Summary

The low thermal conductivity of vacuum insulation materials can only partially be realised as a consequence of boundary conditions and heat bridges caused by the insulated construction, especially with small insulation elements. The large specific mass of mineral filling materials is counteracting the trend towards lighter vehicles. Open plastic foams offer conformity with the wishes of the transport industry or of regulatory authorities, at somewhat lower thermal conductivity but better insulation efficiency. Gas release from the material and/or from adhesive resins, and leakage can be counteracted by pumping down again. The repartition of heat loads from external and internal sources and of space between air channels and insulation requires a user-friendly model for the conditioning of cargo in refrigerated spaces.
