Research On The Performance Of Heat Transfer Of New Transparent Insulation Solar Wall

Nowadays the energy problem has already become the main problem in the world. Theincreasing of building energy consumption results in not only increasing the energy nervous,but also increasing substantially the emissions load of CO2. This status threats to our survivalenvironment. Therefore energy saving is extremely urgent. As a kind of building palisadestructure form which makes full use of solar energy to heat, so the widespread use of the solarwall that adjusts measures to local conditions has important value and meaning.The paper analyzed the heat transfer theory of solar thermal storage wall, compared withthe transfer theory of different structure solar walls, and analyzed the influencing factor of theheat transfer process. At the same time, analyzed and compared with the materials of thedifferent structure solar wall. At last designed the new type of transparent insulation solar wallwhich this paper introduced. According to the theory of heat transfer, established the newphysieal and mathematieal model and given the size of the related structure. The paper usedthe CFD (numerical simulation) to analyze the air space of the new solar wall and simulateddifferent sizes of vents and different sizes of collection hot the height of the wall, thenconcluded the best size. This article mainly aims at the different climatic conditions in winterbetween the north and the south, then simulated and analyzed the heat transfer performance ofthe new solar wall. Through smulated calculation, given the temperature field and velocityfield of the air space and outlet of the new structure, then found both of the law. Smulated thetemperature of the heating room with the new structure changed with time in some day inwinter,then given the change rule of the average temperature indoor. At the last of thispaper,compared with two traditional structure solar wall, then given the feasibility andsuperiority of the new transparent insulation solar wall.
