Table 1
Comparison between organic PCMs and salt hydrate PCMs
| Comparison | Organic PCMs | Salt hydrate PCMs |
| Advantages | Non-corrosive | High thermal conductivity |
| Low supercooling degree | High volumetric latent heat storage | |
| Good chemical and thermal stability | Low price | |
| Disadvantages | Low volumetric latent heat storage capacity | High supercooling degree |
| Low thermal conductivity | Prone to phase separation | |
| High flammability and toxic combustion products | Corrosion to metals | |
