Abstract

An experimental study on the structural optimization of solar air compressor is conducted. The heating and cooling characteristics as well as the changes of solar energy utilization rate after installing a disturbing fan in the compressed air tank are tested and analyzed. The experimental results show that in the range of speed 2.0-6.7 m/s, there exists an optimal speed, which makes the solar thermal engine have the highest efficiency. Its cooling coefficient increases from 0.34-0.44 to 0.78-0.84, and the absorbent capacity of the compressor after cooling also increases significantly. According to the nominal solar energy utilization rate, compared with the ribbed heat-absorbing tube or smooth heat-absorbing tube without blower, the combined structure of blower and ribbed heat-absorbing tube has a great improvement. The improvement range is between 10.8% and 145.8%. Besides, the heat transfer enhancement effect of blower is obvious.
