The invention discloses a control method and device of a refrigerating unit and a refrigerating machine system, and belongs to the technical field of cold chain transportation. The control method of the refrigerating unit comprises the steps that monitoring information of the refrigerating unit is received in real time and transmitted to a control panel and a remote control module, wherein the monitoring information comprises temperature information and pressure information; the monitoring information is displayed by the control panel; the remote control module transmits the monitoring information to a remote server; and whether control signals are provided for a temperature adjusting device and a pressure adjusting device of the refrigerating unit through the control panel or not is determined, if yes, the control signals are provided for the temperature adjusting device and the pressure adjusting device through the control panel, and if not, the remote server provides the control signals for the temperature adjusting device and the pressure adjusting device according to the monitoring information. By means of the control method and device of the refrigerating unit and the refrigerating machine system, the refrigerating unit can be remotely controlled, so that the abnormity of the refrigerating unit can be found and solved in time, and goods in the refrigerating unit are prevented from being damaged.
