3.3.Condenser
The condenser is an important device used in the high pressure side of a refrigeration system. Its main function is to transfer heat from the refrigeration system to condensing medium. The hot vapour refrigerant consists of the heat absorbed in the evaporator and the heat of compression added by the mechanical energy of the compressor. The heat from the hot vapour refrigerant in a condenser is removed first by transferring it to the walls of the condenser tubes and then from the tubes to the condensing or cooling medium. The cooling medium may be air or water or a combination of the two. The selection of a condenser depends upon the capacity of the refrigerating system, the type of refrigerant used and the types of cooling medium available.
