HVAC 212 - Advanced HVAC Controls
PREREQUISITES: HVAC 202 - Electrical Circuits & Controls
PROGRAM: Heating, Ventilation and Air Conditioning
CREDIT HOURS MIN: 3
LECTURE HOURS MIN: 2
LAB HOURS MIN: 2
DATE OF LAST REVISION: Spring, 2019
Covers control systems beyond ordinary residential and single zone commercial applications. Includes solid state controls, 0-10 volt DC and 4-20 milliamp control signals, zoning controls, modulating controls, low ambient controls, heat recovery and energy management controls, economizer controls, 3-phase motor protection modules, variable frequency drives [VFDs], remote sensing electronic thermostats, electronically commutated DC motor control, Direct Digital Control [DDC] systems, multiple-stage heating/cooling controls, PLC control of HVAC/R equipment and pneumatic controls.
MAJOR COURSE LEARNING OBJECTIVES: Upon successful completion of this course the student will be expected to:
- Demonstrate safe practices and procedures.
- Recognize and describe solid state controls such as solid state “demand” defrost controls, anti-short cycling devices, furnace integrated circuit boards [ICBs] and 3-phase motor protection monitors.
- Explain basic concepts associated with Direct Digital Control [DDC].
- Recognize and describe special controls used in economizers, heat reclaim and energy management systems.
- Recognize and describe pneumatic control systems such as those used for induction units and variable air volume units.
- Explain how variable frequency drives control motor speed.
- Explain the difference between 0-10 volt DC and 4-20 milliamp control signals.
- Outline the various methods of zoning covered in this course.
- Describe the use of PLCs in HVAC/R equipment control.
- Compare and contrast the various low ambient control systems covered in this course.
