Air Conditioning & Refrigeration Fundamentals

11 week night school  (4 nights/week)

Program Objective: The training program is designed to teach incoming students both a comprehensive understanding of the fundamentals of air conditioning and refrigeration concepts and the practical hands-on mechanical skills as found in the trade.

Program Outline - Major Topics:

• Refrigeration cycle: vapor recompression system, heat transfer, pressure temperature concepts and measurements, gas laws.
 
• Refrigeration components: compressors, evaporators, condensers, metering devices dryers, accessories, controls.
 
• Refrigeration piping: cutting, bending, reaming, brazing, swaging, threading, sizing, oil trapping, leak testing, design of systems
 
• Refrigeration testing and operation: system design, evacuation, charging, sub-cooling, super heats, DTs, controls and adjustments, head pressure control, defrosting methods, troubleshooting
 
• Electrical: Ohms law, VOM meters, amp meters, transformers, solenoids, 1 ph and 3 ph motors, contractors, wiring, controls, low and high voltage, safety, thermostats, troubleshooting
 
• Air Conditioning: controls, system design, installation, wiring of systems, troubleshooting

Major Lab Activities: HANDS-ON TRAINING

• Compressors, tear down, assembly, failure analysis
• Electrical wiring of systems, troubleshooting components, hop-scotching
• Evaporator, condensers, metering devices
• Assembly of small commercial trainers, pressure testing, evacuation, charging techniques piping operations (including high temperature brazing)
• Electrical and controls wiring commercial trainer, using at least 16 different wiring diagrams.
• Refrigerant recovery on systems

Hands-On Training: The student learns proper function, troubleshooting and repairs in our lab by working on air conditioning and refrigeration equipment. Some of the equipment that the student will use:

Compressors: open, semi-hermetic and hermetic

Evaporators: static, blower

Condensers: air and water cooled

Metering devices: TEVs, AEVs, cap tubes

Refrigeration accessories

Piping operations-brazing, bending, flaring, swaging

Specialty tools usage: vacuum pumps, torches, amp probes, megohm meters, temperature test equipment, manifold gauges,

Graduation Requirements

1) Comprehension and working knowledge of the refrigeration cycle, components, controls, and operation.

2) Proper use of specialized refrigeration tools and testing equipment.

3) Working knowledge of electricity, wiring diagrams, control systems.

4) Ability to fabricate copper pipe and tubing runs, connections, flare fittings, swaging, bending and high temperature brazing in a professional tradesman like manner, with no leaks at 360 lbs. pressure.

5) Completion of 175 field exercises using state of the art HVACR testing methods.

Certification of Completion: Upon completing the above tasks and demonstrating proficiency in understanding air Conditioning and refrigeration systems and controls, a CERTIFICATION OF COMPLETION will be awarded .

Small Classes: Limited to 24 students with excellent instructor/student interaction.
