This study introduces the design of a novel condenser for air conditioning systems. Enhancement of performance of the system was manifested by increasing the coe±cient of performance (COP), decreasing the pressure drop and the power consumed by the A Uniquely Finned Tube Heat Exchanger Design of a Condenser for Heavy-Duty Air Conditioning
A Literature Review On Heat Exchanger Air Side Fouling In Heating, Ventilation And Air- This paper provides a review on the fouling mechanism and its effect onto the performance of finned tube heat water for cooling of condensers, air-cooled condensers might be the only option. Due to extensive use of air cooled heat exchangers in HVAC Air-Cooled Heat Exchangers - an overview ScienceDirect Similarly, for relatively small air cooled heat exchangers, the air flow may be horizontal across vertical tube bundles. In order to improve the heat transfer characteristics of air cooled exchangers, the tubes are provided with external fins.
The economic profitability of an air-cooled heat exchanger depends on the capacity of the finned tubes. The capacity results from the transfer of the maximum heat exchanged in the smallest possible space while keeping thermodynamic losses on the air side low.

In a finned tube heat exchanger, heat is exchanged between a thermally efficient fluid that transports heat efficiently, such as a liquid which has some viscosity, and a fluid that does not, such as air or gas with little density. On the air side, the tube surface is enhanced by the addition of fins or other elements such as looped wires MANAGING CORROSION CHALLENGES ASSOCIATED Air Cooled Heat Exchanger Nozzle Tube spacer Tube Support (bottom) Tube Air Seal Header Lifting Lug Header Fins Tube Keeper Vent Drain Fixed Support Sliding Material:Carbon Steel (with Al Fin on the external) Number of Tubes:258 per bank Total No of Tubes:258 x 40 banks = 10,240 tubes Mode of Attack:
Apr 01, 2020 · The use of annular fins in air-cooled heat exchangers is a well-known solution, commonly used in air-conditioning and heat-recovery systems, for enhancing the air-side heat transfer. Although associated with additional material and manufacturing costs, custom-designed finned-tube heat exchangers can be cost-effective.

More generally, air conditioning can refer to any form of technological cooling, heating, ventilation, or disinfection that modifies the condition of air. Air Cooled Heat Exchangers is typically done using a simple refrigeration cycle, but sometimes evaporation is used, commonly for comfort cooling in buildings and motor vehicles.
