Study on The Effect of Different Plenum Chamber Coefficients on Frosting of Air-cooler

The performance of the air-cooler in the refrigeration system plays a key role in improving the energy efficiency. Here, the plenum chamber coefficient was defined to study a possible way of enhancing the refrigeration system performance. In order to investigate the influence of the plenum chamber c...
