“…Functions for PCMs in solar thermal systems mainly include design of the geometrical parameters of PCM storage container (Afshan et al, 2020), hybrid materials manufacture (Wang et al, 2013), heat transfer enhancement (Qiu et al, 2019), and stabilization in solar thermal energy supply (Aramesh & Shabani, 2020). Raul et al (Raul et al, 2018) conducted the parametrical analysis on a latent PCM unit for solar thermal energy storage, and obtained the maximum efficiency of 75.69%.…”

In today’s world, the energy requirement has full attention in the development of any country for which it requires an effective and sustainable potential to meet the country’s needs. Thermal energy storage has a complete advantage to satisfy the future requirement of energy. Heat exchangers exchange heat in the thermal storage which is stored and retrieved later or can be used as a pre-heating or post-heating devices to save energy. Criteria of design of heat exchangers for various thermal energy storage applications along with their various components are being elaborated. The latent heat thermal energy storage in a mass application has got many advantages over the sensible heat storage. The existing approaches in the design, integration and application of phase change materials (PCMs) are explored by experimenting on a prototype of a single heat exchanger module and analysing all the design aspects to get a significant idea and the analysis needed while charging and discharging the heat exchanger.

A Review on the Performance Indicators and Influencing Factors for the Thermocline Thermal Energy Storage Systems

Thermal energy storage (TES) system plays an essential role in the utilization and exploitation of renewable energy sources. Over the last two decades, single-tank thermocline technology has received much attention due to its high cost-effectiveness compared to the conventional two-tank storage systems. The present paper focuses on clarifying the performance indicators and the effects of different influencing factors for the thermocline TES systems. We collect the various performance indicators used in the existing literature, and classify them into three categories: (1) ones directly reflecting the quantity or quality of the stored thermal energy; (2) ones describing the thermal stratification level of the hot and cold regions; (3) ones characterizing the thermo-hydrodynamic features within the thermocline tanks. The detailed analyses on these three categories of indicators are conducted. Moreover, the relevant influencing factors, including injecting flow rate of heat transfer fluid, working temperature, flow distributor, and inlet/outlet location, are discussed systematically. The comprehensive summary, detailed analyses and comparison provided by this work will be an important reference for the future study of thermocline TES systems.
