Abstract :
The recent work focuses on the hydronic snow-ice melting and classifies the structure of module and physical model for the further numerical simulation, and strengthens theoretical understanding. The example results show that in Changchun city, the north eastern of China, under the condition of the statistical weather data from historical record, a normal heat consumption rate in the snow-ice melting was about 246W/m2 and COP (coefficient of Performance) of heat pump unit was over 4. It is recognized that, when the ground heat exchanger is used for heating, the heating will result in a gradual drop of the ground thermal equilibrium temperature or the initial underground temperature of next heating season annually. As a result, by using the support of the seasonal UTES with solar collecting, the underground temperature can be increased. Therefore, the solar collection actually supplements the thermal energy to the ground and provides a sustainable development.
