The Standards for Air Cooled Condensers (ACCs) covers specification and design recommendations, along with performance and operational issues associated with air cooled condensers for power plant applications. The standard includes typical purchaser requirements and manufacturers’ experience. It also highlights the important design criteria for air cooled condensers.
V-II 230V/3-phase, zoned variable refrigerant flow (VRF) systems offer large capacity and operational efficiencies up to 24.30 IEER to Air-Conditioning, Heating, and Refrigeration Institute (AHRI) 1230 standard and are ideal heating/cooling solutions for small and large buildings.
Designed with California Title 24 regulatory compliance in mind, these condensers are available with one to 14 fans and single- and double-fan-width models in either vertical or horizontal airflow configurations.
The condenser is the component that rejects the heat from the system. Most equipment is air cooled and rejects heat to the air. The coils are copper or aluminum and both types have aluminum fins to add to the heat exchange surface area.
Some years ago it was common for air-cooled condensers to develop leaks, resulting in unpredictable shorter service life. By studying the causes, it’s possible to come up with solutions. It became obvious that vibration was the major culprit, and thermal expansion/contraction creates some specific problems where the hot gas first enters the coil.
