| 제목 | 암모니아수를 이용한 고효율 Kalina Power-cooling cogeneration system의 Exergetic/exergoeconomic 분석 |
| 초록 | Recent technical developments have made it possible to generate power and cooling using Kalina cycle (KC) utilizing low grade heat sources such as industrial waste heat. Kalina cooling-power cycle (KPCC) is a novel case of these technologies which combines KC with NH3-H2O absorption chiller. Exergy analysis is performed to analyze and compare the system from exergy view point considering both chemical and physical exergy of NH3-H2O. The unit cost of power-cooling generation is obtained through exergoeconomic assessment. According to the results the exergetic efficiency (12.32%) and unit cost value (0.0055$/s) of the system in comparison with KC were 6.8% higher and 10.9 % lower than the KC system, respectively. Therefore, KPCC despite cooling- power cogeneration has a better performance when compared to KC. Performance optimization based on exergy analysis can begin from absorber and superheater where the significant exergy destruction happens.
