“…Especially in hot climates, the annual peak in the electricity grids occurs in the hottest day of the summer. In such climates, if the cooling load is shifted to night-time hours, cold storage systems can help reduce the energy costs [1][2][3][4] and reduce the overall CO 2 emissions as the peak power loads are generally covered by fossil fuel thermal power plants. Although the total energy consumption in cold storage installations is generally higher than conventional systems due to the lower evaporation temperatures of the chiller [5][6] and to the additional heat transfer losses, the energy costs can be lowered particularly when rate structures with strong load-shifting incentives are applied [4].…”

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

“…It is usually stored in specially insulated water tank for daily storage (e.g., [18]) or underground for seasonable storage (e.g., [19]), in connection with the HVAC system of buildings. Ice, as the solid state of water, is also used as storage media, to be stored in special ice storage tanks for daily operation (e.g., [20,21]). In some cases, ice remains solid during charging/or discharging when it exchanges sensible heat with HTFs (usually air) whereas in other cases phase change may occur to produce chilled water [22], indicating that both sensible and latent heat are involved.…”

This chapter presents a state-of-the-art review on the available thermal energy storage (TES) technologies by sensible heat for building applications. After a brief introduction, the basic principles and the required features for desired sensible heat storage are summarized. Then, material candidates and recent advances on sensible heat or cold storage adapted for building application are discussed, each with its own characteristics, advantages, and limitations. A large section of the chapter is devoted to the sensible TES technologies for buildings, both for short-term (daily) and for long-term (seasonal) storage. Each technology is described in detail including different aspects: basic principle, development status, performance and costs, potential and barriers, today's R&D activity focus, etc. Comparisons on the advantages and limitations between different TES technologies are also made. Finally, conclusions and future directions are summarized.

“…Some of the research work done to study the effect of partial load operating conditions was focused on numerically studying and optimizing the size of sensible cold storage systems for cooling purposes by comparing full storage and partial storage strategies to conventional systems [2][3][4][5][6][7]. According to Dincer [8], the full storage strategy shifts the entire peak cooling load to off-peak hours, while the partial load strategy is used to either level the load or limit the demand, since the cooling load is partially met by the cooling source and partially met by the storage system.…”

Sebzali et al [2] studied the effects of using partial and full loads strategies on the TES and chiller size, the reduction of electrical peak demand and the reduction of the energy consumption of a chiller for a clinic building in Kuwait. They found that full storage operation allows larger electrical peak reduction and chiller and storage capacities, while it presents the higher energy consumption.…”
