< p > < span =风格"font-size:14px">Solar collector is important component of active solar heating systems. It has been observed that the performance of flat plate collector improves appreciably by packing its duct with blackened wire screen matrices and this improvement is a strong function of bed and operating parameters. In this paper an experimental test setup is designed and fabricated. Performance evaluation of packed bed Solar air heater using wire mesh screen matrices and its comparison with conventional design has been done. Data collection at different mass flow rates for a number of configurations has been done. Further suitable recommendations have been made accordingly.
