Research report on microcrystalline ice energy storage technology

What are the advantages of ice-crystal type ice storage air-conditioning system?

Ice-crystal type ice-storage air-conditioning system not only has the advantages of stable ice making and ice melting process and large energy-storage density, but also can save the storage space of the system and have a strong adaptability.It has good energy saving effect and economic benefit.

What is thermodynamic performance of ice thermal energy storage systems?

"Thermodynamic Performance of Ice Thermal Energy Storage Systems ." ASME. . December 2000; 122 (4): 205–211. The thermodynamic performance of an encapsulated ice thermal energy storage (ITES) system for cooling capacity is assessed using exergy and energy analyses. A full cycle, with charging, storing, and discharging stages, is considered.

What are the characteristics of ice storage system in ISS?

All these mentioned specific characteristics of water affect solidification of water (charging) as well as melting of ice (discharging) inside ISS. Ice storage system stores cold thermal energy for later use (e.g., district cooling). This system does not require maintenance and operate for long years .

Why is ice storage system a high thermal energy density?

Ice storage system (ISS) offers a high thermal energy density due to the large amount of latent heat compared with sensible heat of chilled water. In addition, cold thermal energy can be stored and delivered at nearly constant temperature .

Are ice storage systems reliable?

Therefore, for more general reliable predictions, modeling of ice storage systems should consider more reliable models considering the effect of natural convection, maximum density, and ice floating. A literature review is presented on heat transfer enhancement of ice storage systems.

What are the unsolved technical problems in ice thermal energy storage?

These are many unsolved technical problems in ice thermal energy storage, including low thermal conductivity of water, thermal stratification phenomenon and poor economy, which limit the further development of this technology.
