is between 2.87 and 3.42.The research results can provide a reference for solving heating problems in mountainous rural areas of Hebei province.
