condenser are generally water cooled, as mentioned previously, and are of the shell and tube type.
A typical modren unit is shown in 9.4 in which it will be seen that the refrigerant passes over the tubes and the cooling water is passed through the tube.
in the case of sea water cooled condensers it is usual to have a two-pass arrangement through the tubes.
The sea water side maintenance mentioned for coolers in chapter 7 applies also to this condenser
