Analysis of Parabolic trough Collector with Various Reflectors
Keywords:
Parabolic trough collector, Reflectors, Air flow ratesAbstract
A solar powered air heating system using parabolic trough collector was experimentally
investigated. In this experimental setup, the reflected solar radiations were focused on absorber
tube which was placed at focal length of the parabolic trough. In this setup, air was used as
working fluid which collects the heat from absorber tube. To enhance the performance of parabolic
trough, collector with different type of reflectors were used. It was observed For Aluminum sheet
maximum temperature is 52.3ºC, which 24.22% more than steel sheet as reflector and 8.5% more
than Aluminum foil as reflector, also efficiency by using Aluminum sheet as reflector compared to
steel sheet as reflector is 61.18% more. Efficiency by using Aluminum sheet as reflector compared
to Aluminum foil as reflector is 18.98% more
