Underground Storage of Latent Heat: Theory and Experiments

2018
Thermal heat storage in the subsurface can be in the form of latent heat. In this way heat can be stored in the form of ice, where heat is stored when ice melts, and heat is extracted by ice formation. We investigate the use of a borehole device for heat exchange with the subsurface.

Thermal performance evaluation of non-uniform fin array in a finned double-pipe latent heat storage system

, 2020
This paper aims to evaluate the effects of fin arrangement in a vertical finned double-pipe latent heat storage system based on the locations, thickness and diameter of the fins in melting and solidification mechanisms.

High‐Efficiency Thermal‐Shock Resistance Enabled by Radiative Cooling and Latent Heat Storage

Advances in Materials
Radiative cooling technology is well known for its subambient temperature cooling performance under sunlight radiation. However, the intrinsic maximum cooling power of radiative cooling limits the performance when the objects meet the thermal shock. Here,

Recyclable Solid–Solid Phase Change Materials with Superior Latent Heat via Reversible Anhydride‐Alcohol Crosslinking for Efficient Thermal Storage

Advances in Materials
Solid–solid phase change materials (SSPCMs) with crosslinked polymer structures have received sustained interest due to their remarkable shape stability, enabling their application independently without the need for encapsulation or supporting materials.

Charging performance optimization of a latent heat storage unit with fractal tree-like fins

, 2020
The significant deficiency of the latent heat storage (LHS) technology is the poor heat charging and discharging efficiency. Here invokes a fractal tree-like fin to strengthen the melting property of LHS units inspired by bionics in nature.

Melting performance enhancement of a latent heat storage unit using gradient fins

, 2020
Latent heat storage (LHS) is critical for the large-scale utilization of sustainable energy. The present paper designs the gradient fins (i.e., fins with gradient thickness and gradient central-angle) to enhance the melting performance of a LHS unit.

Heat transfer in a latent heat-storage system

Energy, 1989
The heat-recovery rate has been determined in a latent-heat storage unit using Na2HPO4 · 12H2O as a heat-storage medium. The effects of the liquid flow rate and inlet temperature of the heat-transfer fluid on the heat-recovery rate have been determined. The heat-recovery rate decreases sharply at the beginning of the heat-recovery stage.

Performance evaluation of melting/solidification mechanism in a variable wave-length wavy channel double-tube latent heat storage system

, 2020
Thermal energy storage and recovery in a double-pipe latent heat storage (LHS) system with variable wave-length wavy channels were examined. The presence of wavy channels with variable wave-length makes it possible for the desired aggregation of the ...
