Disclosed is a system for managing power in a transport refrigeration unit (TRU) installed on a trailer, having: a TRU controller configured to execute a range extender mode of operation to manage operations of the TRU and TRU components, wherein the TRU controller: selects a power management strategy from a plurality of demand-side power management strategies; determines, from the selected power management strategy, operational parameters for a TRU; and executes the generated operational parameters.

A cold energy storage evaporator is used in a vehicle refrigeration cycle device configured to cool a vehicle compartment. The cold energy storage evaporator includes a refrigerant tube through which a refrigerant flows, and a cold energy storage member that is in close contact with the refrigerant tube, the cold energy container accommodating therein a cold energy storage member configured to freeze due to heat absorption by the refrigerant. A melting point of the cold energy storage member is higher than 11 degrees Celsius.

Methods and systems for controlling a transport refrigeration system are provided. In one instance, the method includes identifying an operational mode change request for a heat exchanger unit of the transport refrigeration system. The method also includes preparing the transport refrigeration system for the operational mode change of the heat exchanger unit, wherein preparing the transport refrigeration system for the operational mode change of the heat exchanger unit includes performing a load control action, the load control action preventing a power source of the transport refrigeration system from at least one of operating outside of a predefined revolutions per minute (RPM) bandwidth and exceeding a predefined power limit of the power source. Also, the method includes changing the operational mode of the heat exchanger unit; and removing the load control action.

A refrigerant circulation system which circulates CO.sub.2-containing refrigerant therethrough includes a compressor which compresses the refrigerant, a motor, a motor speed sensor which detects a rotational speed of the motor, and a control device which controls at least the motor. The motor includes a rotor, a stator, a rotation shaft coupled to the rotor, and slide bearings supporting the rotation shaft and being lubricated using the refrigerant compressed by the compressor, and is configured so that the refrigerant passing through the motor expands after flowing out of the slide bearings and is used for cooling one of the rotor and the stator. The motor further includes a flow rate adjustment mechanism which adjusts a flow rate of the refrigerant. The control device controls the flow rate adjustment mechanism to adjust the flow rate of the refrigerant according to the rotational speed detected by the motor speed sensor.

A refrigeration system having a heat pump function for a motor vehicle. The refrigeration system includes: a refrigerant compressor which is connectable or connected to a primary line; a directly or indirectly acting external heat exchanger, which is arranged in the primary line; a first evaporator, which is arranged in the primary line; a first directly or indirectly acting heat exchanger, in particular a chiller, which is arranged fluidically in parallel to the evaporator; and a refrigerant collector arranged on the low-pressure side. A single sensor device is arranged downstream of the evaporator and the further heat exchanger, in particular the chiller, which is configured to detect the pressure and the temperature of the refrigerant on the low-pressure side of the refrigeration system.
