Abstract

The influence of electro-convection with different parameters of electric field intensity on the air cooler efficiency under conditions of frost formation was studied. The electro-convective air flow was faster as compared to the cooler operation without electro-convection. The higher the relative air humidity and the intensity of the electric field, the greater the effect of electro-convection upon the external heat exchange of the air cooler. An equation is suggested for the estimation of frost thickness, specific heat flow and coefficient of heat transfer, and thus could be used in designing air coolers operating under electro-convective heat exchange.
