Power station energy storage heat exchanger

What is a plate heat exchanger?

A plate heat exchanger is a component of efficient and low-cost energy storage systems, in particular for thermal and mechanical solutions. Alfa Laval's proven and reliable plate heat exchangers are able to handle cyclical duties with reversible flows, across a wide range of different temperatures and pressures, as well as energy storage medias.

How effective is a heat exchanger?

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.

How does pressure affect heat exchanger performance?

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.

Can compact heat exchanger design overcome PCM thermal conductivity limitations?

Results show that reducing the PCM-encasement thickness yields substantially better performance than by improving the thermal conductivity, thereby demonstrating the potential for compact heat exchanger design to overcome the PCM thermal conductivity limitations. 1. Sol. Energy Mater.

What are the future research directions of thermal energy storage in caes?

The future research directions of thermal energy storage in CAES are discussed. Compressed air energy storage (CAES) is a large-scale physical energy storage method, which can solve the difficulties of grid connection of unstable renewable energy power, such as wind and photovoltaic power, and improve its utilization rate.

What is a semi-welded plate heat exchanger?

A semi-welded plate heat exchanger is a type of heat exchanger built for demanding duties. Alfa Laval's unique gasket sealing system enables enhanced, long-term performance in applications with high pressures and temperatures.
