Research On The Joint Application Of Solar House And Phase-changing Heat-collecting Wall With Ventilation

By testing mixing paraffin thermal parameters, we get the best ratio ofcomposite phase change paraffin. Hot melt making high polyethylene (HDPE) andparaffin mixture, get stereotyped composite phase change paraffin. On the base ofsearching of composite phase change heat transfer performance of the paraffin blockwall, draw pictures of wall composite phase change temperature curve and compositephase change temperature of the wall layers spread rate curve, and use this as basis toanalysis the insulation properties of composite phase change paraffin block wall.Use the system of solar radiation table collection, collect local full year solarradiation. By collecting data, we can get Changchun full year, each month of solarradiation and each period of solar radiation, to sum up the regular pattern of solarradiation intensity distribution of Changchun, research on the influence of thesunshine to the passive solar building.Design and study Combined Application of the passive solar building andphase transition collector wall.Research on the question of heat transfer of phasechange wall. Research on the inside changing temperature of passive solar buildingwith composite phase change paraffin. Study the heat transfer characteristics ofcomposite phase change thermal storage wall with heat wave action.Use the measured data to analyze the wall stress, and use the finite elementsoftware to simulate heated wall. The difficulty of researching on exterior wall stressis to establish the temperature field with realistic conditions, and make sure that whereis the effect region of the temperature stress. In this paper, we use ANSYS to study onthe thermocouple of the insulation system, calculate the digital size and deformationsize of the stress. Through the theoretical analysis and processing data, we can get thediscipline from studying and analyzing the change of temperature stress, also we canuse it to guide the actual project.
