Abstract

An engineless transport refrigeration unit includes a compressor constructed and arranged to compress a refrigerant, and a compressor motor configured to drive the compressor and operate at a voltage range of two hundred (200) to six hundred (600) volts. A battery of the engineless transport refrigeration unit provides the power to the compressor motor.

First claim

What is claimed is:

1. A tractor trailer system comprising:
a self-propelled tractor including a combustion engine and a generator driven by the combustion engine;
a transport container adapted to be connected and towed by the self-propelled tractor;
and
an engineless transport refrigeration unit mounted on the transport container, the engineless transport refrigeration unit comprising a compressor constructed and arranged to compress a natural refrigerant having a GWP of about one, a direct current compressor motor configured to drive the compressor, a condenser heat exchanger operatively coupled to the compressor, a condenser fan configured to provide air flow over the condenser heat exchanger, a condenser fan motor for driving the condenser fan, an evaporator heat exchanger operatively coupled to the compressor, an evaporator fan configured to provide air flow over the evaporator heat exchanger, an evaporator fan motor for driving the evaporator fan, and an energy storage device configured to provide direct current electric power to the compressor, condenser and evaporator fan motors, and wherein the energy storage device is configured to provide power within a range of two hundred volts to six hundred volts and to be recharged by the generator, and wherein the compressor motor is configured to operate at a direct current voltage range of two hundred to six hundred volts.

2. The tractor trailer system set forth in claim 1 , wherein the energy storage device is a battery.

3. The tractor trailer system set forth in claim 2 , wherein the engineless transport refrigeration unit includes a renewable source of power configured to recharge the battery.
