Résumé

Application of ejector systems for heat recovery and transform this heat for usable cooling power is one of the most effective and economic way for utilisation of waste heat. This is an exceptionally attractive technological solution for companies with large amount of low-temperature energy sources. The ejector system as one of the few technologies is able to operate with temperature of heat source lower than 80 °C. The paper provides with the results of experimental investigations of the ejector refrigeration system applied in industrial company for recovering waste heat from reciprocating compressors units. The ejector systems have been tested for operation with extremely low GWP and non-flammable R1233zd(E) and R1234zeE refrigerants. Two systems have been studied, one with the capacity of 200 kW and second one with capacity of 600 kW. The system has achieved the entrainment ratio of up to 0.24 which allowed for obtaining up to 45 kW of refrigeration capacity for R1233zdE. In the case of R1234zeE the entrainment ratio up to 0.30 was achieved and cooling capacity of 144 kW was produced.
