REFRIGERATION AND AIR CONDITIONING TECHNICIAN Learning Outcomes
The Refrigeration and Air Conditioning Technician trade under the Craftsmen Training Scheme (CTS) focuses on developing technical competencies required for working in refrigeration and HVAC industries. Learning outcomes represent the knowledge, practical skills, and professional abilities that trainees are expected to achieve after completing the training program. These outcomes ensure that trainees are capable of performing installation, maintenance, troubleshooting, and servicing of refrigeration and air conditioning systems in real industrial environments. :contentReference[oaicite:1]{index=1}
The learning outcomes for this trade are divided into two categories corresponding to the two years of training. Each outcome reflects the expected competency level that trainees must demonstrate through practical work and theoretical understanding.
First Year Learning Outcomes
During the first year, trainees develop foundational knowledge and skills related to workshop practices, electrical systems, electronics, and refrigeration equipment. The focus is on understanding basic principles and performing fundamental operations used in refrigeration and air conditioning systems.
Safety and Workshop Practices
Trainees learn to identify trade-related hazards and follow proper safety procedures while working in the workshop. They understand the importance of personal protective equipment (PPE), fire safety, and accident prevention techniques. Safety awareness is essential when handling electrical equipment, welding tools, and pressurized refrigerants.
Fitting and Sheet Metal Operations
Students gain skills in producing fitting jobs according to engineering drawings. They perform operations such as marking, sawing, filing, drilling, reaming, tapping, and threading. Sheet metal operations such as cutting, bending, riveting, and soldering are also practiced to prepare components used in refrigeration systems.
Electrical and Electronic Fundamentals
Another important learning outcome is the understanding of electrical safety and measurement techniques. Trainees learn to measure current, voltage, resistance, and power using measuring instruments. They also practice connecting single-phase and three-phase motors using star and delta connections.
Trainees also learn to identify electronic components such as transistors, capacitors, diodes, amplifiers, and integrated circuits. They practice soldering techniques and basic electronic circuit construction.
Welding and Brazing
Students learn to perform gas welding, brazing, and soldering operations used in refrigeration systems. These techniques are essential for joining metal components and copper tubes used in refrigeration pipelines.
Refrigeration Tools and Equipment
Trainees identify refrigeration tools and equipment and learn to recognize the various components of refrigeration systems. They perform operations such as copper tube cutting, bending, flaring, swaging, and brazing used in RAC systems.
Servicing Domestic Refrigeration Systems
First-year trainees learn to test mechanical and electrical components of refrigerators. They perform leak testing, evacuation, gas charging, and wiring during refrigerator installation and servicing.
They also identify electrical and mechanical components of refrigerators, diagnose faults, and perform basic repairs.
Compressor Maintenance
Students learn to dismantle, repair, and assemble hermetic compressors. They also learn to identify compressor terminals and measure current, voltage, and power consumption of motors used in refrigeration systems.
Air Conditioning Installation
Another learning outcome includes installation and servicing of window air conditioners and split air conditioning systems. Trainees learn wiring, fault diagnosis, leak testing, and gas charging procedures used in these systems.
Second Year Learning Outcomes
The second year focuses on advanced refrigeration and air conditioning systems used in commercial and industrial environments. Trainees gain expertise in servicing large refrigeration plants and HVAC systems.
Commercial Compressor Servicing
Students learn to dismantle and service different types of commercial compressors. They inspect worn-out components, replace defective parts, and check lubrication systems to ensure efficient compressor performance.
Cooling Systems and Condensers
Trainees learn to service water-cooled condensers, evaporative condensers, and cooling towers. They perform cleaning, descaling, and performance testing to ensure efficient heat transfer in cooling systems.
Refrigeration Equipment Maintenance
Students gain practical experience in servicing refrigeration equipment such as water coolers, bottle coolers, deep freezers, ice cube machines, and ice plants. They perform troubleshooting, gas charging, electrical testing, and maintenance procedures.
Cold Storage and Industrial Refrigeration
Another learning outcome is servicing of cold storage plants and walk-in coolers used in food preservation and industrial refrigeration applications. Trainees learn preventive maintenance techniques and performance monitoring methods used in these systems.
HVAC System Operation
Trainees study HVAC concepts such as psychrometric properties of air, airflow measurement, and ventilation systems. They learn to measure temperature, humidity, and airflow using instruments like psychrometers and anemometers.
They also learn to construct and install air ducts and insulation used in HVAC systems.
Central Air Conditioning Systems
Students gain knowledge about package air conditioners, central air conditioning plants, and VRF/VRV systems. They learn installation, servicing, troubleshooting, and performance evaluation of these systems.
Mobile Air Conditioning Systems
Another learning outcome includes servicing and maintenance of mobile air conditioning systems used in vehicles such as buses and trains. Trainees learn to check refrigerant levels, repair compressors, and diagnose system faults.
Preventive Maintenance and Documentation
Trainees learn preventive maintenance procedures for refrigeration and air conditioning systems. They also maintain log books and operational records to monitor equipment performance and maintenance history.
Engineering Drawing and Basic Science
Throughout the training program, trainees develop the ability to read and interpret engineering drawings used in installation and maintenance work. They also apply mathematical concepts and scientific principles related to refrigeration technology.
Conclusion
The learning outcomes of the Refrigeration and Air Conditioning Technician course ensure that trainees acquire comprehensive knowledge and practical skills required in modern refrigeration and HVAC industries. Through structured training and hands-on experience, trainees become capable of installing, servicing, troubleshooting, and maintaining refrigeration and air conditioning systems.
These competencies prepare trainees for employment in domestic, commercial, and industrial sectors where refrigeration and air conditioning systems play a crucial role in maintaining temperature-controlled environments.
