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.
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
Does effectiveness of a heat exchanger depend on operation condition?
Yes it does. As with any device, a heat exchanger is designed to work within certain parameters. If the conditions exceed these limits, the effectiveness of the heat exchanger is compromised, and my wind up not functioning at all.
What is the factors that effect on number of tubes in shell and tube heat exchanger?
The factors that are affected by number of tubes in shell and tube heat exchanger is the rate of heat transfer and flow rate.
How do you passivate heat exchanger tubes and it is advisable.?
To passivate an exchanger gently pat the shell while whispering into a bleeder

Difference between heat exchanger and condenser?
actually there is no difference , infact condenser itself is a heat exchanger
What type of exchanger is used to condense a vapor by cooling it?
A heat exchanger.
What is the difference between a calorifer and a heat exchanger?
Calorifer is a heat exchanger, with a specific of air (or other gas) preheat. Usually is directly in a Duct installed. Heat Exchanger usually is separate unit.
What is the effect of overall heat transfer coefficient U to heat exchanger performance?
The equation for the duty of a heat exchanger is:Q=U*A*LMTDwhere:Q is the dutyA is the overall heat transfer areaLMTD is the log mean temperature difference.generally when desiging heat exchangers the desired duty is known, as are the desired inlet and outlet temperatures. Therefore we solve for A to find the overall heat transfer area.A= Q/(U*A*LMTD)If we hold Q and the LMTD constant, you can see that a larger overall heat transfer coefficient U, will result in a small exchanger area and, therefore; a smaller, less expensive piece of equipment.The the greater the U, the better the performance.
Why Expansion bellows are required in heat exchanger?
expension belows are used for heat exchanger to avoid thermal stress
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.
What is the abbreviation for heat exchanger?
hx
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
