“…In the case of internal melt ice-on-coil tanks, Zhu [14] validated a model with experimental data from Li [16,18] who showed that, although the cooling power decreases progressively, at the end of the discharge process the cooling power can increase in a short time period due to the ice floating. Nevertheless, the internal melt ice-on-coil tanks which have been studied are generally of small capacities such as with single horizontal tubes [18,19] [20,21] or small tanks [22].…”

In this paper, the discharge of an experimental ice-storage tank is analyzed. The storage tank is an internal melt-ice-on-coil system. The discharge process has been studied for different mass flow rates and supply temperatures in the range from 10ºC to 15ºC. The results indicate that once the ice breaks and floats towards the top of the tank, convection in the ice/water mixture is enhanced and the heat transfer fluid in the top coils becomes colder than in the bottom coils. Thus, an increase of the cooling power is generally observed around the ice-breaking point. Two correlations have been developed to reproduce the effect of the mass flow rate and supply temperature on the discharge duration and the mean cooling power. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 Keywords: Thermal storage, experimental installation, PCM, ice melting, ice floating *Manuscript-UnmarkedCopy Click here to view linked References

“…water from 0.033 kg/min to 0.167 kg/min, energy efficiency increases from 63.88% to 77.41% [20] During the solidification process, the inlet temperature of HTF is more significant than the flow rate. As the HTF inlet temperature is increased, the temperature difference between the HTF and the PCM unit increases to lead the larger heat transfer rate [21] Increasing mass flow rate increases the heat transfer rate and the molten volume fraction. Increasing inlet temperature rate increases the heat transfer rate and the molten volume fraction.…”

Summary Because of the unstable and intermittent nature of solar energy availability, a thermal energy storage system is required to integrate with the collectors to store thermal energy and retrieve it whenever it is required. Thermal energy storage not only eliminates the discrepancy between energy supply and demand but also increases the performance and reliability of energy systems and plays a crucial role in energy conservation. Under this paper, different thermal energy storage methods, heat transfer enhancement techniques, storage materials, heat transfer fluids, and geometrical configurations are discussed. A comparative assessment of various thermal energy storage methods is also presented. Sensible heat storage involves storing thermal energy within the storage medium by increasing temperature without undergoing any phase transformation, whereas latent heat storage involves storing thermal energy within the material during the transition phase. Combined thermal energy storage is the novel approach to store thermal energy by combining both sensible and latent storage. Based on the literature review, it was found that most of the researchers carried out their work on sensible and latent storage systems with the different storage media and heat transfer fluids. Limited work on a combined sensible‐latent heat thermal energy storage system with different storage materials and heat transfer fluids was carried out so far. Further, combined sensible and latent heat storage systems are reported to have a promising approach, as it reduces the cost and increases the energy storage with a stabilized outflow of temperature from the system. The studies discussed and presented in this paper may be helpful to carry out further research in this area.
