In this paper, the solubilities of 1,1,2,2,3,3,3-heptafluoropropane (R227ea), 1,1,1,3,3,3-hexafluoropropane (R236fa) and 1,1,1,3,3-pentafluoropropane (R245fa) in trihexyltetradecylphosphonium bis(2,4,4-trimethylpentyl)phosphinate ([P(14)666][TMPP]) were correlated with the non-random two-liquid (NRTL) equation with relative mean deviation less than 3.1%, respectively. The thermodynamic performances of the single stage absorption refrigeration systems using R227ea/[P(14)666][TMPP], R236fa/[P(14)666][TMPP] and R245fa/[P(14)666][TMPP] as the working pairs were simulated. When the absorption refrigeration systems has an ideal heat recovery exchanger, R245fa/[P(14)666][TMPP] shows better performances than NH3/H2O while R236fa/[P(14)666][TMPP] and R227ea/[P(14)666][TMPP] can work at much lower generator temperature than NH3/H2O. |
