【 摘 要 】

The experimental study is performed to investigate the solidification behaviour of water-based PCM in different capsule materials filled with 90% of its volume. The experiments are conducted with two stainless steel material and high-density polyethylene (HDPE) spherical capsules are maintained at different surrounding temperatures of -9°C and -12°C filled with 90% of PCM in its total fill volume. From the experimental results observed that the capsule material gives considerable effect on subcooling at lower temperature driving potential. Considering the experimental study which is concluded that solidification process time of encapsulated PCM of stainless steel material requires less time comparing to HDPE material.
