Quick Answer: What Is The Working Of Condenser?

What is condenser and how it works?

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.

The major types of condensers used are (1) water-cooled, (2) air-cooled, and (3) evaporative..

How many types of condensers are there?

three typesThere are three types of condensers: air cooled, water cooled and evaporative.

What are the three functions of a condenser?

Condensers. A condenser’s function is to allow high pressure and temperature refrigerant vapor to condense and eject heat. There are three main types: air-cooled, evaporative, and water-cooled condensers.

What is the importance of condenser?

In thermal power plants, the purpose of a surface condenser is to condense the exhaust steam from a steam turbine to obtain maximum efficiency, and also to convert the turbine exhaust steam into pure water (referred to as steam condensate) so that it may be reused in the steam generator or boiler as boiler feed water.

Which gas is used in chiller?

Different gases are used but the most commonly used one in the industry is HFC-134a Refrigerant , because it has got Zero Ozone Depletion Potential, it is environmentally safe.

Why condenser is used in fan?

Fan condenser is just used to create starting torque by increasing the current lead through the starting winding ,after started running of 1-phase motor we can remove capacitor even after removing the capacitor the motor will not stop and continous in running.

How vacuum is created?

Vacuum, space in which there is no matter or in which the pressure is so low that any particles in the space do not affect any processes being carried on there. … A vacuum can be created by removing air from a space using a vacuum pump or by reducing the pressure using a fast flow of fluid, as in Bernoulli’s principle.

Why vacuum is maintained in condenser?

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. … Therefore, vacuum is maintained in the condenser using either vacuum pump or steam ejector.

What is difference between condenser and compressor?

The main difference between the compressor and condenser is indicated by their names, respectively. In a nutshell, the compressor compresses and the condenser condenses. … Keep in mind, the refrigerant is a gas as it travels through the compressor – still a gas, yet slightly altered in order to be made into liquid vapor.

What goes in a condenser?

The refrigerant enters the condenser as a high-pressure vapor, but as it flows through the condenser and cools, it turns back into a cooler high-pressure liquid. … The condenser releases heat from the hot A/C system refrigerant passing through it, to the atmosphere.

Is capacitor and condenser are same?

Capacitors and condensers are components used in electric circuits, which can store charge. … So, the main difference between capacitor and condenser is that the term capacitor is a relatively newer term while condenser is an older term.

How does a surface condenser work?

A surface condenser is a commonly used term for a water-cooled shell and tube heat exchanger installed to condense exhaust steam from a steam turbine in thermal power stations. These condensers are heat exchangers which convert steam from its gaseous to its liquid state at a pressure below atmospheric pressure.

What is difference between evaporator and condenser?

While the evaporator coil picks up heat from indoor air, the condenser coil releases heat into outdoor air. The load of heat energy extracted from your home and compressed in hot refrigerant vapor is rapidly released when refrigerant circulates into the coil and condenses to liquid.

Why condenser is used in Rankine Cycle?

A condenser is used to convert the steam from the exit of the turbine to saturated liquid. This is done so that we can use a pump to pressurize the liquid. There is no mechanical device till date which can work on steam+liquid mixture. So we have to use a pump or a compressor to increase the pressure.

What is the function of condenser in refrigerator?

A refrigerator uses a condenser to get rid of heat extracted from the interior of the unit to the outside air. Condenser is a device or unit used to condense a substance from its superheated gas phase to its saturated or subcooled liquid state, by cooling it.

Why it is called surface condenser?

Condense the steam by indirect contact, with the cold surface of the tubes in a shell-and-tube condenser. Thus the term surface condenser. Simply by condensing thru cold surface and not by direct mixing of cold fluid.

What is the difference between jet 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.

How do you maintain a condenser vacuum?

The removal of air and other noncondensable gases from the condenser shell side is required for proper heat transfer from steam to cooling water in the condenser and, thus, to maintain high vacuum in the condenser.

What is back pressure in condenser?

High condenser back pressure is the most obvious plant measurable that results in lost revenue or excess operating costs. Turbine exhaust back pressure is directly related to lost power output to the generator that converts mechanical energy to electrical power.
