The heat exchanger (Hex) in a LAES system using liquid phase working mediums for cold energy storage (CES) works discontinuously for the intermittent characteristic of the LAES. Variable temperature distribution exists in the Hex for CES (Hex-CES) in the intermittent process, and degrades the performance of the CES unit.
Internal and external fin heat transfer enhancement technique for latent heat thermal energy storage in triplex tube heat exchangers Appl. Therm. Eng., 53 ( 2013 ), pp. 147 - 156, 10.1016/j.applthermaleng.2013.01.011
The application of a latent heat thermal energy storage (LHTES) system can effectively solve the problem of the mismatch between the energy supply and demand. However, most studies focus on the traditional cylindrical configuration with a low heat storage rate, which limits the wide application of LHTES systems.
The triplex-tube heat exchanger (TTHX) with phase change materials (PCMs) has been found to be a very efficient energy storage application for this purpose. However, the low thermal conductivity of PCMs used makes them unable to give the desired response for storage and recovery.
