Advantages and disadvantages of PCMs [7].

Classification	Advantage	Disadvantage
Organic PCMs	(1) Availability in a large temperature range; (2) High heat of fusion; (3) No supercooling; (4) Chemically stable and recyclable; (5) Good compatibility with other materials	(1) Low thermal conductivity; (2) Relative large volume change; (3) Flammability
Inorganic PCMs	(1) High heat of fusion; (2) High thermal conductivity; (3) Low volume change; (4) Availability in low cost	(1) Supercooling; (2) Corrosion
Eutectics	(1) Sharp melting temperature; (2) High volumetric thermal storage density	Lack of currently available test data of thermophysical properties
