Patent number: 11692495Abstract: A generator set for a transport climate control unit is provided that is operable at a first frequency and a second frequency. The generator set includes a generator, a prime mover configured to operate at a first non-zero speed and a second non-zero speed that is less than the first non-zero speed, and a genset controller configured to control operation of the generator set. When operating at the first non-zero speed, the genset controller is configured to monitor a prime mover load parameter to determine whether the prime mover is approaching or has exceeded an overload or stall situation. The genset controller is configured to reduce the speed of the prime mover from the first non-zero speed to the second non-zero speed to prevent the overload or stall situation.Type: GrantFiled: April 28, 2022Date of Patent: July 4, 2023Assignee: THERMO KING LLCInventors: John G Simpson, Randy S. Burnham, Kyle J. Gleason

Patent number: 7743616Abstract: A generator set for a transport refrigeration unit that is operable at a first frequency and a second frequency. The generator set includes a generator and a prime mover coupled to the generator. The prime mover selectively drives the generator in least at a first non-zero speed and a second non-zero speed. A sensor is in electrical communication with the generator to sense a load of the generator and to deliver a signal indicative of the generator load. A controller is in electrical communication with the generator, the prime mover, and the sensor, and receives the signal indicative of the generator load. The controller selectively operates the generator at one of the first speed and the second speed in response to the signal indicative of the generator load.Type: GrantFiled: October 12, 2006Date of Patent: June 29, 2010Assignee: Thermo King CorporationInventors: David J. Renken, Bernard Wayne Benson, Randy S. Burnham, Erich Lucht

Patent number: 6595847Abstract: A container for transporting a load in conditioned space air, where the container includes a number of walls defining a closed conditioned space with an ambient air intake opening and a conditioned space air exhaust opening provided on one of the container walls; a temperature control system for controlling the temperature of the conditioned space air; an ambient air exchange so system having a door movable relative to the exhaust and intake openings to thereby change the rate that conditioned space air is exchanged with ambient air, and a motor for repositioning the ambient air exchange door. The container also including a container controller in signal transmitting relation with the air exchange door repositioning motor. The controller sends signals to the repositioning motor to move the ambient air exchange door to a position which produces the required ambient air exchange rate to preserve the load.Type: GrantFiled: November 6, 2001Date of Patent: July 22, 2003Assignee: Thermo King CorporationInventors: Mark Freese, Neil D. Tamppari, Randy S. Burnham
