3. General description of immersion-cooling method. The advanced technology of immersion cooling method involves the reduction of heat component using a dielectric liquid [61] which absorbs the heat source by convection and release to the environment through either a single-phase or two-phase system [6].
Energy storage systems can alleviate this problem by storing electricity during periods of low demand and releasing it when demand is at its peak. Liquid air …

To reduce the energy consumption, free cooling strategies are used more and more, but so far there has been little research about the potential of thermal energy storage (TES) solutions to match energy demand and energy availability.
Abstract. Latent heat thermal energy storage (LHTES) integrated active free cooling stores night time cold and serves as heat sink for cooling when demand rises. Passive buildings, albeit their advantages in limiting heat loss during winter time, are often paired with excessive internal overheating in summer, as shown in the first part of this ...

The proposed CES-ORC-DC-LNG system can recover LNG cold energy in different temperature ranges with an appropriate process …
Such a configuration limits the energy storage density as well as makes the system more energy-intensive due to repeated circulation of dilute solution. Further, the evaluation only considers the absorbent side, but the operating conditions of air also could affect the performance of the system significantly as can be noted in the conventional …

Introduction of an energy storage system to the CSP plants can be a viable solution of this issue [6]. The energy can be stored in the sensible, latent and chemical form. However, owing to the high density and high temperature energy storage in CSP plants with lesser volume, latent heat storage systems attract more attention.
Aquifer thermal energy storage systems in combination with heat pumps are deeply studied [84], [85]. The analysis proposed in [148] considers both heating and cooling demand with a COP of 17.2 in cooling mode and a COP of 5 in heating mode.
