Thermal Parameter Designing Research And Experimental Data Analysis In Passive Solar House With Convective Collecting Heat Wall

A passive solar house provides cooling and heating to keep the home comfortable without the use of mechanical equipment. It is designed to collect, store and distribute the sun's heat in winter; and to block the sun's rays in summer according to the characteristics of the building and the surrounding environment. It also has particular internal and exterior physical characteristics, ingenious color design and the felicitous combination of raw materials.Although the technology of the passive solar house is already basically mature. It is still unknown in domestic that the simple calculating method of thermal parameter designing and the heat cycle of this convective collecting heat system about this kind of collecting heat wall. This paper was resourced from the Inner Mongolia nature science fund project,"Thermal Parameter Designing Research and Experimental Data Analysis in Passive Solar House with Convective Collecting Heat Wall". In this paper, I established the heat transfer mathematic model under unstable states and the heat cycle mathematical model on the basis of theoretic study. Furthermore, I established the dynamic regression equation between heat cycle and the difference in the internal and external temperature of the room and radiant intensity. Subsequently, I obtained the relevant regression coefficients according to the theoretic data of solar house that we have built. On the other hand, we have collected the experimental data of 4 consecutive days about my question of discussion task. I calculated the theoretic heat cycle every hour in terms of the experimental data and above regression coefficients. Compared with the experimental heat cycle, we found that both results were very similar. The results showed that I have established some accurate dynamic mathematical models and the accurate regression equation .I can draw a conclusion that these regression coefficients are credible. In the future, the designer can calculate and design thermal parameters regarding this kind of passive solar house fleetly and correctly according to my regression equation and these regression coefficients. they can save time and enhance the working efficiency.
