HVAC DDC System Design

This practical course covering Heating, Ventilating and Air Conditioning (HVAC) and Direct Digital Control (DDC) system design provides a simple approach for the design of HVAC DDC systems and enables students to understand and design various types of control solutions. The course emphasizes the latest available technology, critical “Do’s and Don’ts”, and accepted rule-of-thumb checks in the design of HVAC controls.
Broken into the following major categories, this course provides a methodical approach to DDC system design:  1) Hybrid Control and DDC; 2) Electric Control and DDC; 3) Control Valves; 4) Control Dampers; 5) Electronic Sensors; 6) Practical Examples including Chilled Water System, Condenser Water, Hot Water System, and Air Handling Unit Control; and 7) HVAC DDC Specifications. An optional field trip is included.
