In air-cooled condensers, the heat released by refrigerant condensation is entrained by the air. Air cooled condensers are used in small Freon refrigerators, such as refrigerators, freezers, window air conditioners, air conditioners for automobiles and rail vehicles and refrigerated trucks. Air-cooled condensers are mostly serpentine, refrigerant vapor condenses in the tube, the air flows through the tube. According to the different modes of air movement, it is divided into natural convection and forced convection.
In an air-cooled condenser, the heat released by the refrigerant is taken away by the air. The air can be either natural convection or forced flow using a fan. This type of condenser is used in Freon refrigerators for inconvenient or difficult water supply, so these condensers consume little water. It is the preferred condenser in the area of air-dry, low water quality and temperature. This type of condenser according to their different structure can be divided into evaporating and pouring two kinds.
Due to the high summer temperatures (up to 35 ° C), condensing temperatures are also higher (up to 40-50 ° C) when using air-cooled condensers. So it is suitable for the condensing pressure lower refrigerant (such as R12). The biggest advantage of air-cooled condensers is that they do not require cooling water and are therefore particularly suitable for water-scarce areas or where water supply is difficult.
