Zusammenfassung:	The utility model provides a refrigerating unit of an electric refrigerator car. The refrigerating unit comprises a controller, a first relay, a second relay, a frequency converter in signal connection with the controller, an electric compressor electrically connected with the frequency converter through the first relay, and a heating wire electrically connected with the frequency converter through the second relay. The controller is in control connection with the first relay and the second relay respectively; the controller is used for controlling and adjusting parameters of the frequency converter, controlling communication between the frequency converter and the electric compressor through the first relay, and controlling communication between the frequency converter and the heating wire through the second relay. According to the refrigerating unit of the electric refrigerator car, the compressor and the heating wire are respectively controlled to work through the frequency converter, so that the heating p
