| Research Abstract |
This study examined feasibility of an oil separation by Coulomb force with electric charge of oil mist in order to decrease an oil delivery from a refrigerant compressor. In the refrigerant atmosphere, although an inception voltage of Corona discharge increases with pressure, the oil droplet can be charged by the Corona discharge and separated by the Coulomb force. When an induction charge is applied to charge the droplet, it can be separated at lower voltage. It is observed that oil having large polarity such as PAG oil deforms by polarization in the electric field.
