Vacuum Effect on the Performance of Solar Air Collector with Micro-Channel Absorber Plate
In this study, the effect of vacuum with micro-channel techniqueon solar air collector performance is investigated experimentally. Vacuumspace reduces the loss of heat for the absorption plate by conduction andthus improves the solar collector performance. It has been demonstratedthat the solar coll...

| description | In this study, the effect of vacuum with micro-channel techniqueon solar air collector performance is investigated experimentally. Vacuumspace reduces the loss of heat for the absorption plate by conduction andthus improves the solar collector performance. It has been demonstratedthat the solar collector is evacuated to 0.1 bar of pressure for absorber-tocover spacing of 4cm. An absorber plate was manufactured from Aluminummetal with 30 rectangular micro-channels (length 0.9, width 0.004, height0.0008 m) is constructed with measurements facilities of velocity,temperature and differential pressure. The tests are carried out indoor usingsolar simulator. Results showed that the performance of solar collectorincreases with vacuum about 2-5% than gained with non-vacuum utilizing amicro-channel absorber plate-black surface. |
