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

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.

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.
