Description:
The major deterrent to the large-scale deployment of the solar air heaters is their relatively high initial capital cost. Also, desired efficiency levels are still in the offing to make the system perform optimally. In the present case, several designs of air heaters developed either on a pilot scale or commercial level have been thoroughly assessed from key techno-economic considerations. These include the corrugated absorber, corrugated single pass, double pass and triple pass air heaters, finned air duct and packed bed air heaters.

Special Features:
The key feature of the above-mentioned study is manifested in the theoretical optimization of several critical parameters like the air flow rate, duct Departmenth and length for pre-fixed collector material. So, the net result is in the form of availability of optimally suited combinations, which can be tried to arrive at the most suitable system design choice at an affordable system cost.
