Abstract. The energy demand for cooling and air conditioning systems is increasing worldwide, especially in regions with high solar radiation intensity. One of the reasons for this is the increase of comfort demands worldwide. The most cooling and air conditioning systems are the conventional electrically driven one type such as
During energy storage process, the sorption material (zeolite) is charged by air using the thermal energy from district heating system to around 130 C at night time. During the day time, the heat stored in the sorption material is discharged to building based on the thermal energy demand.
Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to
Low efficiency of cooling systems leads to a cooling cost at about 40% of the total energy consumption of a data center. Due to specific operation conditions, high security and high cooling load is required in data center. To achieve energy saving, cost saving and high security, novel cooling systems integrated with thermal energy storage
There are four thermal management solutions for global energy storage systems: air cooling, liquid cooling, heat pipe cooling, and phase change cooling. At present, only air cooling and liquid cooling have entered large-scale applications, and heat pipe cooling and phase change cooling are still in the laboratory stage.

Considering China''s the large population, grain production and storage particularly play a vital role in its the national security. According to the white paper of "Food Security in China" published by the State Council of China [3], China''s annual grain production has remained above 650 × 10 6 t since 2015, and the grain storage capacity
In addition, the multiple mechanical technologies used to cool and circulate air generate heat themselves and consume increasing amounts of energy just to operate. Liquid cooling was once thought of as being all about full ''bathtub'' type immersion – and many experienced data centre professionals have been wary of any sort of liquid
The passive cold energy storage technology shows diverse applications, including air condition for building cooling, cold chain logistics in transport, vaccine cryopreservation in medicine. Both sensible heat storage material and PCM can be used in passive cold storage but PCM is attracted more attention in recent years.
As renewable energy production is intermittent, its application creates uncertainty in the level of supply. As a result, integrating an energy storage system (ESS) into renewable energy systems could
Latent heat storage (LHS) leverages phase changes in materials like paraffins and salts for energy storage, used in heating, cooling, and power generation. It relies on the absorption and release of heat during phase change, the efficiency of which is determined by factors like storage material and temperature [ 102 ].
Liquid air energy storage (LAES) represents one of the main alternatives to large-scale electrical energy storage solutions from medium to long-term period such as compressed air and pumped hydro energy storage.
In a study by Javani et al.

Third, new and emerging energy-saving cooling technologies, such as thermal energy storage based cooling technologies, were poorly reviewed and often lack of comparison with existing technologies. These make it difficult to objectively judge the actual advantages and disadvantages of each of these cooling technologies for DCs
3 · 3. Thermal energy storage. Thermal energy storage is used particularly in buildings and industrial processes. It involves storing excess energy – typically surplus energy from renewable sources, or waste heat – to be used later for heating, cooling or power generation. Liquids – such as water – or solid material - such as sand or rocks
Proper cooling technology can reduce the negative influence of temperature on battery pack, effectively improve power battery efficiency, improve the safety in use, reduce the aging rate, and extend its service life.

Liquid air energy storage (LAES) uses air as both the storage medium and working fluid, and it falls into the broad category of thermo-mechanical energy storage technologies. The LAES technology offers several advantages including high energy
Thermal energy can be reserved in three ways based on the underlying physical principles of the storage technique: sensible and/or latent storage, thermochemical energy storage (TCM). This classification is shown in Fig. 2 and recommended differentiate between materials for thermochemical, latent heat and sensible heat storage.
Furthermore, as underlined in Ref.

When direct air free cooling is implemented into the refrigeration system, the increase of the air inlet room temperature does have an important effect on the cooling energy reduction. Even though the use of direct air free cooling requires electricity consumption, the chiller is not running for many hours and therefore the overall energy
