Abstract:
At present, energy storage systems and cooling systems using phase change materials (PCMs) as energy storage are popular to use in industrial, greenhouse include build the house. But PCMs must be selected with properties to proper application. Therefore, in this thesis, a 1D heat transfer model of PCMs with longitudinal fins has been studied to determine the heat transfer performance of PCMs. It uses the principles of thermodynamics and the Stefans transient 1D heat transfer equation to crate an ordinary differential equation. In addition, analytical methods are used to find answers. Leads to programming in Microsoft excel. This thesis has been studied 5 PCMs are paraffin, salt hydrate, erythritol, lauric acid and palmitic acid. The results are salt hydrate were fastest solidified in 5 PCMs. In addition, influence of parameters to solidification, temperature distribution including the heat transfer are studied.
