Function of heat exchanger?
Heat Exchanger - Use And Purpose A heat exchanger is significant in the process of transferring heat from one chamber to another or from one industrial process to a secondary process. Most heating units for home heating include a heat exchanger that involves the transfer of fuel, i.e., oil, coal or natural gas, into heat for circulation and temperature control. Thus, most furnaces and boilers include a heat exchanger as part of the heating system. Heat Exchanger - In Industrial Processes A heat exchanger in an industrial process is a multi-chamber vessel designed at specific ranges of temperature, pressure and where applicable, fluid flow conditions. In certain industrial processes, heat exchangers circulate fluids that are flammable, toxic, dangerous and lethal to humans. This is the reason proper maintainence and precautions, such as draining and/or purging must be taken if a heat exchanger unit is opened for any reason. Types of Heat Exchangers There are several types of heat exchangers. Each of these types can be reconfigured according to specifications and use. There are shell type heat exchangers, front end stationary head types and rear end head types. How air or fluid is exchange by rate of flow is also a significant factor in efficiency of a heat exchanger. When purchasing a heat exchanger, to establish standard terminology for heat exchanger prior to an installation, the unit should be accompanied by a heat exchanger nonmenclature. This is basically identification of typical parts, connections and locations found in schematic diagrams for installation. General Parts Of A Heat Exchanger In most cases, a heat exchanger has a head, stationary or shell as well as tubes, stationary tubesheets, channel cover, flanges, impinger plate, support saddle and vent, drain and instrument connections. Manufacturers assign specific serial numbers to each heat exchanger that are unique for identification and replacement purposes. Generally, a furnace or boiler manufacturer provides an operations and maintenance manual that includes the type and serial number of the original heat exchanger. Replacement of a heat exchanger should be done by a professional, licensed HVAC specialist to avoid hazards. Maintaining A Heat Exchanger The heat exchanger unit should be regularly cleaned, calibrated and maintained.

Heat exchanger for ammonia absorption refrigeration system?
there are two type of heat exchanger in absorption refrigeration, first is liquid heat exchanger and other is gas heat exchanger.both heat exchanger function is same, to transfer heat (hot medium to cold medium) without violate second newton law of thermodynamics. liquids heat exchanger is between boiler and absorber vessel mean while gas heat exchanger between evaporator and absorber.
Exchanger is not transfer heat why?

What is heat exchanger duty?
The duty of a heat exchanger can be defined in an easy way as "The amount of heat exchanged from a fluid at a higher temperature to the fluid at lower temperature in unit time by a heat exchanger is called its duty"
Why Expansion bellows are required in heat exchanger?
expension belows are used for heat exchanger to avoid thermal stress
What is the relationship between the efficiency of a heat exchanger and its surface area?
The efficiency of a heat exchanger is directly proportional to its surface area. This means that a larger surface area allows for more heat transfer, resulting in a more efficient heat exchanger.
When is it necessary to schedule a heat exchanger replacement?
It is necessary to schedule a heat exchanger replacement when the current heat exchanger is damaged, malfunctioning, or no longer efficient in transferring heat effectively. Regular maintenance and inspections can help determine when a replacement is needed.
What is difference between condenser and heat exchanger?
A heat exchanger is a device that transfers heat from one fluid to the others. A condenser is simply a heat exchanger. It compresses refrigerants into a hot gas to then condense them into a liquid. Majorly condenser is used to cool the required vapor and heat exchanger is used to heat the required liquid.
Where is the dollar plate on a heat exchanger?
It's the flat, flanged cover on the front (and sometimes the rear) of a shell & tube heat exchanger.
How you can increase the retention time in shell and tube heat exchanger?
the most effective way to do so is to reduce the flow of the heat exchanger
