Abstract: To study and analyze the performance characteristics and the effectiveness of the system under practical application scenarios, the present work compares the performance of solar energy phase change material storage wall systems suitable for buildings in hot summer and cold winter regions under different summer working conditions. The experimental facility was installed on light-weight insulation wall and ordinary wall; ventilation conditions of shutting/opening doors and windows, respectively, were set. The experimental facility showed different thermal characteristics when it was installed on insulation wall and on solid wall whether it was vented or not; under vented working condition, the temperature of the external surface of the south-facing wall which attached to the solid wall experimental system was lower, demonstrating that under practical building scenarios the present technology could better reveal its capability of avoiding the overheating issue of the solar heating wall in summer.
