Evaporator Water Defrost

This is the oldest method for defrosting serpentines, because through a natural fluid, the serpentine is sprayed with micro-jets of water, providing the liquefaction of the ice. The minimum flow rate of water circulation is 2 L / s for each m2 of face area. The water, then cooled, is collected and reheated to return to the evaporator at a minimum temperature of 18 ° C. For this, the condenser of the system can give the necessary energy to reheat the defrost water. Excessive water temperatures are inadvisable due to the formation of mist in the chamber. The main advantages of water-melt, compared to other means of defrosting,
