The Floating Tube Coil Design Dramatically Reduces Tube Sheet Leaks FEATURE 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. In thermal power plants (T), the steam from the turbine exhaust flows into the ACC where condensation occurs Air-Cooled Condenser Sizing & Selection Posted on August 9, 2017 by icemeister Air-cooled condensers, often referred to as remote condensers, became more commonly used back in the 1960's and 1970's as the use of water-cooled systems which dumped city water down the drain became cost prohibitive or banned
. With construction savings of up to 25%, compared to a standard A-frame, construction time can be reduced by several months for large power plants Air-cooled condenser design fundamentals. The direct dry cooling option condenses turbine exhaust steam inside finned tubes, which are externally cooled by ambient air instead of sea or river. A. Chiasson, in Geothermal Power Generation, 2016 15.4.1 General. In air-cooled condensers, condenser heat is rejected directly to the ambient air.Thus, the condensing temperature is a function of the ambient air dry-bulb temperature. The obvious advantage of air-cooled condensers relative to water-cooled condensers is that cooling water is not needed cooled or evaporative-cooled condenser with an air-cooled condenser, note that the original design saturated condensing temperature (SCT) for those systems typically would be 105°F, so select your TD accordingly. Determining Condenser Capacity Requirement: The capacity of an air-cooled condenser is based on Total Heat o The air velocity recommended for air cooled condenser design at standard noise levels is around 3.0-4.0 m/s. In environments where lower noise levels are desired, the air velocity will also be reduced. Air velocities below this figure require the selection of a large heat exchanger. Higher air velocities, on the other hand require stronger an

Dry Bulb temperature: The design of an air-cooled condenser is primarily based on dry bulb temperature at the plant location.
Air cooled condensers should be located in secure areas where service is easily accessible. Areas where public access is available should be avoided. Avoid areas that contribute to ice and snow accumulation. Condensers should be located in clean areas free from debris or foreign mat-ter that could block the coil surface In evaporative condensers, both air and water are used to extract heat from the condensing refrigerant. In these condensers, the water is sprayed from top part on a bank of tubes carrying the refrigerant and air is induced upwards. There is a thin water film around the condenser tubes from which evaporative cooling takes place

The advantage of choosing an air-cooled system is that they: Are typically lower in initial purchase cost. Though there is a fair debate about this, it is typically true that the initial cost of air-cooled condenser and chiller systems are slightly lower. However, water-cooled systems might win out in longevity. Require less overall maintenance Air cooled condensers are used in power stations to condense waste steam after the steam turbine. The heat is dissipated to the ambient air by convection. This is a closed cooling circuit. The steam circulates through a heat exchanger which is cooled by the air flowing round it. The accumulated condensate is collected and re-used in the power. via outdoor air being drawn through the condenser coils. For a water cooled chiller, the refrigerant gives up its heat to a second water loop commonly referred to as the condenser water loop.

PROCESS DESIGN OF AIR COOLED HEAT EXCHANGERS (AIR COOLERS) (PROJECT STANDARDS AND SPECIFICATIONS) Page 4 of 19 Rev: 01 April 2011 3. Where expensive or insufficient water supplies are encountered or where cooling water pumping or treating costs are excessive, it is often found that air-cooled units are desirable for several services. The. cooled condensers use fans to facilitate cooling by the ambient air. Water-cooled condensers typically use an evaporative cooling tower. After the water has been chilled, it is distributed via pumps, pipes, and valves (the distribution system) to the loads, where a heat exchanger—for example, a cooling coil in an air-handler—transfers heat.
Condenser systems need either circulating water pumps to supply them with cooling water or fans to supply fresh air to air-cooled tubes. (Because most air-cooled condensers are relatively new. the air cooled condenser (7) of comparable capacity.
