Case Study

Evaluation of the Potential of Dodecane-Tridecane System as Phase Change Material for Cold Storage

Gunasekara, Saman Nimali, et al. International Journal of Refrigeration, 2017, 82, 130-140.

Combining thermal storage with phase change materials (PCMs) in refrigeration and air conditioning processes can improve energy performance. In this work, the experimental phase diagram of the dodecane-tridecane (C12H26-C13H28 ) alkane system was evaluated to find PCMs for refrigeration applications.
Key Findings
· The T-History evaluations suggest the existence of a minimum-melting solid solution in the C12H26-C13H28 system, followed by polymorphic transitions. This minimum-melting composition is identified within the range of 15-20 mol% C13H28, with the closest value being 17.7 mol% C13.
· The 17.7 mol% C13 composition has melting and freezing points between -16 °C to -12 °C and -17 °C to -15 °C, respectively, with enthalpies of 185 kJ kg-1 and 165 kJ kg-1, exhibiting no supercooling and only slight hysteresis (1-3 °C). Therefore, it holds promise as a potential phase change material (PCM) for freezing refrigeration applications.

Preparation and Research of Silica-Coated n-Tridecane Phase Change Microcapsules

Liu, Sikai, et al. Energy and Buildings, 2025, 334, 115490.

Encapsulated phase change materials (ePCM) can adjust the volume and fluidity of phase change materials, as well as significantly improve the thermal conductivity of phase change materials. This work aims to design nano-encapsulated phase change materials (n-tridecane@silica NePCM) with excellent thermal conductivity and cold storage capacity and nano-scale particle size, which can be applied to the surfaces of refrigerated facilities, refrigerated trucks, incubators, etc. below 0 ℃.
· Preparation of n-tridecane@silica NePCM
Low-temperature nano-encapsulated phase change microcapsules with varying core-shell ratios were synthesized through in-situ polymerization. The nanocapsule shell is made of silica derived from the hydrolysis of tetraethyl orthosilicate (TEOS), while n-tridecane serves as the core material.
· Performance of n-tridecane@silica NePCM
The SEM images reveal that the microcapsules are spherical and possess a nanoparticle size. Differential scanning calorimetry (DSC) tests indicate that the phase change nano-capsules, using n-tridecane as the phase change material, exhibit two phase change peaks. At a core-shell ratio of 1:1, the latent heat of melting and freezing reaches 124.46 J·g-1, with an encapsulation efficiency of 69.79%. Thermogravimetric analysis (TGA) results affirm that silica encapsulation enhances the stability of the phase change materials. After 500 phase change cycles, the latent heat of the nano-capsules shows minimal change, indicating strong thermal reliability.
