| Summary: | The performance of a double pass solar air heater was experimentally
investigated using four different configurations. First configuration
contained only absorber plate whereas copper tubes filled with thermal
storage medium (paraffin wax) were added on the absorber plate in the second
configuration. Aluminum and steel rods as thermal enhancer were inserted in
the middle of paraffin wax of each tube for configurations three and four
respectively. Second configuration provided useful heat for about 1.5 hours
after the sunset compared to first configuration. Configurations three and
four provided useful heat for about 2 hours after the sunset. The maximum
efficiency of about 96% was achieved using configuration three (i.e. using
Aluminum rods in the middle of copper tubes filled with paraffin wax). |
