Super-Cooling Suppression of Microencapsulated PCM

Microencapsulated Phase change material can absorb and release large amounts of latent heat over a defined temperature range as its physical state changes. The microencapsulated PCM has high energy density and isothermal behavior during charging and discharging and can avoid the contradiction of the energy supply and demand unbalance in time and space. Meanwhile, the shell can separate the phase change material from the outside environment in order to protect the core material. But the super-cooling problem is a main barrier for microencapsulated PCM application. So this paper talks about how to dealing with super-cooling based on related literatures and gives an overview about the methodology in this area.
