This course covers the fundamentals of how heating, ventilation, and air conditioning (HVAC) systems are controlled and regulated. Here's a brief overview of what such a lecture might include:
Introduction to HVAC Controls
Purpose of Controls: Automatic controls are essential for maintaining stable and efficient operation of HVAC systems. They help manage variables like temperature, humidity, and air quality.
Types of HVAC Systems: Self-contained units (e.g., rooftop HVAC systems) and central systems (e.g., central chillers and boilers).
Basic Components of Control Circuits
Power Source: The electrical supply needed to power the control system.
Switches and Sensors: Devices that turn the system on and off or regulate its operation.
Actuators and Relays: Components that physically control the HVAC system (e.g., opening/closing valves).
Control Principles
Measurement and Data Collection: Sensors measure variables like temperature and humidity.
Data Processing: Controllers process the collected data to make decisions.
Control Actions: The system responds by adjusting actuators to maintain desired conditions.
Types of Control Systems
Two-Wire and Three-Wire Controllers: Different configurations for controlling actuators and relays.
Line Voltage and Low Voltage Controls: Systems that operate on different voltage levels.
Applications and Examples
Residential and Industrial HVAC Systems: How control circuits are used in different settings.
Special Applications: Examples like food storage, chemical processing, and vehicle air conditioning.
