A parking charging and cooling control system for refrigerated vehicles

Abstract

The invention provides a parking charging and cooling control system for a refrigerated vehicle, and relates to the technical field of manufacturing charging equipment for a refrigerated vehicle. The system includes a transformer, a rectifier circuit, a filter circuit, a charging circuit, and a refrigeration circuit; the utility power passes through a series-connected transformer, rectifier circuit, and filter circuit in turn, and outputs a voltage that matches the battery of a refrigerated vehicle; the transformer converts the utility power into a value suitable for refrigeration The charging voltage of the car battery; the rectifier circuit rectifies the alternating current after stepping down the transformer into direct current; the filter circuit eliminates the ripple in the waveform output by the rectifier circuit; the output port of the filter circuit is connected to the parallel charging circuit and refrigeration circuit; The circuit charges the battery of the refrigerated truck, and determines the charging method according to the state of charge of the battery; the refrigeration circuit provides power for the refrigerator of the refrigerated truck. The parking charging and refrigeration control system of the refrigerated vehicle provided by the invention can reduce the exhaust emission of the vehicle and reduce the cost of electricity consumed by opening the refrigerating equipment when loading and unloading goods.

Description

technical field [0001] The invention relates to the technical field of manufacturing charging equipment for refrigerated vehicles, in particular to a parking charging and cooling control system for refrigerated vehicles. Background technique [0002] At present, with the steady advancement of my country's urbanization process, the number and scale of large and medium-sized cities are increasing year by year. The demand for fresh agricultural by-products and frozen food in these cities is also increasing day by day. At present, different refrigerated trucks or refrigerated trucks are often used in urban logistics to realize the terminal distribution of fresh fruits and vegetables or frozen food. At present, most of the refrigerated trucks in the market are mechanical compression refrigeration, which has the disadvantages of inaccurate temperature control, high energy consumption, complex refrigeration system, and low reliability. Cold storage refrigerated vehicles have beco...
