Definitions

  • the invention relates generally to the field of transport refrigeration systems. More specifically, the invention relates to transport refrigeration systems employing a series hybrid power supply outputting direct current (DC) to power either a DC or alternating current (ac) compressor motor.
  • DC direct current
  • ac alternating current
  • Transport refrigeration systems such as those used on truck trailers, typically employ a mechanically coupled shaft driven compressor or an electric motor driven compressor.
  • an engine such as a diesel is either directly or indirectly coupled to the refrigeration compressor.
  • the engine may also drive the refrigeration condenser fans, evaporator fans, and other components through additional mechanical drives using pulleys, V-belts and the like.
  • the engine is coupled to an alternator which provides single or polyphase ac power for all refrigeration loads.
  • Refrigeration loads typically include a compressor motor, condenser fan motors, evaporator fan motors, electric defrosting heaters, and other electric loads.
  • What is desired is a system that provides DC to power DC and ac loads .
  • a DC distribution for DC motors provides less expensive motor speed control than ac motors, a lower cost load distribution bus since the number of conductors is reduced as compared with polyphase ac systems as well as the number of contactor poles, and the inherent simplicity in understanding DC systems .
  • a series hybrid power supply system using a DC distribution bus is taught for a trailer box refrigeration system.
  • the trailer box refrigeration system may use either a DC or an ac motor to power its associated compressor.
  • the series hybrid alternator produces power which is full wave rectified for DC refrigeration system loads.
  • One aspect of the invention provides a series hybrid mobile refrigeration power supply system for an electric transport refrigeration system cooling a trailer box.
  • Systems according to this aspect of the invention comprise an engine coupled to an alternator for providing an alternating current output, a rectifier bridge coupled to the output of the alternator for converting the alternating current to direct current, a distribution bus coupled to the rectifier bridge for distributing direct current to a plurality of mobile refrigeration system loads, and a direct current compressor motor electrically coupled to the distribution bus using a contactor as a switching device to energize the compressor motor when required by cooling demand.
  • Another aspect of the invention provides a system for providing electric power for an electric transport refrigeration system used to cool a trailer box.
  • Systems according to this aspect of the invention comprise an engine coupled to an alternator for providing an alternating current output, a rectifier bridge coupled to the output of the alternator for converting the alternating current to direct current, a distribution bus coupled to the rectifier bridge for distributing direct current to a plurality of loads, a compressor motor contactor coupled to the direct current bus, an inverter coupled to the compressor motor contactor for inverting the direct current to an alternating current supplied to the compressor motor when required by cooling demand.
  • FIG. 1 is an exemplary schematic diagram for a series hybrid AC alternator outputting dc to power a dc compressor motor for a trailer box refrigeration system.
  • FIG. 2 is an exemplary schematic diagram for a series hybrid AC alternator outputting dc to power an AC compressor motor for a trailer box refrigeration system.
  • FIG. 1 Shown in FIG. 1 is a first embodiment 101 of a series hybrid dc power distribution system for a mobile refrigeration unit.
  • a gasoline or diesel engine 103 turns a synchronous alternator 105 to generate power for an electric motor 107 that operates a compressor 109 for the mobile refrigeration system.
  • the engine 103 never directly powers the compressor 109.
  • the alternator 105 generates a voltage at a frequency 111 that vary linearly with the angular velocity of the engine 103.
  • the engine 103 speed 113 may be unregulated or regulated using an engine governor (not shown) .
  • the system is designed to operate at a plurality of engine speeds 113, the selection of which is determined by a controller to meet the required conditions of the refrigerated space.
  • the alternator 105 may output single phase or polyphase ac and is used to provide power to the compressor 109 drive motor 107, and may power condenser fan motors, electrically powered evaporator fan motors, serpentine heater elements, evaporator coil heaters, and a host of electrical and electronic control devices such as a suction modulation valve solenoid, a display keyboard module, and the like (not shown) .
  • the structure of the integrally mounted engine driven alternator 105 unit is small to allow it to be easily coupled directly to the drive shaft of an engine 103.
  • a single rotatable drive shaft which is common to both the alternator 105 and engine 103 allows the alternator 105 and engine 103 to be configured to operate as a single unitary mounted unit .
  • the engine 103 may be coaxially coupled to the alternator 105, or may be coupled using an intermediate power transmission device.
  • Various types of mechanical drive mechanisms including gear trains and other known mechanical drive devices may be used.
  • a bridge rectifier for single phase alternator 103 outputs and/or a polyphase diode bridge 115 for polyphase alternator 103 outputs.
  • a bridge rectifier (diode bridge) is an arrangement of diodes connected in a bridge circuit that provides the same polarity of output DC voltage for any polarity of input ac voltage.
  • the bridge recitifier provides full wave rectification from a single phase or polyphase ac input.
  • the rectified DC is output from the rectifier 115 onto a distribution bus 117 for distributing power to all DC fed loads. All major DC loads couple to the bus via single or double pole contactors (relays) 119 controlled by the refrigeration system controller (not shown) .
  • the contactors 119 act as a switch coupling DC 121 distributed by the bus 117 to DC loads such as the compressor 109 motor 107 depending upon cooling demand.
  • the refrigeration system uses an ac motor 203 for the compressor 109.
  • the rectified DC output from the rectifiers 115 is distributed via a bus 117.
  • an inverter 205 inverts the DC to ac 207 which is either directly coupled to the ac motor 203 or through a single or multiple pole contactor
  • the ac motor may be an induction machine or synchronous motor.
  • Typical electric trailer box refrigeration system compressor motors require 3 ⁇ 460 Vac. After inverting, the voltage may be stepped down or up using transformers for electrical loads operating at different potentials (not shown) . DC-DC converters may be used to step down or up the alternator 105 output voltage. Auxiliary loads powered by the refrigeration system may be either selected for use with the generated output voltage, for example 3 ⁇ 460 Vac, or may be used with a voltage conversion device.
