Summary

In this work, an absorption-compression refrigeration system coupled a R22 compression refrigeration subsystem with a Li-Br absorption refrigeration subsystem is presented. Numerical and experimental works are considered for the purpose of highlighting. The performance characteristics of the absorption-compression refrigeration system are carefully analysed, which has energy-saving potential. The investigation is carried out over the generating temperature (Thi) from 60 to 90°C, the cooling water temperature (TCi) from 30 to 38°C, and the chilled water temperature (Te) from 8 to 18°C. According to the analysis of performances, the absorption-compression refrigeration system should be adopted when low-grade heat is free. The global COP and the Qg,EV are 2.56 and 1.9 times as large as those of the traditional one, respectively, at the generating temperature is 80°C, the cooling water temperature is 34°C and the chilled water temperature is 10°C.
