Abstract
Abstract
This study aims to examine the melting processes of encapsulated PCM in a cylindrical-shaped capsule, made of stainless steel. It has a diameter of 60 mm and a height of 20 mm. The chosen PCM is the paraffin RT35HC, which has a melting point around 35 ºC. Experiments are conducted in a water-filled thermal bath, placing the capsule vertically and heating the water using a thermostat. Temperature field analysis of the PCM is performed using thermocouples, and simultaneously, the inside of the encapsulated material is observed through a transparent wall. It has been proven that the sensors are capable of detecting the gradual evolution of the liquid phase of the PCM and its accumulation at the top of the capsule due to its lower density.
