A kind of composite phase change refrigerant for the regenerator is developed
which is mixed with diethylene glycol on the basis of aqueous solution with higher heat of substitution. The optimal ratio of diglycol aqueous solution is obtained by low temperature eutectic material calculation: 10% diethylene glycol
90% water. The phase change storage material with different mass fractions based on the calculation results is tested by differential scanning calorimetry(DSC). The experimental result and the calculation result are identical
indicating that the refrigerant has ideal latent heat and temperature of phase change and can be used in storage tank of LAES. Finally
the ANSYS is used to simulate the application of the new phase change storage refrigerant in the regenerator of LAES system and its excellent cold storage performance is verified.
