Cooling coils are heat exchanger components, typically made of copper tubes with aluminum fins, that remove heat from air in HVAC systems, reducing its temperature and often lowering humidity (dehumidification). They work by circulating cold refrigerant (Direct Expansion) or chilled water through the coils, allowing warm air to pass over them.
1. Direct Expansion (DX) Coils: Use refrigerant directly to cool the air, commonly found in split systems/ CSU/FCU.
2. Chilled Water Coils: Utilize cold water supplied by a chiller to cool the air, Commonly found in AHU. These components are essential for maintaining indoor air quality, managing humidity, and providing necessary cooling in residential and commercial environments.
