초록 ▼

The performance of a transport refrigeration system (12) having a transport refrigeration unit powered by a diesel engine is optimized by matching a capacity output of the transport refrigeration unit to an available shaft power of the diesel engine. The power consumption of the transport refrigeration may be controlled by selectively limiting refrigerant mass flow through the refrigerant circuit of the transport refrigeration unit in response to an operating engine load and an operating speed of the diesel engine.

대표청구항 ▼

1. A method for optimizing the performance of a transport refrigeration system having a transport refrigeration unit powered by a diesel engine, comprising matching a capacity output of the transport refrigeration unit to an available shaft power of the diesel engine; the method further comprising: monitoring an operating engine load of the diesel engine;monitoring an operating engine speed of the diesel engine:operating the transport refrigeration system at the capacity output necessary to meet a current refrigeration demand load so as long as both the operating engine load of the diesel engine is not at 100% and the operating speed of the diesel engine is at least 98% of a target engine operating speed; andreducing the cooling capacity output of the refrigeration unit when the operating engine load of the diesel engine is greater than 90% and an operating speed of the diesel engine is less than 98% of a target engine operating speed. 2. The method of claim 1 wherein the transport refrigeration unit includes a compressor having a compression mechanism drive shaft driven by a shaft of the diesel engine. 3. The method of claim 2 wherein the engine shaft directly drives the compression mechanism drive shaft. 4. The method of claim 2 wherein the engine shaft drives an electric generator for generating electrical power to power a compressor drive motor for driving the compressor. 5. The method of claim 1 wherein the operating engine load of the diesel engine is indicated by a fuel rack position.
