This paper describes an attachment device to be installed in a basin-type solar distiller, which improve performance by enhancing condensation and internal convection. The device is composed of an electrode system of a thin metal wire and two metal pipes of which surface temperature is kept low by flowing cool water inside the pipes. As high voltage is applied between the wire and the pipes in high temperature and high humidity air, ionic wind blows from the former toward the latter. Water vapor in the wind condenses on the outer surface of the pipes when it collides with them. And the wind passing through between the pipes causes forced convection in the distiller. The performance of blower and condensation enhancement are examined experimentally on the optimal placement of the electrodes described in the previous paper by the authors. The experimental conditions are adopted such as 80, 60, 40℃ in nominal environmental temperature, 60, 40, 20℃ in nominal temperature of condensation surface with some exceptions, 90% in nominal relative humidity, and 18-26 kV in applied voltage. As a result, the effect of the ionic wind on the condensation enhancement and the blowing performance curves for the above conditions are clarified. Efficiency based on total pressure drops 30 % relative to the value under condition of normal temperature and humidity. Ionic wind increased the amount of condensate by more than 1.8 times, ratio of latent heat for condensation to electric power consumption for ionic wind generation is obtained up to approximately 560 times maximum. The experimental results shows that the ionic wind is effective for performance improvement of the distiller.
