Abstract: A refrigeration installation method and system for transportable containers. The refrigeration system comprising at least one refrigeration panel readily attachable to the interior walls of the refrigerated compartment of a truck, rail car, trailer, or shipping container. Each panel includes a heat transfer member that also acts as a protective liner which forms the exterior surface of each panel. The liner protects a layer of insulation, which has its inner surface bonded to the interior surface of the liner, from contact with the goods transported within the refrigerated compartment. The layer of insulation insulates and protects a refrigeration coil which is also affixed to or is made part of the interior surface of the liner. The outer surface of the layer of insulation is placed in contact with the interior walls of the refrigerated compartment.
