Solar vehicle-mounted refrigerated storage system

Abstract

The invention provides a solar vehicle-mounted refrigerated storage system. The solar vehicle-mounted refrigerated storage system comprises a power management controller, a storage battery and a refrigeration power device. The power management controller comprises a solar power management module, an automobile power generation power management module, a direct-current boost module and a master control module, wherein the solar power management module is used for managing charging and discharging operation conducted by a solar battery pack on the storage battery, the automobile power generation power management module is used for managing charging and discharging operation conducted by an automobile power source on the storage battery, and the master control module is used for setting working modes and controlling the solar power management module and the automobile power generation power management module to work in the set working mode. According to the invention, solar energy resources are integrated, a solar battery power source and the automobile power source are comprehensively managed through the power management controller and reasonably distributed to the refrigerated storage system, and therefore the situation that the system works in the most energy-saving and most convenient mode is guaranteed; meanwhile, the direct-current power source boost module is added, and therefore the solar vehicle-mounted refrigerated storage system can be applied to vehicle-mounted refrigerated storages with various standards.

Description

technical field [0001] The invention relates to air-conditioning control technology, in particular to a solar vehicle cold storage system. Background technique [0002] Vehicle-mounted cold storage systems have been widely used in many fields in recent years, especially in the transportation of food, medicine and other industries. The traditional on-board cold storage system relies on the fuel consumption of the car to provide electricity and power for the cold storage system. The basic principle is as follows: figure 1 Shown: [0003] When the automobile engine is running, the generator and compressor are driven by the power transmission device (belt, gear, etc.). The refrigerant in the internal pipeline is fully compressed, and then released into the pipeline of the cold storage system for use by the cold storage system. [0004] This method consumes a large amount of fuel to provide power for the cold storage system. On the one hand, a large amount of environmentally h...

Problems solved by technology

Moreover, when the engine stops running (such as temporary parking), the compressor will also stop, so that the cold storage system cannot work. If you want to ensure that the goods in the cold storage are not affected, you must ensure that the engine does not turn off even in the parking state, or That is to say, the goods in the cold storage must be moved to a safe low-temperature environment, which brings great inconvenience to long-distance transportation, and also adds a lot of extra costs
