Energy storage and simultaneous charging and discharging

Can simultaneous charging and discharging process be used in heat exchangers?

However, the work on the cases of simultaneous charging and discharging (SCD) process receives attention in just recent 15 years and is still inadequate. To the authors’ best knowledge, Liu et al. studied an SCD process in a heat pipe heat exchanger with PCM in 2006.

Does a latent TES system perform a simultaneous charging/discharging performance?

Simultaneous charging/discharging performance for a latent TES system is studied. Heat transfer rate is sensitive to flow rate combinations of cooling/heating water. Direct heat transfer between cooling/heating water is found in the stable state. System reaches stable states in 7500 s for initially solid phase change material.

Does a latent thermal energy storage system have thermal performance?

Conclusion The thermal performance of a latent thermal energy storage system is experimentally investigated during the simultaneous charging and discharging process.

Do TES systems need to be charged and discharged simultaneously?

To avoid frequent switches between the charging/discharging mode and to keep a continuous operation, TES systems need to be charged and discharged simultaneously. However, the work on the cases of simultaneous charging and discharging (SCD) process receives attention in just recent 15 years and is still inadequate.

What is the balanced charging/discharging power?

The balanced charging/discharging power is approximately 52 W. By comparison of Fig. 6 and Fig. 8 (b), it can be seen that the balanced power is still lower than that under the equal flow rate. It is noted that the initial charging power decreases to approximately 130 W, owing to the reduction of the charging flow rate.

Why is the ESU charged and discharged simultaneously?

Unequal charging/discharging flow rates Different flow rate combinations of the heating water and cooling water can affect the thermal behavior of the ESU. Accordingly, the ESU is charged and discharged simultaneously under two unequal flow combinations of heating and cooling water.
