Abstract
A transport refrigeration unit and a method for controlling the transport refrigeration unit, wherein the transport refrigeration unit has a controller device for operating a compressor of the transport refrigeration unit with a continuously-variable speed, which allows the compressor to run continuously but with a smooth gradient range of speed variations. The controller device allows the transport refrigeration unit to have a start-stop operation stage, continuous run operation stage, and/or a cycle-sentry operation stage.
