HAC 231 - Circuits and Controls for HVAC 2
3 Lecture Hours
Prerequisites: HAC 221 or departmental approval
Green building performance is related to energy usage. HVAC circuits and controls contribute to the efficient use of energy. Students begin this course by exploring generic electronic devices before gaining further understanding of electronic analog and digital circuits. The course concludes with an analysis of direct digital control (DDC) systems as they relate to the use of energy to achieve comfort.
Upon successful completion of the course, the student will:
- Differentiate the generic devices used for electronic control systems.
- Identify DDC system components like analog input/output, digital input/output, CPU memory, automated building systems (ABS) protocols, topologies and architectures.
- Analyze wireless systems based on current communication standards.
- Demonstrate an understanding of variable frequency drives (VFD) and their operation to control fans by connecting the wiring to an existing VFD system or tracing a pictorial diagram from a manufacturer schematic.
- Generic electronic devices
- Invensys analog control schemes
- Honeywell analog and digital control schemes
- DDC systems
- BacNet network protocol
- Lonworks network protocol
Instructor approved online learning management system, internet access and specified Personal protective equipment (PPE)
