This article on the different structure of solar wall collection hot regenerative heat and ventilation mechanism are analyzed, and the advantages and disadvantages of comparison between them, design the new structure of solar wall, if necessary, under the condition of establishing hypothesis solar wall heat transfer of the physical and mathematical model, the method of numerical simulation of new solar wall of heat and mass transfer properties have been studied.
The research content and conclusion: the solar wall system heat transfer basic theory, the paper analyzes the different structure of solar wall, analyzes the advantages and disadvantages of solar wall system heat transfer process, and then design factors affecting the new structure of solar wall, build a new solar wall of physical and mathematical model, and related parameters were determined, For new solar wall between the air layer is simulated and analyzed vents size, collection hot wall height and vent to inquire whether have shutter collection hot wall between air layer air temperature and velocity of air influence; According to the north and the south in winter winter climate condition, of new solar wall of heat and mass transfer performance is simulated and analyzed, and in the light of the northern summer climate condition, to solar wall summer ventilation performance simulated points. Given collection hot wall temperature field, air between layer velocity field and the outlet, analyzes the distribution of temperature and velocity distribution regularity of, For new solar wall winter heating the diurnal variation condition are simulated, and gives different day moment collection hot wall temperature field and the air layer between the distribution of velocity field, and gives shutter collection hot plate and outlet air outlet average temperature and average flow velocity changes in law; For new solar wall system heating room temperature field simulation, give indoor temperature field distributions, and the indoor temperature, changes are analyzed, the indoor average temperature changes in law; With a contrast analysis method is validated new solar wall is effective and feasible.
