HVAC system types

 Here are the common types of HVAC (Heating, Ventilation, and Air Conditioning) systems:

1. Constant Volume (CV) System: 

Provides a constant airflow rate, regardless of temperature changes.

2. Variable Air Volume (VAV) System: 

Adjusts airflow rates based on temperature changes, for energy efficiency.

3. Constant Air Volume (CAV) System: 

Similar to CV, but with a fixed airflow rate and variable temperature.

4. Hybrid System: 

Combines different HVAC systems, such as gas and electric, for optimal performance.

5. Central Air Conditioning System: 

Uses a central unit to cool and distribute air throughout the building.

6. Decentralized Air Conditioning System: Employs multiple smaller units for cooling and heating.

7. Heat Pump System: 

Reverses refrigeration cycles for both heating and cooling.

8. Radiant Cooling System: 

Uses cooled surfaces for heat transfer, rather than air.

9. Displacement Ventilation System: Introduces fresh air at floor level, pushing stale air upwards.

10. Underfloor Air Distribution (UFAD) System: 

Uses underfloor space for air distribution.

11. Chilled Beam System: 

Employs cooled air and water for efficient cooling.

12. Packaged System: 

Self-contained units, like rooftop units, containing all HVAC components.

13. Split System: 

Separates heating and cooling components, often for zoning control.

14. Zone Control System: 

Divides buildings into separate temperature zones for efficient heating and cooling.

These HVAC system types cater to various building types, sizes, and applications, each with unique benefits and considerations.
