Abstract

ABSTRACT Development in solar air collectors have increased because of the renewable and non-polluting sources of energy. The present study focused on artificial roughness, vortex generators, thermal storage units, etc., which are employed to improve the performance of Solar Air Heaters (SAHs). Thermal efficiency of Double Pass Solar Air Heater (DPSAH) improved from 10% to 15% as compared to the Single Pass Solar Air Heater (SPSAH) and improves further using an integrated absorber with a heat storage unit. About 12% and 15% improvement in thermal and thermo-hydraulic efficiency was achieved using a rough absorber. Integrated absorbers with Composite Phase Change Materials (CPCMs) based heat storage is one of the new signs of progress to optimize the thermal efficiency of SAHs.

太阳能空气加热器的热性能和传热强化研究进展

摘要由于可再生和无污染的能源，太阳能空气收集器的发展迅速。本研究的重点是人工粗糙度、涡流发生器、储热单元等，这些都是用来提高太阳能空气加热器（SAHs）性能的。与单程太阳能空气加热器（SPSAH）相比，双程太阳能空气加热器的热效率从10%提高到15%，并使用带储热单元的集成吸收器进一步提高。使用粗吸收器实现了热效率和热工水力效率的大约12%和15%的提高。基于复合相变材料储热的集成吸收器是优化SAH热效率的新进展之一。

期刊介绍： Engineering and sustainable development are intrinsically linked. All capital plant and every consumable product depends on an engineering input through design, manufacture and operation, if not for the product itself then for the equipment required to process and transport the raw materials and the final product. Many aspects of sustainable development depend directly on appropriate and timely actions by engineers. Engineering is an extended process of analysis, synthesis, evaluation and execution and, therefore, it is argued that engineers must be involved from the outset of any proposal to develop sustainable solutions. Engineering embraces many disciplines and truly sustainable solutions are usually inter-disciplinary in nature.
