Abstract

This study examines the potential of salt gradient solar pond (SGSP) as a sustainable energy system for thermal energy storage. The research investigates the use of an East-West (EW) reflector and coal cinder additive (CC) to enhance the energy efficiency of a trapezoidal salt gradient solar pond (SGTSP). The study involved designing, fabricating, and analyzing the SGTSP systems with EW and CC, compared to the standard SGTSP system, from an energy point of view. Additionally, the study provides shading area analysis based on the SGSP system's slant angle, offering valuable insights into its performance for low-grade heat source thermal applications. The findings indicate that the EW reflector significantly increased the average solar intensity by 33.2%, while the addition of coal cinder additive raised the average temperature of the lower convection zone by 24.1%. The SGTSP system with EW reflector and coal cinder additive (SGTSP-EWR&CC) demonstrated a maximum average temperature of 83.85°C and a 42% higher energy efficiency in the lower convection zone compared to the conventional SGTSP system (SGTSP-C). Overall, the study showcases the potential of SGTSP as a sustainable energy system for thermal energy storage and provides practical strategies for enhancing its energy efficiency.

通过能量分析考察东西向反射镜与煤渣在梯形太阳能池中的协同利用

本研究探讨了盐梯度太阳能池(SGSP)作为一种可持续的热能储存能源系统的潜力。研究了利用东西反射镜和煤渣添加剂来提高梯形盐梯度太阳能池(SGTSP)的能效。该研究涉及设计、制造和分析具有EW和CC的SGTSP系统，并从能量的角度与标准SGTSP系统进行比较。此外，该研究还提供了基于SGSP系统倾斜角度的遮阳面积分析，为其在低等级热源热应用中的性能提供了有价值的见解。结果表明:EW反射面使平均太阳强度提高了33.2%，煤渣添加剂的加入使下对流区平均温度提高了24.1%。与传统的SGTSP系统(SGTSP-C)相比，添加了EW反射镜和煤渣添加剂的SGTSP系统(SGTSP- ewr&cc)的最高平均温度为83.85℃，低对流区的能量效率提高了42%。总体而言，该研究展示了SGTSP作为可持续能源系统的潜力，并为提高其能源效率提供了切实可行的策略。
