    • A power supply system for a transport refrigeration system (20) includes an engine (26) coupled to a compressor (32) of a refrigeration unit for direct drive powering the compressor (32) and a generator (24) arranged to also be direct driven by the engine (26) for generating electric power. The generator (24) and the compressor (32) are mounted to a common drive shaft (25) driven by the engine (26), and the generator (24) may be integrated with the compressor (32). The power supply system may further include an alternator (50) arranged to be belt driven by the engine (26) for generating DC electric power. A battery pack (28) may be provided for storing and supplying additional DC power. During peak load demand on the refrigeration unit (20), the engine (26) may be operated with the generator (24) switched off to directly drive the compressor (32) and direct current may be drawn from the battery pack (28) to drive the condenser/gas cooler and evaporator fans (40, 44).
    • 用于运输制冷系统(20)的供电系统包括联接到用于直接驱动对压缩机(32)供电的制冷单元的压缩机(32)的发动机(26)和布置成也被直接驱动的发电机 通过用于产生电力的发动机(26)。 发电机(24)和压缩机(32)安装到由发动机(26)驱动的公共驱动轴(25)上,发电机(24)可与压缩机(32)集成。 电源系统还可以包括布置成由发动机(26)带动的用于产生直流电力的交流发电机(50)。 可以提供用于存储和提供附加DC电力的电池组(28)。 在制冷单元(20)的峰值负载要求期间,发动机(26)可以在发电机(24)关闭以直接驱动压缩机(32)的情况下操作,并且直流电可以从电池组(28)抽出到 驱动冷凝器/气体冷却器和蒸发器风扇(40,44)。
