Technologies described herein are directed to isolating or insulating at least portions of an evaporator coil within a climate control unit (CCU) of a TCCS so as to reduce or even eliminate adverse effects caused by a leaked working fluid. Such adverse effects may include a threat of ignition, asphyxiation of occupants, damage to cargo, and other harmful effects caused by emission of a noxious gas. A leak isolation structure is provided to isolate evaporator tubes of an evaporator coil from at least one of a plurality of turns of the evaporator coil.

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).

A material transportation system for a working machine is provided. The material transportation system comprises a load implement body with a plurality of air flow channels. The air flow channels comprise a set of heat insulated air flow channels, and a set of heat transfer channels, wherein each air flow channel of the set of heat insulated air flow channels comprises a heat insulating structure. When the temperature level of the load implement body is below a predetermined threshold limit, pressurized air is directed to the set of heat transfer channels.

A railcar backup cooling system may be added to an existing railcar (e.g., a boxcar) to provide supplemental or backup cooling to the railcar in the event that an HVAC failure or other circumstance occurs, which causes the interior temperature of the railcar to rise. The system includes a container of liquid or compressed gas mounted on the railcar, a valve controlling the flow of the liquid or gas from the container, and a controller configured to open the valve when the HVAC system fails or is otherwise unable to maintain the railcar at the desired temperature. When the valve is opened, the liquid and/or gas stored in the container may exit, expanding into a cool gas and thereby acting to cool the railcar environment.
