Theoretical And Experimental Study On The Solubility Of R161 Mixed With POE

Since depleting the ozone layer and causing "greenhouse effect", according to the Montreal Protocol and the relevant amendment and the "Kyoto Protocol", the refrigerants which contents hydrochlorofluorocarbons (HCFCs) will be phased out. Hydrofluorocarbons (HFCs) and their mixtures are considered to be promising candidates for replacement of HCFCs because their ozone depletion potentials are zero. Studies on thermodynamic properties of HFCs have got a great achievement since 1997. Our group has proposed a series of mixed refrigerants with a main component of R161. At present, the members of our group have completed the experimental tests of PVTx, vapor-liquid equilibrium, flammability, and the cycle performance of the new refrigerants. In this work, the author put focus on the solubility of R161 in POE, and the following work has been done:Firstly, the activity coefficient models were studied. Through perusing large number of documents, the method which was used to correlate the VLE and LLE data was apprehended. Program, using the four different activity models, was made for correlating the VLE data.Secondly, measurement of the VLE data of R161 mixed with POE was completed. After mending the existing experiment, the VLE data of R161 in POE lubricant was measured at temperature between 253.15 and 333.15K.Thirdly, Using the program made by the author, the VLE data was correlated and the interaction parameters was gained.
