Metastable supercooled liquid phase change material (MSLPCM) is prepared by homogeneous mixing of sodium acetate trihydrate (SAT), water and ethylene glycol (EG) in 92:5:3 weight fractions, respectively. A stainless steel (SS-306) triggering disk of size 20 mm (L) × 18 mm (W) × 0.2 mm (T) is fabricated by engraving grooves on SS disk for initiating nucleation in heat pack and release of heat at the time of requirement. The PCM heat pack containing 300 g PCM and a triggering disk is fabricated using high frequency PVC sealing machine. Thermal performance of identical PCM heat pack and water pack (300 g water) is carried out inside temperature history measuring setup at 0 °C ambient temperature. The temperature of PCM heat pack and water heat pack reduces from 70 to 30 °C in 210 and 48 min, respectively at 0 °C ambient temperature. The heating time of PCM heat pack is ~4.4 times more compared to water heat packs. © 2020, Springer Nature Singapore Pte Ltd.
