Study on the thermal performance of solar wall

By analyzing the heat transfer process, a CFD model for simulating the dynamic thermal performance of reformative solar wall was presented and solved by coupling the heat transfer in solid region with the viscosity fluid. Under the typical winter and summer meteorologic condition of North China, the thermal performance of heat collection,heat preservation, heat insulation, pre-heating were discussed. In addition, the suitable construction and material for solar wall were given by analyzing the sensitive factors such as material, height, thickness of air gap,width of ventetc. The conclusions drawn in the paper will promote the development of the technology for build integrating solar and thermal.
