Refrigeration & Air Conditioning Workshop
About the Refrigeration & Air Conditioning Workshop
The Refrigeration & Air Conditioning Workshop is a fully practical, hands-on training
designed to teach participants how cooling systems are assembled, charged, tested, and serviced.
This workshop is ideal for engineering students, HVAC beginners, technicians, makers, and anyone
interested in learning how refrigeration and air conditioning systems work.
By the end of the workshop, every participant will assemble, connect, vacuum-test, and operate a
functioning refrigeration/AC system while gaining a strong understanding of the complete cooling cycle.
🧩 Workshop Modules – Refrigeration & AC Workshop
📘 HVAC Theory & Refrigeration Cycle
Learn the complete vapour compression cycle, thermodynamics of cooling, superheating, subcooling, pressure–temperature relationships, compressor operation, refrigerant flow, and system efficiency principles. All concepts are explained in simple, practical ways.
🔧 System Assembly & Component Integration
Hands-on assembly of compressor, condenser, evaporator, capillary/expansion valve, copper tubing, filters, and electrical components. Learn pipe flaring, brazing basics, insulation, and system layout for real HVAC units.
🧪 Vacuuming, Leak Testing & Refrigerant Charging
Perform vacuum creation, deep vacuum checks, nitrogen leak testing, gauge reading, refrigerant charging (R134a / R22 / R290 depending on model), and system performance verification using pressure and temperature parameters.
❄️ System Operation & Cooling Performance Test
Start and operate the assembled HVAC system, measure cooling efficiency, identify frost formation behaviour, diagnose low/high pressure issues, and perform practical troubleshooting of real-world refrigeration problems.
⏳ Workshop Duration
The workshop is conducted over 3 to 5 days depending on the module depth:
Day-1: HVAC theory + cycle understanding
Day-2: Component study + assembly
Day-3: Vacuuming + leak testing + charging
Day-4: Operation test + troubleshooting
