4. Conclusions
- After DSC test, it was found that when the mass ratio of calcium chloride hexahydrate to glycerol was 85:15, the phase change temperature of the composite phase change material was 11.8 °C and the enthalpy of phase change was 112.86 J/g, which was suitable for the field of air-conditioning.
- FTIR confirmed that the material was successfully developed and proved that the two reagents only acted physically, without chemical reaction.
- The material still showed good thermal stability after 50 thermal cycles. The subcooling of the new CPCM only increased by 0.28 °C after 50 cycles and the enthalpy of CPCM has almost no change.
