Air Cooled Condenser

We are United Heat Exchanger providing solution for Air condensation system for all types of Thermal Power plants.In systems involving heat transfer, a condenser ( Air Cooled Condenser )is a device or unit used to condense a substance from its gaseous to its liquid state, typically by cooling it. In so doing, the latent heat is given up by the substance, and will transfer to the condenser coolant. Condensers are typically heat exchangers which have various 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.

 

Specifications :

  • A condenser unit used in central air conditioning systems typically has a heat exchanger section to cool down and condense incoming refrigerant vapor into liquid, a compressor to raise the pressure of the refrigerant and move it along,
  • A fan for blowing outside air through the heat exchanger section to cool the refrigerant inside.

Applications :

  • A typical configuration of such a condenser unit is as follows: The heat exchanger section wraps around the sides of the unit with the compressor inside.
  • In this heat exchanger section, the refrigerant goes through multiple tube passes, which are surrounded by heat transfer fins through which cooling air can move from outside to inside the unit.

Advantages :

  • There is a motorized fan inside the condenser unit near the top, which is covered by some grating to keep any objects from accidentally falling inside on the fan.
  • The fan is used to blow the outside cooling air in through the heat exchange section at the sides and out the top through the grating.
  • These condenser units are located on the outside of the building they are trying to cool, with tubing between the unit and building, one for vapor refrigerant entering and another for liquid refrigerant leaving the unit.
  • Of course, an electric power supply is needed for the compressor and fan inside the unit.

air cooled heat exchanger

Air-cooled heat exchangers are generally used where a process system generates heat which must be removed, but for which there is no local use. A good example is the radiator in your car. The engine components must be cooled to keep them from overheating due to friction and the combustion process. The excess heat is carried away by the water/glycol coolant mixture. A small amount of the excess heat may be used by the car’s radiator to heat the interior. Most of the heat must be dissipated somehow. One of the simplest ways is to use the ambient air. Air-cooled heat exchangers (often simply called air-coolers) do not require any cooling water from a cooling tower. They are usually used when the outlet temperature is more than about 20 deg. F above the maximum expected ambient air temperature. They can be used with closer approach temperatures, but often become expensive compared to a combination of a cooling tower and a water-cooled exchanger.

Typically, an air-cooled exchanger for process use consists of a finned-tube bundle with rectangular box headers on both ends of the tubes. Cooling air is provided by one or more fans. Usually, the air blows upwards through a horizontal tube bundle. The fans can be either forced or induced draft, depending on whether the air is pushed or pulled through the tube bundle. The space between the fan(s) and the tube bundle is enclosed by a plenum chamber which directs the air. The whole assembly is usually mounted on legs or a piperack.

 

The fans are usually driven be electric motors through some type of speed reducer. The speed reducers are usually either V-belts, HTD drives, or right angle gears. The fan drive assembly is supported by a steel mechanical drive support system. They usually include a vibration switch on each fan to automatically shut down a fan which has become imbalanced for some reason

 

The air-cooled heat exchangers are mostly used when the plant location and the ambient conditions do not allow an easy and economic use of other cooling systems.

 

Specifications :

  • Lower environmental impact than shell and tube heat exchangers thanks to the elimination of an auxiliary water supply

Applications :

  • Reduction of maintenance costs
  • No problem arising from thermal and chemical pollution of cooling fluids

Advantages :

  • Easy installation by bolted assembly
  • Flexibility for any plant location and plot plan arrangement(installation over other units)

shell and tube heat exchanger

Shell and Tube Heat Exchanger is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. Shell Tubes Heat Exchanger are classified into fixed and Floating type Heat Exchangers . Fixed type Heat Exchangers are used where there are absolutely no chances for inter mixing of two fluids.

Vertical Shell and Tube Heat Exchanger

Shell and tube heat exchangers consist of a series of tubes. One set of these tubes contains the fluid that must be either heated or cooled. The second fluid runs over the tubes that are being heated or cooled so that it can either provide the heat or absorb the heat required.

In this type, the tube sheets are completely welded to the shell and acted as shell flanges. The Floating type Heat Exchangers has the advantages of removability of tube bundle and access for cleaning both inner and outer side of tubes and shell.

 

Specifications

  • Shell Tube Heat Exchanger stream a process fluid and other cooling water or air.
  • This is an efficient way to conserve energy.
  • Two-phase heat exchangers can be used to heat a liquid to boil it into a gas

Applications :

Shell Tube Heat Exchanger is widely used in variety of application as a cooling solution. The most common amoung them is for cooling of Hydraulic Fluid and oil in engines, transmissions and hydraulic power packs. With the right coimbination of materials they can also be used to cool or heat other mediums, such as swimming pool water or charge air. One of the big advantages of using a shell and tube heat exchanger is that they are often easy to service, particularly with models where a floating tube bundle (where the tube plates are not welded to the outer shell) is available. Can also be used on fixed tube sheet heat exchangers

  • space heating
  • refrigeration
  • air conditioning
  • power plants
  • chemical plants
  • petrochemical plants
  • petroleum refineries
  • natural gas processing
  • sewage treatment

Advantages :

  • Shell Tube Heat Exchanger is often easy to service, particularly with models.
