What is Vapour condenser?
A heat-transfer device that reduces a thermodynamic fluid from its vapor phase to its liquid phase. The vapor condenser extracts the latent heat of vaporization from the vapor, as a higher-temperature heat source, by absorption in a heat-receiving fluid of lower temperature.
How does a vapor condenser work?
Most are designed to mount directly on a tank or reactor vent flange, with vapors rising up through the tubes, condensing, and the condensate dripping back down into the tank. This is achieved with coolant on the shell side, which cools the tube walls, causing condensation of the vapor.
What is the function of condenser?
The function of the condenser in a refrigeration system is to transfer heat from the refrigerant to another medium, such as air and/or water. By rejecting heat, the gaseous refrigerant condenses to liquid inside the condenser.
What is vacuum condenser?
The vacuum condenser is used to generate back-pressure for improving turbine performance and recollecting exhaust steam. It can be used to remember steam that was discharged from a tanker ship.
What is the purpose of using a condenser Mcq?
What is the purpose of using a condenser? Explanation: Condenser is used to convert vapor refrigerant discharging from the compressor into liquid refrigerant by rejecting or removing heat and attaining the saturated liquid line for the refrigerant.
How does an air cooled condenser work?
An air cooled condenser (ACC) is a direct dry cooling system where steam is condensed inside air-cooled finned tubes. The cool ambient air flow outside the finned tubes is what removes heat and defines the functionality of an ACC.
What is the advantage of condensing the steam?
The main advantages of incorporating a steam condenser in a steam power plant are as follows: It increases the efficiency of the power plant due to increased enthalpy drop. It reduces back pressure of the steam which results in more work output.
What is the price of AC condenser?

|MarQ FKAC103SIAINC 1.5 Ton 3 Star Inverter Split AC||Rs.22,999|
Which type of condenser is the most efficient?
Water-cooled systems are more efficient for heat transfer than air-cooled systems because air-cooled systems are limited by the dry bulb temperature, resulting in higher condensing temperatures and therefore lower chiller efficiency.
How does a glass condenser work?
A typical condenser consists of a glass tube nested within another. Water flows between these two tubes. A chemist attaches the condenser to the top of a flask so that as refluxing solvent evaporates and travels up through the center tube, the flowing water cools the solvent.
How does a condenser operate?
All condensers operate by removing heat from the gas or vapour; once sufficient heat is eliminated, liquefaction occurs. For some applications, all that is necessary is to pass the gas through a long tube (usually arranged in a coil or other compact shape) to permit heat to escape into the surrounding air.
Why is it important to keep the main condenser in vacuum?
Now to ensure proper and continuous flow of steam to condensers at all times, vacuum must be maintained externally. … A vacuum is maintained in the condenser so that steam can easily flow and more work can be extracted from the steam in the turbine; this is the reason why vacuum is maintained in condensers.
How do I improve my condenser vacuum?
10 Tips to Ensure Reliable Vacuum Condenser Performance
- TIP 1: Conservatively Estimate Noncondensible Loading. …
- TIP 2: Understand Vapor-Liquid Equilibrium of the Vapor Components in Your Process. …
- TIP 3: Properly Elevate a Vapor Condenser. …
- TIP 4: Define the Range of Cooling Water Temperature and Flow Rate.
What happens when a condenser loses its vacuum?
A common cause of poor condenser vacuum is excessive air ingress or leakage. Any fall in condenser vacuum would have consequent rise in turbine heat rate vis–vis plant heat rate. As a result, cost of power generation would increase with eventual loss in revenue earning.
In which condenser requires high maintenance cost?
Disadvantages: Capital cost and maintenance cost are high. Jet condenser is bulky compared to the jet condenser.
Which turbine has highest speed?
Which turbine has highest speed? Explanation: Francis turbine has a specific speed of 60 to 300 rpm.
Why both reheating and regeneration is used together?
Explanation: When vaporization pressure is high, the reheating of steam is adopted. 2. Why both reheating and regeneration is used together? Explanation: Thus a modern steam power plant has both reheating and regeneration.
What are some disadvantages of an air cooled condenser?
Disadvantages of air cooled condensers:
- Air cooled condensers required more power to run.
- It is not suitable for long duration period.
- The cooling effect is not so high.
- It does not supply the required cooling in a short time.
What are the three types of water-cooled condensers?
Commercial water-cooled condensers are of three basic types: shell-and-coil tube-within-a-tube, or double-tube shell-and-tube multi-pass. The shell condenser, or shell-and-coil condenser as it is commonly called, is a tank made of steel with copper tubes inserted in the shell.
Why air cooler section is provided in a condenser?
10.2. 2 The condenser air cooling section This ensures that the air cooling process is achieved with minimum pressure loss through the condenser, and without creating stagnation regions within the main condensing zone or introducing excessive steam penetration into the air cooling section.
What is the difference between condenser and surface condenser?
Surface condensers (or non-mixing type condensers). In surface condensers, there is no direct contact between the exhaust steam and the cooling water. … In jet condensers there is direct contact between the exhaust steam and cooling water.
What gives the input steam for condenser?
These condensers are heat exchangers which convert steam from its gaseous to its liquid state, also known as phase transition. … In so doing, the latent heat of steam is given out inside the condenser.
What are the elements of condensing plant?
Elements or Components of Condensing Plant:
- Air Extraction Pump.
- Condensate Extraction Pump.
- Cooling Water Circulating Pump.
- Hot Well.
- Cooling Tower.
- Boiler Feed Pump.
- Makeup Water Pump.
How do you fix a leaking AC condenser?
Can Aluminium condenser be repaired?
Aluminum refrigerator coils, lines and other components can be repaired quickly and permanently using tungsten-inert-gas (TIG) welding, as it is popularly known.
How do you clean AC condenser?
How to Clean Condenser Coils
- Turn the thermostat and main power switch off.
- Visually inspect the unit for damage. …
- Remove leaves and debris from the outside of the unit.
- Use a cooling fin comb to straighten any bent fins.
- Remove the top of the unit, carefully. …
- Vacuum dirt and debris out of the bottom of the unit.
What are the three functions of a condenser?
There are three very important functions the condenser performs in keeping your air conditioner performing its best. These include rejecting superheated refrigerant gas, condensation, and subcooling refrigerant once it is transformed back into a liquid state.
How do I choose a condenser?
The principal factors involved in selecting a suitable type of condenser depends on whether condensation is total or partial, whether the vapors are single or multicomponent, and whether some components are noncondensable. The coolant can impose further restrictions, particularly if it vaporizes.
Which type of condenser is best for AC?
Copper condensers, with grooved copper tubes/coil, epoxy (bluefin/goldfin/ocean black) coating, and inverter dual compressor make the best combination for your AC. Not only will it be durable and efficient, but also easy to clean and will cost less for maintenance.
