ROAD 2

Avranches, France–For the second time in only the last few months, Chereau has received another award for its hydrogen refrigerated trailer (Road Project), this time the project has won the 2019 Green Truck Transport Solutions award.

The ROAD project that has a double objective: reduce the environmental impact and improve the operating conditions in terms of ergonomics and safety.

The Project and the challenge 

Refrigerated transport is an essential link in the cold chain, with strong technical and regulatory requirements. The objective of the Refrigerated Optimized Advanced Design (ROAD) project is to develop a new generation of cold chain refrigeration semi-trailers with higher performance technologies, reducing its environmental impact (noise and gas emissions), while improving operating conditions (safety and ergonomics). The three-year project began in September 2016 and is expected to be commissioned by the end of 2019.
The ROAD project partners collaborated on seven complementary technological bricks:

  • Lightening : chassis weight gain through new design and multi-material technologies
  • Aerodynamics : improved semitrailer design for better air penetration and reduced fuel consumption
  • Thermal insulation : new generation of materials with very high thermal performance for the bodywork
  • Energy : clean energy production thanks to an onboard hydrogen fuel cell
  • Production of clean cold : electric refrigeration unit operating with CO2 refrigerant
  • Mechanical and electrical architecture : integration of new components and optimization of the management of electrical and mechanical equipment (reduction of energy consumption, better ergonomics and new security functions)
  • Tests : the concept vehicle will be tested under real conditions of use

The partnership  

CHEREAU was accompanied by AMVALOR, a subsidiary of the National School of Arts and Crafts which carries with it the Carnot Institute ARTS. For example, the Angevin Laboratory of Mechanics, Processes and Innovations (LAMPA) of Arts et Métiers collaborated on three technological bricks: lightening, aerodynamics and thermal insulation.
The on-board instrumentation of a complete vehicle and the tests carried out made it possible to understand the various demands (emergency braking, turns, docking, etc.). The lightening solutions were thus validated, thanks to the use of the numerical model and the test data, without altering the robustness of the chassis. The simulation of the thermal activities (decrease of the overall conductivity coefficient) and aerodynamics (reduction of the overall drag) respectively made it possible to maintain a constant temperature within the refrigerating box and to reduce its energy consumption.
