It is cooled with water in advance that leading the cold device and condenser of the refrigeration system adopt the cooling way of the cooling water, use mainly for, supply water condition to be better entering angry temperature high and air handling capacity loud occasion, because it is influenced by environmental temperature factor and relatively small, it is relatively stable to export the air dew point. The condenser adopts the shell in charge ofing type, transfer to hotly and affectively and high-efficient and roll the tooth to manage, the cooling water leaves and is in charge of Cheng, use with the passing of time forming dirt to be apt to wash, freon walk shell Cheng, make condensation to be result in good state for a long time.</p>
