Experimental investigation of a spiral tube embedded latent thermal energy storage tank using paraffin as PCM

Latent thermal energy storage (LTES) is widely used in excess energy reservation. The performance of a LTES unit is critical for its application. In this study, the spiral tube embedded LTES tank is investigated experimentally, with a composite of paraffin as the phase change material (PCM). Tempera...
