This study investigates the performances of five low GWP (Global Warming Potential) refrigerant/[P6

6

14][Cl] working pairs in the compression-assisted single-effect absorption system. The studied refrigerants include hydrocarbon (HC) R290 and R600a

hydrofluoro-olefin (HFO) R1234yf

R1234ze(E)

and R1233zd(E). The NRTL model was utilized to correlate the vapor-liquid equilibrium data of five working pairs

and the performance improvement of the compression-assisted absorption system was verified against the traditional single-effect absorption system. Based on this

the effects of the generation and absorption temperatures on COP

exergy efficiency

and circulation ratio of five working pairs were analyzed. The results show that the implementation of a compressor in front of the absorber may significantly increase the COP of the system. Of the five working pairs

R290/[P6

6

14][Cl] exhibited the best performance; while R1233zd(E)/[P6

6

6

14][Cl] had the worst performance

and the maximum differences in the COP and exergic efficiency were 0.277 4 and 0.224 5

respectively. As the generation temperature increased

the COP and exergy efficiency of all working pairs had maximum values

whereas the circulation ratios decreased monotonically. As the absorption temperature increased

the COP and exergy efficiency of all working pairs decreased

whereas the circulation ratios increased.
