Abstract

Phase change materials (PCM’s) are substances that absorb or discharge heat called 'latent' heat as they experience a change in their physical state. For applications such as passively cooled buildings, waste thermal storage, load shifting, textiles, for food, cooling for electronics, and medicine transport containers, human comfort, and energy conservation, among others, various materials have been investigated for their potential use as PCM. Material choice for a given application can be a difficult assignment. Almost research scholars use PCM specifically relying upon their experience or accessibility of the material. The selection of materials is an incessant loop aimed at finding best material for a specific application and fulfilling an arrangement of forced necessities. In order to enhance the nature of choice, an efficient assessment method is necessary. It is possible to treat the issue of selecting material for an engineering application as multi-criteria decision-making technique. By considering technical specifications of the materials, in this exploration paper the GRA, COPRAS and MOORA technique was utilized for the choosing of PCM.
