Simulation analysis of household solar assistant radiant floor heating system in cold area

This study analyzed the performance of household solar assistant radiant floor heating system in cold area (taking Jinan as an example). Solar assistant radiant floor heating system models, including solar radiation model, collector model, thermal tank model and underground coil radiation heating model, were established in MATLAB Simulink. Based on the theoretical and simulation calculation, the optimal installation angle of solar collectors in different seasons and operating performance of the system under different parameters were obtained. The simulation results provide reference and guidance for the design and operation parameters of solar assistant radiant floor heating system in cold area in the future, and plays a certain role in promoting the application of this kind of primary energy saving system.
