water-cooled condenser

In a shell-and-tube type water-cooled condenser used in a vapor-compression chiller, the use of 3/4-inch copper tubes with external fins is a thermal and economic choice. Although the refrigerant flows on the shell side and cooling water flows inside the copper tubes, the external surface of the tubes still plays an important role in improving heat transfer efficiency. The main reason is that the heat transfer coefficient on the refrigerant side, especially during condensation, is relatively low and must be...

What Techniques Maximize the Service Life of Shell-and-Tube Heat Exchangers?

Shell-and-tube heat exchangers, owing to their simple structure, enable effective heat transfer between different fluids and are therefore widely used in many industrial applications, including hydraulic-oil coolers. By implementing certain techniques, the operational lifespan of a shell-and-tube heat exchanger can be significantly extended, preventing unexpected production downtime and avoiding additional repair costs. The following sections examine key strategies for increasing the service life of shell-and-tube exchangers. Selecting a Shell-and-Tube Exchanger Based on Fluid Type One of the most impactful measures to enhance...
