Efficient control algorithm for start-stop operation of a refrigeration unit powered by engine
A refrigeration unit and a method for controlling same during start-stop operation is provided. The refrigeration unit may include an engine operable between at least a low engine speed and a high engine speed, a compressor operatively coupled to the engine, and a controller operatively coupled to each of the engine and the compressor. The controller may be configured to operate the engine at a reduced low speed during a delay period, extend the delay period based on the reduced low speed, increase a displacement capacity of the compressor based on the extended delay period, and operate the engine at a reduced high speed.
