Thermal performance of latent heat storage: Phase change material melting in horizontal tube applied to lightweight building envelopes

Experimental investigations of the thermophysical properties of the considered composite (gypsum/copper tubes) have shown that the material combines a high heat storage potential and an improved heat transfer at the same time. Besides, the results showed that the shape-stabilized phase change material prevents the leakage of the molten paraffin during phase transition and proved a good thermal stability.
