摘要： A method for monitoring fuel quality of a power system used in transport is provided. The method includes a controller of the power system determining that the prime mover is actively running. The method also includes the controller monitoring an output of a water-in-fuel (WIF) sensor configured to measure an amount of water accumulated in a water collection reservoir of a fuel/water separator that separates water from fuel passing there through. Also, the method includes the controller determining an amount of fuel passing through the fuel/water separator. Further, the method includes the controller calculating a fuel quality score of the fuel based on the output of the WIF sensor and the amount of fuel having passed through the fuel/water separator. The method further includes the controller triggering different alerts based on the calculated fuel quality score.

摘要： According to a first aspect there is disclosed an assembly comprising a power device and a cooling plate which overlies the power device for heat transfer therebetween. The power device comprises a plurality of power switching components including at least a first power switching component and a second power switching component; wherein each of the power switching components is configured to dissipate heat to the cooling plate. The cooling plate comprises a plurality of cooling zones overlying and aligned with the respective power switching components for heat transfer, including first and second cooling zones corresponding to the first and second power switching components; and a flow channel for a cooling flow, extending between an inlet and an outlet through each of the cooling zones; wherein a geometric parameter of the flow channel that at least partly determines heat transfer in a respective cooling zone differs between the first and second cooling zones for improved heat transfer in the first cooling zone relative to the second cooling zone. According to a second aspect, there is disclosed a method for cooling the plurality of power switching components in an assembly in accordance with the first aspect.

摘要： There is disclosed an electrical connection unit for a refrigeration system comprising: a container defining an interior for containing electrical circuitry, the container having an external port configured to couple with an external connector; a closure moveable relative to the container between a closed configuration in which access to the interior is prevented, and an open configuration in which access to the interior is permitted. The closure has a locking portion defining a connector opening for receiving the connector, configured so that movement of the closure to the open configuration is prevented by interlocking engagement of the connector and the closure. There is also disclosed an associated method of coupling or decoupling a connector and an electrical connection unit.

摘要： A transport refrigeration system (TRS) includes a first heat transfer circuit including a first compressor, a condenser, a first expansion device, and a cascade heat exchanger. The first compressor, the condenser, the first expansion device, and the cascade heat exchanger are in fluid communication such that a first heat transfer fluid can flow therethrough. The TRS includes a second heat transfer circuit including a second compressor, the cascade heat exchanger, a second expansion device, and an evaporator. The second compressor, the cascade heat exchanger, the second expansion device, and the evaporator are in fluid communication such that a second heat transfer fluid can flow therethrough. The first heat transfer circuit and the second heat transfer circuit are arranged in thermal communication at the cascade heat exchanger such that the first heat transfer fluid and the second heat transfer fluid are in a heat exchange relationship at the cascade heat exchanger.

摘要： There is disclosed a transport refrigeration system comprising an electronically governed engine that drives a refrigeration circuit of the system. The engine control unit is configured to operate the engine in a droop mode of operation, in which the engine speed increases with decreasing engine loads from the refrigeration circuit, so as to maximise the cooling capacity of the system at low engine load conditions.

摘要： Embodiments of systems and methods for a TRS to automatically sense a voltage level and configuration of an input AC power provided by an AC power source and automatically adapt to the input AC power being used are provided. When the voltage level of an input AC power supplied to a TRS changes, the TRS can automatically detect the change of the voltage level, and adjust a winding configuration of a compressor motor of the TRS and a voltage level of the TRS based on the detected voltage level of the input AC power.
