摘要：
Low-carbon building is an important scenario to achieve carbon peaking and carbon neutrality goals under the new development philosophy in China. Based on this, a low-carbon building heating system (LCBHS) driven by photovoltaic power generation and semiconductor radiation heating, and its operation strategy were proposed in this work. Firstly, simplifying and making equivalent to the heat transfer in envelope structure and radiant heat transfer, a physical model was established based on the semiconductor radiation heating. Then, considering the uncertainties of photovoltaic power generation and heating demand, a photovoltaic energy supply system was constructed. Furthermore, the operation strategies of heating and energy supply for the LCBHS were presented. Finally, a simulation analysis was carried out for the whole system in Simulink. The results show that the LCBHS possesses a faster heating response and a lower operation temperature compared with the traditional grid powered heating system. In addition, taking the heating season of Wuhan as example, the carbon emission and corresponding heat cost during the heating season are reduced by 43.01% and 47.85%, respectively. Moreover, when concerning the benefits and impacts of transferring the electricity generated by the photovoltaic system to the grid, the reductions of carbon emission and heating cost are more significant. The decrease of carbon emission can reach to 73.9% and the heating cost can be reduced by 76.48%. © 2023 Beijing Institute of Technology. All rights reserved.
