Experimental Study of the Circulation Air Volume of Recirculation Evaporative Cooling
MetadataShow full item record
This paper introduces the technology of re-circulation evaporative cooling (REC), which uses a portion of supply air as secondary air to make cool water used to indirectly cool outside air through a heat exchanger. The circulation volume of secondary air is one of the main factors that have an impact on the effectiveness of REC. According to the technology, a set of apparatus was set up. The cooling effect was tested under different circulation volumes of secondary air in summer. The test results show that the cooling effec-tiveness rapidly increases and then levels off with the increase of the ratio of circulation volume. We con-clude that there is a proper range of the circulation volume.
