Patent attributes
Self-contained refrigeration units include evaporator modules, condenser modules, compressor modules, control subassemblies, and all other refrigeration components in compact interconnected modular packages. The modules, which are assembled in rigid or flexible self-contained monoblock refrigeration units, are installable, removable and replaceable as complete self-contained refrigeration units without requiring transport downtime for servicing and repairing of the refrigeration units. Vehicles with refrigeration systems arrive at a distributor and have malfunctioning units removed and complete units replaced and installed and are back on the road within minutes. Dealers' inventories are small and non complex and dealers' workers need not be skilled transport refrigeration mechanics. Dealer trucks have light cranes to remove and replace complete self-contained refrigeration units on site.
