摘要： A method of remotely managing a transport climate control system (TCCS) includes a remote management device receiving performance data from the TCCS. The performance data based on one or more detected operating parameters of the climate control circuit. The method also including the remote management device providing the performance data to one or more user devices. A remote management system includes a remote management device configured to receive performance data for a climate control circuit from a climate controller of a TCCS and to provide the performance data to one or more user devices. A TCCS includes a controller configured to: generate performance data based on the one or more detected operating parameters of a climate control circuit, and transmit the performance data to a remote monitoring device. The climate controller also configured to receive an operating instruction from the remote monitoring device.

摘要： 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.

摘要： 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.

摘要： A system and method for temperature control for a Transport Refrigeration System (TRS) is provided. Particularly, a method for temperature control of an internal space of a refrigerated transport unit is provided. The method includes determining a measured internal space temperature within the internal space of the refrigerated transport unit. The method also includes calculating, via a TRS controller, a temperature difference between the measured internal space temperature and a desired set point temperature. Also, the method includes adjusting, via the TRS controller, a duty cycle percentage of a liquid line solenoid valve and/or a hot gas solenoid valve based on the temperature difference to control an amount of refrigerant directed to the thermal expansion device and the evaporator and/or an amount of hot gas directed to the evaporator.

摘要： A method of feedthrough and overcurrent protection of a sealed compressor used in a transport climate control system (“TCCS”) is provided. The TCCS includes a climate control circuit with a sealed compressor. The sealed compressor includes an outer housing and an electrical motor within the outer housing. The method includes operating the sealed compressor to compress a working fluid by supplying electrical power to the electric motor of the sealed compressor via a sealed electrical feedthrough in the outer housing of the sealed compressor. The method also includes detecting an operating parameter of the sealed electrical feedthrough, and determining whether the sealed electrical feedthrough is in a melting condition based on the detected operating parameter. Also, the method includes adjusting operation of the climate control circuit upon determining that the sealed electrical feedthrough is in the melting condition until the sealed electrical feedthrough is no longer in the melting condition.
