Energy Saving Simulation of Phase Change Materials in the Enclosure Structure of Archives Warehouse in Different Climatic Regions

Different climates in different regions have an important influence on the latent heat performance of PCMs, especially outdoor temperature and solar irradiance. This paper describes the addition of PCMs outside the archives warehouse in Guangzhou and Lhasa, and the temperature change and energy conservation of the exterior enclosure of the warehouse in summer and winter. In typical summer days in Guangzhou, PCMs with a phase change temperature of 30°C should be added to reduce the indoor cooling load by 23.91%. In typical winter days in Lhasa, PCMs with a phase change temperature of 8°C should be added, which can reduce the indoor heat load by 17.28%
