HVAC System
The integrated system of equipment, controls, and distribution networks that provide heating, ventilation, and air conditioning.
Full Definition
An HVAC System is the integrated collection of equipment, controls, and distribution networks (ductwork, piping) that work together to provide heating, ventilation, and air conditioning to a building. HVAC systems include central plants (chillers, boilers, cooling towers), air handling units, terminal units (fan coils, VAV boxes), distribution systems (chilled water, hot water, steam, air), and controls. Systems can be organized by type (chilled water system, air system) or by zone.
