A Shell and Tube condenser, a frequent component in extensive refrigeration and air conditioning setups, employs water cooling.
Within this configuration, the refrigerant circulates within the shell, surrounding the tubes.
Cooling water traverses the interior of the tubes, thereby absorbing heat from the refrigerant.
Heat transfers from the high-temperature refrigerant to the lower-temperature water flowing through the tubes, initiating the refrigerant's condensation.
Consequently, the refrigerant resides in the shell while water passes through the tubes, reversing the typical flow.
Air is not a factor in the operation of a shell and tube condenser.
Thus, option (B) is the accurate selection.
