Type of article: Article, IJR article

Summary

A novel experimental technique has been developed to study a three-pressure absorption refrigeration cycle using R600-DMF as the working pair. The third (or the intermediate) pressure is obtained by employing a liquid-gas ejector between the absorber and the evaporator. Pilot plant studies showed that it is possible to obtain high COP (0.4) when compared with a conventional two-pressure cycle. Parametric studies on the COP and the recirculation ratio have been made. A mathematical model has been developed and the results obtained have been compared with those obtained experimentally. The important result is that higher COP values could be obtained at lower generator temperatures.
