3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Phase change materialssusedinbuildings Products, components, energy systems, etc. applied to buildings can change the phase of matter with temperature, and provide latent heat storage and release. substance. 3.2 Thermal reliability The phase change material performs the ability to store and release heat under specified conditions and for a specified period of time. 3.3 Phase change temperature phasechangetemperature In a specific environment, the phase change material absorbs (releases) heat from a solid phase to a liquid phase (from a liquid phase to a solid phase), and the corresponding temperature is called It is the phase change temperature. The phase transition temperature is further divided into a melting temperature and a solidification temperature. 3.4 Phase change latent heat phasechangelatentheat Under certain temperature and pressure conditions, the unit mass of phase change material is absorbed from the solid phase to the liquid phase (from liquid phase to solid phase) (release) the heat. The latent heat of phase change is further divided into latent heat of fusion and latent heat of solidification. 3.5 Phase change temperature variation variationofphasechangetemperature The change value of the phase transition temperature of the phase change material for building after multiple melting and solidification processes. 3.6 Phase change latent heat change rate variationratioofphasechangelatentheat The percentage change of the latent heat value of the phase change after the phase change material of the building undergoes multiple melting and solidification processes. ......
