Refrigerated transport is 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.



Intermodal transport

Vehicle motors

Road congestion: transport sharing, night delivery…

Training of truck drivers

Dimensions of the bodies

Insulation: improving the thermal conductivity of materials (composite structures… )

Thermal losses: opening and closing of doors, joints…

Multi-temperature equipment: it already represents about

1/3rd of new equipment in France for instance

Refrigerant IssuesRefrigerant Issues

The vast majority 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.



Solutions (apart from better control):

Solutions (apart from better 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…)

Each application is different: Refrigeration road transport Mobile Air Conditioning, ...

and thus solutions must be adapted.



CONCLUSIONCONCLUSION

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.
