Using phase change material in under floor heating

In the last decade, studying of thermal energy storage systems using phase change material (PCM) in the field of building has been increasingly developed. Indeed, it decreases the energy consumption used for indoor heating system while maintaining maximum thermal comfort for the occupants. This paper presents a study on application of white petroleum jelly, which is used as a phase change material, with an electrical under floor heating system. To proceed, a prototype of a well-insulated house is constructed. An experimental study was carried out in a relatively cold weather to investigate the thermal behavior of using phase change material. Results show that at an average ambient temperature QUOTE of 14℃ the electrical consumption was shifted by an average of 6 hours due to the latent heat stored in PCM.
