Abstract
A transport refrigeration unit system (26) for cooling a trailer compartment (24) is provided. The transport refrigeration unit system (26) 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 (50) in operative communication with the engine to control an engine speed of the engine. Further included is a user interface (52) in operative communication with the controller (50), the user interface (52) 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.
Claims12
A method of operating a transport refrigeration unit system comprising:
- providing a high capacity cooling mode on a user interface;
- controlling a cooling rate capacity of the transport refrigeration unit system with an engine that is operable at a nominal high speed and a nominal low speed;
- controlling an engine speed of the engine with a controller;
- and
- initiating the high capacity cooling mode through a selection on the user interface, the high capacity cooling mode including operating the engine at a speed greater than the nominal high speed to result in a high capacity cooling rate;
- wherein a transport operating mode of the engine includes operation of the transport refrigeration unit system within a temperature control band while the trailer compartment is moving;
- wherein the high capacity cooling mode is not available during the transport operating mode.
