Use of one-way cold-release energy storage box

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].

How does cold energy storage work?

Cold energy storage methods store the cold energy in PCM by electrical energy which releases energy in the daytime and charges in the night time when the electricity is cheaper than in the daytime, resulting in an overall lower cost , .

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 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.

Is cold thermal energy storage a good option?

Policies and ethics Cold thermal energy storage (TES) has been an active research area over the past few decades for it can be a good option for mitigating the effects of intermittent renewable resources on the networks, and providing flexibility and ancillary services for managing...

What is the structure of a cold storage box?

The structure of the box is cuboid. To avoid products chilling injury from the cold storage plate, the space can be divided into a fresh-keeping area and a cold-storage area with an adjustment plate. The performance of the cold energy release is an essential evaluating indicator for the box, which is affected by many factors.
