Abstract: Technologies are provided for preventing a working fluid leak from pooling and thus diluting any leaked working fluid from air within a condenser and/or evaporator compartment of the CCU. This can include a computer-readable medium that stores executable instructions that, upon execution, prevent a working fluid leak from pooling within a climate-control unit (CCU) of a transport climate control system. This also includes detecting fulfillment of activation threshold conditions in connection with the CCU. Also, this includes activating a fan in at least one of a condenser unit and an evaporator unit included in the CCU to dilute leaked working fluid from air within the CCU. Further, this includes detecting fulfillment of de-activation threshold conditions and de-activation of an activated fan.

Abstract: A closed loop feedback control and diagnostics system for a transport climate control system is provided. The closed loop feedback control and diagnostics system includes a plurality of source current sensors configured to monitor current received from a high voltage three-phase AC power source. The closed loop feedback control and diagnostics system also includes a plurality of compressor current sensors configured to monitor current drawn by an electrically powered compressor of the transport climate control system. The closed loop feedback control and diagnostics system also includes a controller configured to receive source current signals from each of the plurality of source current sensors, configured to receive compressor current signals from each of the plurality of compressor current sensors, and configured to control operation of the transport climate control system based on the received source current signals and the received compressor current signals.

Abstract: 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.

Abstract: A method for preserving autonomous operation of a transport climate control system is provided. The method includes the controller determining whether a regulatory compliance at a current location is restricting and/or preventing the use of a prime mover for powering the transport climate control system while a transport unit is in transit. When the controller determines that use of the prime mover is not being restricted or prevented because of a regulatory compliance, the method includes operating the transport climate control system and the transport power system in an energy harvesting operation mode for storing excess power generated by the prime mover into the auxiliary energy storage. When the controller determines that use of the prime mover is being restricted or prevented because of a regulatory compliance, the method includes the controller instructing the auxiliary energy storage to provide power to the transport climate control system.
