▎ 摘　　要

NOVELTY - Preparing phase change heat storage floor comprises (1) mixing and stirring the organic/inorganic heat storage material and porous carrier to prepare a composite phase change material; (2) physically mixing the cement powder and composite phase change material powder, adding water, stirring with industrial mixer, after completely adding water, continuously stirring until the mixture is fully mixed to obtain phase-change cement mortar that is evenly mixed and has a viscous texture; and (3) pouring evenly mixed and viscous phase-change cement mortar into the model floor structure, vibrating, trimming and maintaining to obtain a phase-change heat storage floor. USE - The method is useful for preparing phase change heat storage floor. ADVANTAGE - The phase change heat storage floor: can achieves the effect of building energy saving and is convenient for large-scale use. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for radiant heating use of phase change heat storage floor, comprising applying the phase change heat storage floor to radiant heating, the ground paving structure from top to bottom is: ceramic tile surface layer, phase change heat storage floor and heating system, the heating system is one of hot water supply pipe, electric heating film and heating cable.
