Principles of Air Distribution Systems

Air distribution systems are responsible for delivering conditioned air from the HVAC equipment to the occupied spaces within a building. The design of these systems significantly impacts the efficiency and effectiveness of the HVAC system. Two primary types of air distribution methods are commonly employed:​

1. Mixing (Dilution) Systems: These systems supply air at high velocity, promoting thorough mixing of supply air with room air. This approach ensures uniform temperature and contaminant concentration throughout the space. Ceiling-mounted diffusers are typically used to achieve this mixing effect. ​
   
   

2. Displacement Ventilation Systems: In contrast, displacement systems introduce air at low velocities near the floor level. The cool air spreads across the floor and rises naturally as it encounters heat sources, such as occupants or equipment. This method creates a stratified environment, with cooler, cleaner air in the occupied zone and warmer, contaminated air above, which is then exhausted. ​
   
   

Standards and Guidelines

Adherence to established standards is crucial in HVAC ventilation design to ensure system performance, safety, and indoor air quality. The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) provides comprehensive guidelines and standards that serve as benchmarks for the industry. Key publications include:

• ASHRAE Handbook: This four-volume resource covers fundamentals, refrigeration, HVAC applications, and HVAC systems and equipment, offering detailed information on design principles and best practices. ​
  
  

• ASHRAE Standard 62.1: Titled "Ventilation for Acceptable Indoor Air Quality," this standard specifies minimum ventilation rates and other measures to ensure indoor air quality in commercial and institutional buildings. ​
  
  

Compliance with these standards is essential for designing effective air distribution systems that meet regulatory requirements and promote occupant well-being.​
