| Zusammenfassung: | The utility model provides a refrigerator car temperature control device and system. The refrigerator car temperature control device comprises a return air temperature sensor arranged at an inlet of a refrigeration return air pipeline, an air supply temperature sensor arranged at the tail end of a refrigeration air supply pipeline, a CPU and a control circuit. The CPU and control circuit controls the air supply temperature sensor or the air return temperature sensor to be started according to an input selection instruction. According to the refrigerator car temperature control device, the two temperature sensors are arranged and installed in the air supply pipeline and the air return pipeline respectively, different temperature sensors are selected as reference temperatures for controlling an air conditioning system according to different requirements of refrigeration and freezing, and articles stored in the air supply pipeline in the refrigeration process are prevented from being frostbitten.
