Energy and Exergy Analysis of Evacuated Tube Solar Air Heater for Air Heating Applications
摘要
In today’s world, energy has become one of the basic infrastructures for economic development. Making use of solar energy in every sphere of development is essential to keep the environment clean and reduce dependency on fossil fuels. The primary objective of this research work is to conduct a performance assessment of an evacuated tube solar air heater system installed at the lab. The paper discusses the energy and exergy analysis of a 8 Sq. Mt Solar Evacuated Tube Collector (ETC) for the climatic conditions of Surat city, India. Various performance parameters like useful energy gain, collector's energy and exergy efficiency, and sensible energy storage for the ETC are worked out with different air mass flow rates. The hot air produced by the evacuated tube solar air collector can be used for various process heat applications such as space heating, food processing, dairy production, sun drying, and water desalination.
