Abstract: A cooling system for a variable frequency drive (VFD) of a transport refrigeration unit (TRU) is disclosed. The system comprises a conduit disposed within the vehicle and extending between a opening provided at a first predefined position on the outer body of the vehicle and the VFD being positioned at a second predefined position within the vehicle. The opening facilitates the inflow of ambient air within the conduit that carries the ambient air towards the VFD to enable cooling of the VFD. The system includes a grill cover adapted to be removably attached to the opening and/or the first end of the conduit, which allows entry of the ambient air within the conduit and restricts entry of outside objects and/or living organisms within the conduit.

Abstract: A multi-compartment transport refrigeration system includes a cooling circuit and a hot gas flow path. The hot gas flow path includes an inlet located on the cooling circuit between the compressor and the heat rejection heat exchanger valve; a first outlet located between the first evaporator expansion device and the first evaporator inlet; a second outlet located between the second evaporator expansion device and the second evaporator inlet; a proportional valve downstream of the hot gas flow path inlet; a first evaporator valve located between the proportional valve and the first outlet; and a second evaporator valve located between the proportional valve and the second outlet.

Abstract: A transportation refrigeration assembly includes a modular heat exchanger unit that includes at least one absorption heat exchanger and at least one expansion device. A frame supports the modular heat exchanger unit. A first cooling air outlet is in fluid communication with the modular heat exchanger unit. A second cooling air outlet is in fluid communication with the modular heat exchanger unit.

Abstract: A mounting system for mounting an energy storage device to a trailer includes at least one track defining a path of movement. The at least one track is fixedly mounted to the trailer. At least one guide member is operably coupled to the energy storage device and is movably associated with the at least one track to move the energy storage device along the path of movement between a first position and a second position.

Abstract: A cable management system for a transport refrigeration system includes a trailer comprising an energy storage device and at least one movable axle. The cable management system includes a plurality of track sections extending between the energy storage device and the movable axle and a plurality of fasteners coupling the plurality of track sections. At least one track section of the plurality of track sections is movable such that the plurality of track sections are transformable between a first configuration having a first axial length and a second configuration having a second axial length. The second axial length is shorter than the first axial length.
