VAV systems: what makes them succeed? What makes them fail?.

Author(s) : CAPPELLIN T. E.

Summary

When variable-air-volume (VAV) systems work right, they provide excellent temperature and humidity control and in addition deliver outside air to conditioned spaces in amounts sufficient to satisfy ASHRAE Standard 62 and meet all criteria required for acceptable indoor air quality. The final benefit is lower utility cost when compared to a comparable constant-air-volume system. However, the successful performance of VAV systems is often compromised by flawed conception, faulty design, defective installation, poor start-up, inaccurate operation, and inadequate maintenance. The paper is written from the viewpoint of a former contractor who is now a professional engineer and who has designed, installed, started, and maintained VAV systems.
