What is a Condenser with Subcooling?

Horizontal Condenser with sub-cooling is a shell and tube heat exchanger in which the tube orientation is in Horizontal manner. When the vapors are allowed to condensed, the phase changes from gas to liquid. When this liquid is further cooled down to a much lower temperature, we call it as sub-cooling.

What is the significance of Horizontal Condensers?

In horizontal condenser with the vapors condensing over the tubes, the vapors are assigned on the shell side and during the heat transfer process, the condensed liquid forms a film all over the length of tube. The condensed liquid's temperature is further lowered and this phenomenon is called as the sub-cooling.
