Learn MoreIn these systems, colder water remains at the bottom, and warmer, lower-density water remains at the top. During times of peak cooling demand, the cooler water flows out the bottom and is integrated into the cooling system, leaving warm water in the tank. During of-peak hours, the warm water exits the tank at the top and runs to the chiller.
Within the power plant, the following equipments need cooling water: air-water heat exchangers (related to generators and HVAC system); oil-water heat exchangers (related to bearings, speed governors and transformers); coolers of the turbines seals.
There are two basic Thermal Energy Storage (TES) Strategies, latent heat systems and sensible heat systems. Stratification is used within the tank as a strategy for thermal layering of the stored water. Colder water is denser and will settle toward the bottom of the tank, while the warmer water will naturally seek to rise to the top.
Thermal Energy Storage in district heating and cooling systems serves as a reserve of thermal energy, which can be used to supply heat or cooling load in times of peak demand or in times of high electricity prices – when heat is produced through electric heaters or heat pumps.
Wenpeng Hong, in Journal of Building Engineering, 2022 ITS uses the latent heat (resulting from phase transitions) of water to obtain high densities of cooling energy. As the cold storage media, water has many advantages, including high latent heat of fusion (334 kJ/kg), low cost, environment-friendly, non-toxic .
The basic principle is the same in all TES applications. Energy is supplied to a storage system for removal and use at a later time. What mainly varies is the scale of the storage and the storage method used. The process of storing thermal energy can be described in three steps, referred to as a cycle.
