摘要： A transport refrigeration system includes a compressor having discharge and suction ports and at least one electric compressor drive motor disposed within the compressor. The system includes a condenser heat exchanger unit and an evaporator heat exchanger unit operatively coupled, respectively, to the compressor discharge port and the compressor suction port. At least one fan assembly having an electric fan motor is configured to provide air flow over at least one of the heat exchanger units. The system includes an integrally mounted unitary engine driven synchronous generator assembly, which is configured to selectively produce at least one A.C. voltage at one or more frequencies. The compressor drive motor and the at least one fan motor are configured to be directly coupled to the synchronous generator and to operate at a voltage and frequency produced thereby. The compressor is provided with means for unloading at least a portion of the compressor's compressing capability. Controls for the system are provided for selectively energizing the means for unloading the compressor during certain operating conditions of the refrigeration system, such as during start up of the compressor.

摘要： An integrated transport refrigeration unit comprises an engine providing power to drive a shaft. The shaft drives a refrigerant compressor and a generator, both of which being encased within a housing, and the generator is immersed in refrigerant. In an exemplary embodiment, an integrated transport refrigeration unit also includes an auxiliary generator driven by the shaft and disposed externally from said housing. In this embodiment, the auxiliary produces current for charging a battery and for operating a fan.

摘要： The present invention provides for a transport refrigeration unit of the type configured to be mounted on the front wall of a transport trailer. The transport trailer is adapted to be connected to and towed by a motorized tractor. The connected trailer and tractor define between them a predetermined envelope bounded by the tractor swing radius and the trailer front wall. The refrigeration unit includes a structural support framework configured to be attached to the front wall of the trailer. An outer cover is configured to be supported by the framework and to be within the predetermined envelope. All of the following components of the refrigeration unit are supported by the framework and contained within the outer cover: a compressor, a condenser heat exchanger, an evaporator heat exchanger, at least one fan assembly having at least one electric fan motor configured to provide air flow over one of the heat exchangers, and an integrally mounted unitary engine driven generator assembly configured to selectively produce at least one A.C. voltage at one or more frequencies. The generator assembly is capable of producing sufficient power to operate the compressor drive motor and the at least one fan motor. In a preferred embodiment, the generator assembly is a synchronous generator and the compressor drive motor and the at least one fan motor are configured to be directly coupled to the generator and to operate at a voltage and frequency produced by the synchronous generator.

摘要： A transport refrigeration system is connected to a hydraulic system including a pump, control valves, a reservoir and a hydraulic piston. When the refrigeration system is running, the hydraulic system is in a bypassing or idling mode and the diesel and compressor are run responsive to cargo refrigeration requirements. When the hydraulic system is activated, the diesel is caused to operate at a preselected speed for maximum hydraulic flow and the refrigeration electrical system unloads the compressor to divert more engine power to the hydraulic pump.
