Explanation of the Working Principle of the backup power system for refrigerated Trucks: Introduction to the 220V/380V external power supply refrigeration systemThe backup power system of the refrigerated truck is used to start when the vehicle engine is not working or malfunctions The second refrigeration power source used, through the backup power system connected to an external power supply, the compressor can also maintain the temperature inside the vehicle compartment and keep the goods fresh normally. It can be used as a temporary refrigeration solution to deal with some unexpected situations, and the refrigerated truck can also be used as a temporary cold storage. During transportation, if a rest is needed or the goods are not unloaded in time after arrival, the backup power supply comes into play. It enables the refrigerated truck to continue supplying the power required for the operation of the refrigerated truck unit through the backup power compressor when the engine is stopped, allowing the goods to maintain a good condition in a constant temperature environment. For some goods with high temperature requirements, All of them can play a very good role.
The backup power system of a refrigerated truck consists of an electric motor, an independent compressor, an external power cord, refrigerant pipelines, etc., which are connected to the original vehicle.The compressors of the refrigeration unit are independent of each other and share the condensing system. The separate compressor for cooling ensures that the vehicle does not need to be started, guaranteeing the temperature of the goods inside the compartment when the vehicle is temporarily parked, breaks down or is under maintenance.
The working principle of the backup power supply for refrigerated trucks: It uses an external power supply of 220V/380V to power the motor and the compressor, driving an independent one The compressor works, providing circulating refrigerant to make the refrigeration unit operate, without the need for the chassis engine to start working. The installation location of the backup power system: It is generally installed beside the frame of the refrigerated truck in a bottom-hanging manner. It can also be installed inside the refrigerated truck’s cargo box (with a compartment and a small outward door).
