Abstract

Indonesia is one of tropical country with a relatively warm temperature. Therefore Thermal Energy Storage(TES) need to be installed at building to maintain its comfort room temperature. This research studies the properties of phase change material with coconut oil and expanded graphite mixture for building energy storage applications. As an organic PCM, coconut oil has a low thermal conductivity, therefore expanded graphite are used as the supporting material to enhance thermal performance of the PCM. PCMs was prepared by sonicating expanded graphite into coconut oil with the mass fraction of 0.1 until 0.5 wt%. Thermal conductivity experiment was conducted with Huber thermostatic bath and KD 2 Pro analyzer. The morphology was generated with SEM experiment. The chemical structure of the mixture was generated by FTIR experiment. Particle size of the expanded graphite was generated with PSA experiment. The result in this study showed that expanded graphite and coconut oil mixture PCM show an continues improvement in thermal conductivity. with the highest increase of 19% at mass fraction of 0.5 wt%. also with sociation mixing methods and FTIR result shows that expanded graphite and coconut oil has no change in chemical structure.
