This paper deals with an experimental study carried out to investigate the influence of DC electric fields on the performance of a fin and tube evaporator under frosting conditions. Several experiments are carried out measuring frost mass, air-side pressure drop and cooling capacity for different applied voltage, air velocity and evaporation temperature. Results show that the electric field reduces the frost mass and air-side pressure drop whereas it increases the cooling capacity. Finally, with a superimposed electric field, the overall energy consumption of the refrigerating unit reduces when referred to the same refrigerating effect. (C) 2011 Elsevier Ltd and IIR.
