| Abstract: | Aiming at the thermal defects of traditional biomass wall, an integrated pipeline biomass heat storage wall with solar energy as the heat source is proposed. By establishing a comparative experimental model, the physical parameters of the wall system and indoor environment were tested respectively to study the thermal efficiency differences between the two models, and the heating performance of the experimental wall system was analyzed. The results show that： the proposed integrated pipeline biomass wall system has excellent heat collecting and storage performance; the control strategy of pipe flow system should adapt to the local meteorological conditions to optimize the heating efficiency; the integrated pipeline biomass wall can reach the energy saving rate of 79.3% with significant economic benefits, which has the prospect of wide application in biomass and solar energy rich areas. |
