A new modular insulation panel technology for insulating reefer vans is proposed that can solve some of the problems of traditional methods. New insulating materials with lower thermal conductivity and aging rate are considered to be sandwiched in composite panels to provide better thermal performance in addition to stronger structure. The developed technology can be applied on a variety of commercial vans to improve the quality of insulation while reducing the cost and installation time of the process dramatically. The present method suggests prefabricating of modular insulation panels with accurate size in controlled conditions instead of spraying insulation foam inside the vehicles. In addition, the installation method of modular panels enables the operators to replace the damaged parts of insulation easily with less cost instead of changing the whole insulation in the old method. The MATLAB optimization toolbox is utilized to optimize the thickness of insulation panels based on energy cost and operational conditions. To validate the proposed model, a full-scale prototype is built and installed on a Ford transit connect and tested under road conditions for performance approval.
