Abstract: A transportation refrigeration unit (24) to provide a flow of supply air to a selected space includes a compressor to compress a flow of refrigerant and an engine (36) powered by a flow of fuel and operably connected to the compressor to drive the compressor. An evaporator circulates the flow of refrigerant therethrough to cool the supply air and includes a substantially unitary evaporator housing (50) having a supply air inlet opening (52) and a supply air outlet opening (56). An evaporator coil (32) is located in the evaporator housing, the flow of refrigerant circulating across the evaporator coil. An evaporator fan (34) is located in the evaporator housing to urge the supply airflow into the evaporator housing via the supply air inlet opening (52), across the evaporator coil (32) and out of the evaporator housing through the supply air outlet opening (56). The evaporator fan (34) can be located upstream or downstream of the evaporator coil (32).

Abstract: A transportation refrigeration system is provided including a tractor cabin having an engine and an engine cooling system. A trailer is operably coupled to the tractor cabin. A transport refrigeration unit is configured to maintain a controller temperature environment of a portion of the trailer. The transport refrigeration unit is mounted to a front surface of the trailer adjacent the truck. A shield (50) is mounted to at least one of the tractor cabin, trailer, and transport refrigeration unit. The shield is configured to block an air flow path between an area (42) of discharge air from the engine cooling system and a condenser air inlet (32) of the transport refrigeration unit.

Abstract: An electrical connection assembly (300) for an evaporator module (302) comprising a heat exchanger and a fan is provided. The assembly includes a frame fixedly connected to an exterior of an evaporator, and a tray (322) having at least one aperture in a wall thereof and supporting a quick-connect electrical system (324), the tray configured within at least a portion of the frame. The tray is movable from a first position to a second position, the first position being a closed position wherein the quick-connect electrical system is secured within the frame, and the second position shown in FIG. 3B being an open position that is removed from the first position and configured to enable access to the quick-connect electrical system within the tray.
