HVAC Parts & ControlsHVAC is an acronym that stands for heating ventilating and cooling. HVAC is sometimes referred to as "climate control" and is particularly important in the design of medium to large industrial and office buildings. The primary function of HVAC systems is to provide healthy and comfortable interior conditions for occupants.What HVAC components can be controlled (DDC) in a typical building? AHU (Air Handling Unit), rooftop package unit, VAV (Variable Air Volume) boxes, dampers, hot water coil, pumps, boilers, mixing valves, air wash, chiller, cooling tower, relief air fans, exhaust fans, VFD’s (Variable Frequency Drive), heat pumps, radiant heating, lighting controls, card access & fire alarm.Here is a small list of manufactures of HVAC controls equipment: AlertonBACtalk Ibex VAV-DD VAV-DD7 VAV-SD VAV-SDA VAV-SD2A VAVi-SD VLC-550 VLC-651R VLC-660R VLC-853 VLC-1188 VLC-1600 VLC-16160 VLC-16160IC3 T7350AscoControl valvesCarrierOne 3V i-Vu CCN CCNWeb com...
