Didier Coulomb - IIR - SOSTENIBILITA’ DEL TRASPORTO REFRIGERATO SU STRADA
Refrigerated transport via trucks is essential for delivering perishable goods but faces challenges around reducing energy consumption and handling refrigerants with high global warming potential. Solutions proposed include improving vehicle aerodynamics and insulation, optimizing refrigeration systems, and transitioning to natural refrigerants. While solutions vary between refrigerated transport, mobile air conditioning, and other sectors, all need strategies to lower both energy usage and high-GWP refrigerant emissions over time.

- 2. Refrigerated Trucks Refrigerated transportis an essential link in the cold chain. It aims to supply the consumer with safe and high-quality perishable goods. Global road freight transport is expected to grow 2,5% per year until 2030. Temperature-controlled pharmaceutical freight is expected to grow more than 20% per year. Needs for food will also dramatically increase in developing countries, which have to build a real cold chain (cf my introduction) We need to reduce the vehicle’s energy consumption and to handle the refrigerants issue, especially in Europe.

- 4. Refrigerant Issues The vastmajority of refrigerated vehicles currently use HFCs with high Global Warming Potentials (GWP) as refrigerants. The leakage rate in refrigerated transport could be as high as 25%/annum. Even if the global consumption of HFCs in refrigerated vehicles is limited (about 2% according to UNEP), there will be measures to reduce it, particularly in Europe, with the future extension of the F-gas Regulation in this sector.

- 5. Solutions (apart frombetter control): Reducing the refrigerant charge Using lower GWP HFCs Using natural refrigerants: CO2, NH3, Hydrocarbons Alternative production systems: cryogenic systems, sorption systems, hybrid systems, Phase-Change Materials (PCMs)… Moving to other systems with less or no high GWP refrigerant emissions will be done later than in other sectors. Solutions are similar, but must be adapted; they are more or less promising than in other sectors. For instance, more than 1000 vehicles equipped with cryogenic systems are already in service in Germany and France (2009), particularly because of different constraints (noise in urban areas…) For more information: consult the IIR Informatory Note « Sustainable Refrigerated Road Transport » (December 2011) http://www.iifiir.org/userfiles/file/publications/notes/NoteTech_21_EN.pdf XV EUROPEAN CONFERENCE MILANO 7th -8th JUNE 2013 CSG Latest Technology in Refrigeration and Air Conditioning Under the Auspices of the PRESIDENCY OF THE COUNCIL OF MINISTERS

XV EUROPEAN CONFERENCE MILANO 7th -8th JUNE 2013 CSG Latest Technology in Refrigeration and Air Conditioning Under the Auspices of the PRESIDENCY OF THE COUNCIL OF MINISTERS CONCLUSION However, in any case, we need to reduce in all these sectors the energy consumption as well as the use of high-GWP HFCs: we need a gradual phase-down. We still need research and development and permanent updated information: the constraints and thus the innovations will increase fast especially in Europe.
