Because of the limited space inside the cabinet, expanding the heat dissipation area is the optimization direction of the water-cooled plate with a balanced performance between pressure drop, maximum temperature, and temperature uniformity.
This implies that thermal energy storage (TES) plays a broad and important role in efficient and sustainable energy use. According to the storage mechanism, TES is divided into three types: sensible heat, latent heat, and thermochemical heat storage.
Such a system integrated with an absorption chiller can efficiently serve for both heating and cooling, and even can be a cost-competitive energy storage attempt to power generation in spite of low roundtrip efficiency. The energy density of thermophysical heat storage may exceed that of thermochemical heat storage.
A crux is the time-scale mismatch between energy supply and demand, which limits high-efficiency and large-scale utilization of renewable energy sources such as solar energy and wind energy, industrial waste heat, and off-peak electricity. Energy storage is to serve this kind of scenario and decouple supply and demand in energy systems.
Energy density represents the development potential of a TES technology, usually as the primary research orientation. This is why the latent heat storage is widely focused and the thermochemical heat storage is emerging. Moreover, it also affects its applicability and investment cost.
Results show that the power usage effectiveness is reduced from 1.317 for the original data center to 0.981 for the proposed system because of the combined energy savings of uninterruptible power supply replacement with ESB and waste heat recovery for cooling and power generation.

6 Note that thermal energy is not necessarily just kinetic; it may have a configurational component to it as well. For example, imagine a collection of vibrating diatomic molecules. You may think of each one as two atoms connected by a spring. The length of the "spring" at rest determines the molecule''s nominal chemical energy; thermal vibrations cause this length to change, resulting …
