摘要： 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.
