What are the applications of heat exchanger?

Such types of heat exchangers are used predominantly in air conditioning, humidification, industrial hot water heating, water cooling and condensing plants.

In which service double pipe heat exchanger should be used?

Double-pipe exchangers are used with clean fluids where low heat transfer area is required with high temperature and high pressure (500 psig). Tube configurations are shown in Fig.

Where would you use shell and tube double pipe heat exchangers?

When to use double pipe heat exchanger and shell and tube heat exchanger? Double pipe heat exchangers are used when the heat transfer area is small say up to 14 m2. If we connect them in series to increase the heat transfer area it will require much space as well the pressure drop will be higher due to more fittings.

What are the uses and applications of a shell and tube heat exchanger?

Application of shell and tube heat exchanger One of the most common applications is the cooling of hydraulic fluids, Chemicals, and oils. With the right choice of materials, they can also be used to cool or heat other mediums, such as swimming pool water or charge air.

Why heat exchanger is used in most of the solar energy based application?

Solar water heating systems use heat exchangers to transfer solar energy absorbed in solar collectors to potable (drinkable) water. Solar heating systems usually use copper, because it is a good thermal conductor and has greater resistance to corrosion.

What are the examples of heat exchanger?

Air preheaters, economizers, evaporators, superheaters, condensers, and cooling towers used in a power plant are a few examples of heat exchangers.

What are the characteristics of double pipe heat exchanger?

It consists of concentric pipes separated by mechanical closures. Inexpensive, rugged and easily maintained, they are primarily adapted to high-temperature, high-pressure applications due to their relatively small diameters. Double pipe heat exchangers have a simple construction.

Why is a double pipe heat exchanger not ideal for high energy transfer applications?

Disadvantages of Double Pipe Heat Exchangers It does not mean that they cannot be used in parallel flow. They have limitations in heat transfer rather than complicated designs and should be used in low heat duties. Leaking is more often in this type (paired with more units)

What is the difference between double pipe and shell and tube heat exchanger?

Double pipe heat exchanger consists of two concentric pipes of different diameters. One pipe is for hot fluid and another is for cold fluid. Shell and tube heat exchanger consists of a shell in which large number of parallel tubes are present. One fluid hot or cold flow in shell and other hot or cold flow in the tubes.

What are the applications of shell?

Examples of shell script applications

• Automating the code compiling process.
• Running a program or creating a program environment.
• Completing batch.
• Manipulating files.
• Linking existing programs together.
• Executing routine backups.
• Monitoring a system.

What industry uses shell and tube heat exchanger?

Shell-and-tube heat exchangers are used in the chemical, food, oil and gas and other fields. They are used as evaporators and condensers.

How does a double pipe heat exchanger work?

The double pipe heat exchanger works via conduction, where the heat from one flow is transferred through the inner pipe wall, which is made of a conductive material such as steel or aluminum. The double pipe heat exchanger is often used in counterflow, where its fluids move in opposite directions (as shown above).
