The Influence of Phase Change Building Envelope Materials on Indoor Heating Design
Phase change materials for building envelope structures effectively improve indoor insulation performance,and studying their optimal preparation method and its impact on heating can provide theoretical basis for engineering personnel.The proportion of building maintenance structural materials,carrier adsorption process,and packaging method were optimized,and the impact of material temperature regulation and insulation performance on indoor heating design was analyzed.The results showed that the mass ratio of lauric acid,stearic acid,and palmitic acid was 65.9:10.5:23.6.With the increase of adsorption temperature and time,the tolerance of expandable graphite increases first and then decreases.The optimal adsorption temperature is 55℃,and the optimal adsorption time is 50min.It is recommended that the lotion cement powder adhesive packaging of stone like paint be used.Compared to ordinary cement mortar,the maximum central temperature of phase change cement mortar significantly decreases after being heated,and the temperature inside the wall of phase change cement mortar is significantly lower.The time required to reach the maximum temperature is extended,and the good temperature regulation ability and insulation performance effectively improve the heat storage and transfer capacity of the building enclosure structure.The supplementary heating capacity of the heating system is reduced.
