AB - The author proposes a phase change heat storage component combined with the  light wall interior to improve the heat storage performance. Numerical  modelling of the composite wall was performed using the finite element  program COMSOL connected to Multiphysics simulation, and its accuracy was  verified. In order to optimize the use of phase change data and the benefit  of phase change temperature, the phase change of the heating device was  carried out, and the difference in the development efficiency of the thermal  storage performance of the two types of light walls was obtained from the  ribs in the thermal phase phase exchanger compared. The results show that  the long and thin fins adjust the temperature and flow field changes of the  paraffin to the corresponding fin gap and improve the heat transfer rate,  44.8 and 26.3, respectively, the aerated concrete combined wall heat storage  and heat release time, added short ribs known need, and the connected wall  delay time is not affected by external heat. The mature thermal insulation  and thermal insulation time of the polystyrene board composite wall were  shortened by 20.8 and 52.9, respectively. Ribs are able to improve heating  efficiency and retain heat in the broken walls of polystyrene panels. The  author's research can provide a rationale for the design and use of phase  change thermal storage.
