SMACNA HVAC SYSTEMS APPLICATIONS

Abstract

<strong>HVAC SYSTEM PURPOSE</strong> <br>The purpose of an HVAC system is to provide a suitable thermal environment in a defined space that meets the needs of the occupants and the activity that takes place in the space. Most HVAC systems are installed to establish an indoor environment within which building occupants can live, work, and play. The indoor environment impacts the quality of life, productivity, and well being of building occupants. As people spend an increasing amount of time inside buildings HVAC systems and their associated control systems are becoming more important. To address this growing need this manual focuses on HVAC equipment that creates human comfort indoors. Energy use in buildings is becoming increasingly important and impacting the type of the HVAC distribution system design, the HVAC equipment specified, and how the HVAC operates. HVAC systems are also required to provide suitable environmental conditions in addition to providing human comfort. In addition, energy use in buildings is becoming increasingly important and impacting the type of the HVAC distribution system design, the HVAC equipment specified, and how the HVAC operates. HVAC systems are also required to provide suitable environmental conditions for purposes other than human comfort.
