  • VAV - Variable Air Volume - the temperature of the supply air remains constant, but the air volume varies 
  • CAV - Constant Air Volume - the volume of air supply remains constant, but the temperature varies

Constant Air Volume - CAV - systems are becoming less common in new buildings since VAV systems provides closer control of air temperature and requires lower fan speeds, resulting in less energy consumption and less noise.
