  • Device and method for extending the lifespan of a shaft seal for an open-drive compressor
    Patent number: 10801623
    Abstract: A device and method for extending the lifespan of a shaft seal for an open-drive compressor is provided. The device and method can also reduce and/or prevent deterioration of the shaft seal regardless of the operation condition of the open-drive compressor. The device and method can further reduce and/or prevent leakage of a lubricant and/or refrigerant that can cause deterioration of components within a transport refrigeration unit (TRU).
    Type: Grant
    Filed: February 8, 2018
    Date of Patent: October 13, 2020
    Assignee: Thermo King Corporation
    Inventors: Joseph Robert Kaiser, David John Dykes, Ralph David Price, Ryan Michael Fritts
  • Device and method for enhancing heat exchanger airflow
    Patent number: 10226985
    Abstract: Devices and methods for enhancing heat exchanger airflow in a transport refrigeration system (TRS) of a refrigerated transport unit are provided. In particular, a fairing is provided on a top surface of a TRU to shield the TRU from an adverse effect of wind (e.g., ram air) and build a negative pressure at a heat exchanger fan delivery side of the TRU. The angle, shape and height of the fairing can be optimized to achieve a desired heat exchanger airflow through condenser coil(s), a radiator and/or intercooler of the TRU during operation.
