What Are Heat Exchangers Used For?

What is difference between heat exchanger and condenser?

A condenser is a subset of the wider term “heat exchanger”.

Condenser is also a heat exchanger.

The main difference between these two are that in heat exchanger only heat is transferred without phase change and in condenser heat is transferred along with the phase change..

What are the types of heat exchanger?

Types of Heat ExchangersShell and tube heat exchangers.Double pipe heat exchangers.Plate heat exchangers.Condensers, evaporators, and boilers.

What are shell and tube heat exchangers used for?

Shell-and-tube heat exchangers. Our shell and tube heat exchangers are used in many comfort and industry applications for heating and cooling fluids. They consist of a shell with traditional plain tubes or enhanced surface tubes for high thermal performance.

How do I choose a heat exchanger?

The following criteria can help in selecting the type of heat exchanger best suited for a given process:Application (i.e. sensible vapor or liquid, condensing or boiling)Operating pressures & temperatures (including startup, shutdown, normal & process upset conditions)More items…

What are the two types of heat?

The three types of heat transfer Heat is transfered via solid material (conduction), liquids and gases (convection), and electromagnetical waves (radiation). Heat is usually transfered in a combination of these three types and seldomly occurs on its own.

How can you make a heat exchanger more efficient?

In general, the most efficient way to install a heat exchanger is to flow the fluid in a countercurrent arrangement (so that if the coolant travels from left to right and the hot fluid travels from right to left), and for shell and tube heat exchangers, The agent should enter the lowest inlet position (as shown above) …

Is radiator a heat exchanger?

Radiators are heat exchangers used to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are constructed to function in automobiles, buildings, and electronics.

How do you calculate effective heat exchanger?

The effectiveness (ϵ) of a heat exchanger is defined as the ratio of the actual heat transfer to the maximum possible heat transfer. Qmax is the minimum of these two values i. e.

How does a tubular heat exchanger work?

Tubular Heat Exchangers. The Flat Tube Heat Exchanger is an air to air heat exchanger operating on the principle of forced draught convection. Process gases pass over the outside surfaces of the heat exchanger elements. … On applications where there is a relatively constant inlet heat load energy recuperation is possible …

What is the most effective heat exchanger?

Plate exchanger is the most efficient due to turbulent flow on both sides. High heat-transfer coefficient and high turbulence due to even flow distribution are important. However, a plate heat exchanger regenerator is restricted to low viscosities. With high viscosities, a special tubular may be required.

What is TEMA standard?

TEMA stands for “Tubular Exchangers Manufacturers Association” and is a set of standards that were developed by leading shell and tube manufacturers. These standards define the style of heat exchanger and the machining and assembly tolerances.

Is boiler a heat exchanger?

Since exchange of heat occurs in the Boilers, Boilers can be termed as a Heat Exchanger. But there’s more to a Boiler, than just being a Heat Exchanger. … But A Boiler generates heat through chemical reaction of the fuel, and exchanges the heat with the water to produce steam or heated water depending on the application.
