AFFECTION OF NANO-FE3O4 ON THE SATURATED PRESSURE OF MIXTURE HFC134a/MINERAL OIL
An experiment rig was assembled and used to measure the saturated pressure of a refrigerant. Since the diameter of nano-particle is quite small, and nano-particle has specific properties, such as the surface action, volume action, quanta-size action and tunnel action, the saturated pressure of mixture HFC134a/mineral oil is affected by adding nano-Fe3O4. By measuring the saturated pressures of mixture HFC134a/mineral oil and mixture HFC134a/mineral oil/nano-Fe3O4, it was found that the saturated pressure curve of mixture HFC134a/mineral oil/nano-Fe3O4 was higher than that of mixture HFC134a/mineral oil. It means that the coefficience of performance of an HFC134a refrigeration system would increase when the working fluid was treated by nano-Fe3O4. This inference was exparimental validated in a refrigerator.
