TRANSPORT REFRIGERATION SYSTEM AND METHOD OF OPERATION

A transport refrigeration unit system () for cooling a trailer compartment () is provided. The transport refrigeration unit system () includes an engine for controlling a cooling rate capacity, the engine operable at a nominal high speed and a nominal low speed. Also included is a controller () in operative communication with the engine to control an engine speed of the engine. Further included is a user interface () in operative communication with the controller (), the user interface () providing a high capacity cooling mode to a user, wherein initiation of the high capacity cooling mode includes the engine operating at a speed greater than the nominal high speed to result in a high capacity cooling rate.
