Research Project: Energy Efficiency of Natural Refrigerants For Transport Refrigeration 2010

Research Project: Energy Efficiency of Natural Refrigerants For Transport Refrigeration

Current Results:
• Comparison of natural refrigerants CO2, propene and propane with R410A
• CO2, single-stage, ruled out due to high energy consumption
• To date, no efficient 2-stage CO2 refrigeration compressors available
• To date, highest efficiency with propene and 2-stage economizer circuit
• Propene with the best environmental properties of all natural refrigerants
• TÜV-tested safety concept for FRIGOBLOCK inverter controlled technology
