As mentioned in Section 2.5, the effectiveness of heat exchanger is usually regarded as an ideal value in previous studies, that is, it is set to be equal in energy storage and energy release phases and is not affected by other parameters.
Thermal energy storage (TES) systems can store heat or cold to be used later, at different conditions such as temperature, place, or power. TES systems are divided in three types: sensible heat, latent heat, and sorption and chemical energy storage (also known as thermochemical).
The flue gas from the engine and the compressed air from the reservoir are both fed into the heat exchanger and recovered (Fig. 11). The PCM proposed was a composite consisting of an inorganic salt melting at 210 °C and a ceramic matrix.
The pressure loss in the effectiveness of heat exchanger also affects heat exchanger performance. In addition, due to changes in the pressure in compressed air storage during energy storage and release process and changes in operating conditions, the air mass flow also changes, which also leads to changes in the effectiveness of heat exchanger.
Right: Thermo-chemical energy store is delivering heat for charging the combistore. The thermo-chemical energy store has to ful l two functions. It must provide a storage reservoir for the material and a reactor where the heat and mass transfer take place during the endothermic or exothermic reaction.
plate heat exchanger was developed. This model provides a di mensions, and component parts. pipe systems. These plates are used to increase t he surface from one fluid to another fluid. exchanger where many piping holes are created her. model to perform the operation.
