Research On The Performance Of Heat Transfer Of New Solar Wall

Solar wall is the key technology that solar energy is collected and accumulated and the important component that we carry out integration of solar——building integrated. And it is also a topic that scholars of the world are concerning and studying. So the research of solar wall has very important significance.The paper represented the heat transfer theory of solar thermal storage wall, and designed new structure of the solar wall, established the new physical and mathematical model, and the related parameters were determined; Carried on the numerical simulation to the new solar thermal storage wall's air intercalated bed, analyzed impact of the vent size, the wall's height and vents with louvers on the air temperature of solar wall's air layer and air velocity; And in view of the north and south climatic conditions in winter, simulated and analyzed the heat transfer performance of the new wall, and in view of the north summer's climatic conditions, simulated and analyzed the ventilation properties of the wall in summer. Given figures of the heat storage wall temperature field, air velocity between the field and the distribution of the outlet, analyzed the distribution of the temperature and velocity field; Simulated the diurnal variation condition of the new type of solar wall heating in winter, given the distribution graph of the temperature and air velocity field at different times of the day, and given the mean temperature between collector plates and outlet louvers,and the variation regulation of outlet air's mean velocity variation; Simulated the heating room's temperature field of new type of solar wall system, given the distribution of indoor temperature, and the daily variation of indoor temperature was analyzed,given the average indoor temperature variation; confirmed the new solar thermal storage wall feasibility and superiority with the method of contrastive analysis.
