HVAC Equipment Selection - Key Components & Applications
1. AHU (Air Handling Unit)
Function: Conditions and distributes air
Use: Large buildings
Cooling/Heating: Chilled/hot water or DX coil
Location: Centralized (mechanical rooms)
2. FCU (Fan Coil Unit)
Function: Heats/cools air in small spaces
Use: Individual rooms or zones
Cooling/Heating: Chilled/hot water
Location: Decentralized (inside rooms)
3. VAV (Variable Air Volume)
Function: Controls airflow volume to zones
Use: Zoned air distribution
Cooling/Heating: Works with AHUs
Location: In ductwork near zones
4. VRF (Variable Refrigerant Flow)
Function: Provides heating/cooling via refrigerant
Use: Energy-efficient for multi-zone buildings
Cooling/Heating: Direct refrigerant (no chilled
water)
Location: Outdoor unit with multiple indoor units
5. Chillers
Function: Produces chilled water for cooling
Use: Large HVAC systems
Cooling/Heating: Supplies chilled water to AHUS/
FCUs
