A transport refrigeration unit controls temperature within a transport refrigeration unit using a remote sensor or sensors. The transport refrigeration unit monitors cargo temperature with remote sensor(s) and air temperature to adjust air delivery speed or cooling capacity. Selected operation parameters are determined with consideration of both energy conservation and/or cargo quality. The transport refrigeration unit controls temperature using a first selected mode of operation or a second mode of operation.

Transport refrigeration system, transport refrigeration unit, and methods for same

A refrigeration system includes a compressor having a first stage and a second stage; a heat rejecting heat exchanger including an inter-cooler and a gas cooler, the intercooler coupled to an outlet of the first stage and the gas cooler coupled to an outlet of the second stage; an unload valve coupled to an outlet of the intercooler and a suction port of the first stage; a flash tank coupled to an outlet of the gas cooler; a primary expansion device coupled to an outlet of the flash tank; a heat absorbing heat exchanger coupled to an outlet of the primary expansion device, an outlet of the heat absorbing heat exchanger coupled to the suction port of the first stage; and a controller for executing a startup process including controlling the unload valve to direct refrigerant from the intercooler to the suction port of the first stage.
