Résumé

A packaged ammonia-water absorption chiller using a waste-heat stream and operating at severe ambient conditions is developed and experimentally evaluated. The chiller is designed to provide 2.6 kW of cooling at an ambient temperature of 51.7°C. The system is directly coupled to exhaust from a diesel generator to drive the absorption cycle. The absorber and condenser reject heat directly to ambient air. An autonomous control system is also developed and demonstrated experimentally. System performance is measured at ambient temperatures of 35 – 52°C, delivering cooling duties of 2.5 – 2.1 kW, with overall coefficients of performance (COPs) of 0.39 – 0.30. Performance limitations and areas for future development are discussed.
