The Refrigeration Cycle Trainer demonstrates the complete refrigeration cycle, allowing students to visualize each stage — compression, condensation, expansion, and evaporation. Equipped with pressure gauges, thermometers, and observation points, it provides real-time performance data. Ideal for engineering colleges, polytechnic institutes, and ITIs, the trainer helps students understand heat transfer, energy efficiency, and system components. Its durable and portable design ensures repeated academic use. This trainer bridges theoretical and practical learning, making it an essential part of HVAC and refrigeration laboratories focused on skill-based education and technical training.
