companies. The encapsulated PCMs such as Microtek-BASF, Cristopia, Climator and Rubitherm are commercializing encapsulated PCMs (EPCMs) with the name of DS5001X, RT 5, and RT 25 etc. within temperature range of below ambient to above 100°C [25–29]. The encapsulated PCM is a tiny particle which contains core as PCMs and Shells are the polymers and inorganic substances (**Figure 5)**.
