| Summary: | The energy bus system is a low carbon thermal energy system that can make integration of renewable energy sources or untapped energy sources for district heating and cooling. A small energy bus system was constructed by combining ground soil and surface water as low grade energy. The models of components in the system were developed according to theoretical analyses and test data of manufacturer, and the whole system was constructed by connecting various components on TRNSYS platform. The hourly and annual thermal performance of the system was simulated when it was applied to the Jinmao Chong Ming low-carbon experiment community . The result shows that the annual thermal coefficient of performance of the system is 3.5, while the thermal coefficient of performance for conventional systems is less than 1.5. Both energy saving rate and carbon reduction rate of the system are more than 20%. It can be seen that comprehensive benefits of renewable energy use and energy recovery are achieved in energy bus system. |
