Abstract
The 2,2,2-trifluoroethanol (TFE)+quinoline mixture was chosen as a potential working fluid used in an absorption chiller. Heat capacity was measured and correlated by a polynomial equation as a function of temperature and concentration, and the parameters of the regression equation were determined by a least-squares method. The cycle simulation for a double effect absorption cycle was carried out at various operation conditions. The appropriate operation condition and COP values were calculated for the absorption cycle by using the proposed working fluid. TFE+quinoline solution could be a promising working fluid as an alternative to the LiBr+H2O and H2O+NH3 systems based on the operation range and simulation results.
