Refrigeration Trainer

Training aid only

Refrigeration Trainer is a simplified simulation for learning how the parts of air conditioning and refrigeration systems work alone and together. It is not a charging chart, a design tool, or a substitute for training, the manufacturer's instructions or your local code.

• Numbers are typical values (3-ton R-410A split system and heat pump; R-404A walk-in cooler and freezer) and the physics is simplified. Always charge and diagnose from the unit's own data plate and charging chart.
• Handling refrigerant in the US requires EPA Section 608 certification. R-404A is being phased down; new walk-ins often use R-448A or R-449A with similar pressures. Never vent refrigerant, and never bypass a pressure switch or overload on real equipment.
• The compressor failure scenarios are sped up to show why each safety matters.
