研究目的
To test the heat transfer and refrigeration effect of the monomer structure of semiconductor cold wall in net-zero energy buildings (NZEB) and to propose improvements for NZEB in hot summer and cold winter areas.
研究成果
The monomer structure of semiconductor cold wall has certain cooling effect but the heat exchange effect is not good only through natural convection and radiation heat transfer. Strengthening the heat transfer at the ends of the semiconductor refrigeration piece can improve the cooling effect. Adding superconducting hot nanometer plate and ensuring good insulation can solve the cooling efficiency issues.
研究不足
The heat exchange effect is not good of the cold and hot aluminum plate only through natural convection and radiation heat transfer. Further study is needed on the process of semiconductor refrigeration and heat transfer and the factors that affect the cooling effect.
