Portable energy storage box material

What is the cooling performance of a PCM-based cold thermal energy storage box?

Melting points of the PCMs varies the box cooling time from 2.1 to 9.6 h. The vacuum insulated panel can prolong the cooling time of the box to 46.5 h. Cooling performance of a portable box integrating with phase change material (PCM)-based cold thermal energy storage (TES) modules was studied and reported in this paper.

What are the dimensions of a portable box?

Physical model Fig. 1 shows the portable box studied on this work, which is one of the typical boxes in practical applications. The outer dimensions of the portable box are 430 mm (Length) × 285 mm (Width) × 345 mm (Height), and the internal dimensions are 355 mm (L) × 215 mm (W) × 265 mm (H).

What is discharging depth in thermal energy storage based cold box?

The discharging depth is defined as the ratio of energy released for cooling the interior to the energy stored in the device, can be used as an indicator for the optimization of the thermal energy storage based cold box. In this work, the liquid fraction of the PCMs inside the cold plates is used to represent the discharging depth.

Which insulating material is used to insulate a box?

The distribution of 20 % PCM at the top and 80 % PCM on the inner wall in the box was applied, and the PU was chosen as the insulating material of the box. Fig. 10. Comparisons of the central temperature of the box with the PCMs having different melting points.

Can thermal energy storage with phase change materials be used for cold storage?

We propose the use of cold thermal energy storage method with phase change materials for cold storage to address these issues. Thermal energy storage (TES) with phase change materials (PCMs) has several advantages including large energy density [18, 19] and constant temperature during the phase transition [20, 21].

What are box walls made of?

The box walls are made of insulation materials, and the PCM plates/modules are in close contact with the box internal surfaces. Fig. 1 a and Fig. 1 b illustrate respectively the physical geometry of the box and meshing grids for the modelling.
