WATER-cooled condenser is a heat exchanger that removes heat from refrigerant vapor and transfers it to the water running through it. They exchange heat by REMOVING heat from one fluid and transferring it to another fluid. Following are the types of water-cooled condenser:Shell and tube TYPE condenserTube-in-tube condenserShell and coil type condenserNatural convection – It is a phenomenon due to which fluid flows naturally or freely i.e. without any forced means e.g. (fans, pumps, etc ). It flows because of some parts being HEAVIER than others. The FORCE behind it is the gravitational force.
