Enhanced Non-Imaging Solar Concentrator for a Small Scale Drying in Buildings

Building energy conservation technologies and developing green buildings have been essential priorities in the last decade. Building integrated clean cooking and heating systems using the Sun's energy can play a vital role in green buildings for several applications. This paper reveals the improved design of the prototype of non- imaging solar concentrator, named as BISC and its possible use for clean drying in buildings. The small prototype of the BISC is experimented under field conditions utilizing simplified thermal analysis for its performance. The results show that the BISC able to achieve a temperature in the range of 59-74 °C, in the open drying operation. It ensures the potential for highly possible use in green buildings for drying with close drying operation, and other heating applications, such as cooking.
