@refrigerationmentor: Do you know what makes a CO₂ system transcritical and why it works differently than traditional systems? Share your thoughts in the comments. This video breaks down the full CO₂ refrigeration process, showing how refrigerant moves through compression, gas cooling, pressure control, and heat absorption. Understanding what happens above the critical point is essential for working on modern supermarket systems. • Low pressure vapor compressed to high pressure vapor • No liquid or vapor phase above the critical point • Gas cooler heat rejection through temperature drop only • Flash tank separation and bypass control • Medium and low temperature load operation Strong fundamentals lead to faster troubleshooting and better system performance. 👉 Follow us and explore the Refrigeration Mentor community through the link in our bio to learn from technical specialists supporting technicians worldwide. #RefrigerationMentor #refrigeration #co2 #gonatrefs #hvacr #commercialrefrigeration #supermarketrefrigeration
