Question

state and explain the principle of condenser.​

Answer 1

Answer:

In systems involving heat transfer, a condenser is a device or unit used to condense a substance from its gaseous to its liquid state, by cooling it. In so doing, the latent heat is given up by the substance and transferred to the surrounding environment. Condensers can be made according to numerous designs, and come in many sizes ranging from rather small (hand-held) to very large (industrial-scale units used in plant processes). For example, a refrigerator uses a condenser to get rid of heat extracted from the interior of the unit to the outside air. Condensers are used in air conditioning, industrial chemical processes such as distillation, steam power plants and other heat-exchange systems. Use of cooling water or surrounding air as the coolant is common in many condensers.

Answer 2

Condenser:

• It is a heat transfer device that moves heat from a working fluid to a secondary fluid or the atmosphere.  
• The condenser makes use of the efficient heat transfer that occurs during phase transitions during the condensation of vapour into a liquid.  
• In most cases, the temperature of the vapour entering the condenser is higher than the temperature of the secondary fluid.  
• As it cools, it reaches saturation, condenses into a liquid, and releases a tremendous amount of heat.  
• As the process advances, the vapour amount decreases and the liquid amount increases.
• At the condenser's outlet, only liquid remains.
• The condensed liquid then cooled below saturation temperature in some condensers designed by adding extra length.
