Evaporation Condenser Induced circulation

                                          Evaporation  Condenser Induced circulation

   An Evaporative condenser The function of a cooling tower. It is of two types forced circulation type and induced circulation type. It consists of a casing enclosing coil , water , tank , float valve and a spray pump outside  the casing.

     The spray pump circulate the water from water take at the bottom of the unite to the spray nozzle over the refrigerant coil. The fan pull or forces the air through the coil and through the water being sprayed over the coil .The heat from  the refrigerant is transmitted the through the metal coil to the water by evaporating a portion of it.

          The drift eliminator (water eliminator ) prevent the water droplets from beings carried out with the air water droplets from being carried out with the air the float control valve maintain a constant level of water in tank As water evaporate , the level of water in the falls down and float valve open and make up water enter in bottom tank A bleed -off line is a small line leading from the pump discharge directly to the sewer . Since an evaporative condenser evaporates large Quantity of water , remaining water becomes increased. The bleed -off line assures that enough water will be pump to the sewer to prevent the concentration from becoming too great.
