Analysis Of Porous Solar Wall Thermal Characteristics And Application

Porous Solar wall is a new type of solar heating technology, and that the system iscomposed of two parts by the collector and air transport. The solar wall panels cover theoutside of the exterior walls and walls to maintain a certain distance, the air flow between thesolar panels and the exterior walls. Solar wall panels manufactured by the1-2mm thickgalvanized steel or aluminum. The outer coating has a strong absorption of solar heat, UV-blocking function. The color is generally black and other dark.This paper first describes the utilization of solar energy principles, characteristics, anddomestic and international research status, and Porous Solar wall construction, the use ofnumerical simulation methods to analyze the structure and thermal properties of the solar wall,and finally the application of solar wall structure to optimize the design demonstration andanalysis.This paper analyzes the sun wall height, spacing, and the location of the outlet the samecircumstances, to change the number of solar wall holes, changes in indoor air parameters.The number of holes in the sun wall, spacing, the location of the outlet the same case, changethe height of the solar wall, indoor air parameters change; and the number of holes in the sunwall, the height of the outlet the same location, change the spacing of the solar wall, indoorair parameters change. The results show that, to improve the indoor air supply may beappropriate to increase the small hole number; general sun height of the wall to take themaximum height, that is, the external wall height of; solar wall spacing should not be toolarge, generally less than0.2m and other conclusions.Finally, the numerical simulation of heat transfer and flow through the common roomwith porous solar room, the comparison of the two room temperature distribution and flowfield distribution, analysis of the reasons for the different results. Existing porous solarbuilding window area has been simulation and improved. The results show that the PorousSolar wall room thermal comfort than ordinary room. Design optimization of the solar wall,increasing the area of the solar wall, indoor thermal comfort improve. Improved roomwindow to wall ratio of0.303, windows floor area ratio of0.2, in line with the requirementsof energy-efficient buildings.
