Cold storage transportation car adopting hybrid power drive refrigeration system

Abstract

The invention discloses a cold storage transportation car adopting a hybrid power drive refrigeration system. The cold storage transportation car comprises multi-path charging switches arranged on theouter surface of a cold storage compartment and connected in parallel through a photovoltaic controller and solar photovoltaic plates connected with charging ports of multiple storage batteries connected in parallel. Power transmission ports of the multiple storage batteries are connected with the power supply end of a compressor of a refrigeration system for supplying the cooling capacity to thetransportation compartment through multi-path discharge switches connected in parallel. The multiple storage batteries are connected with an internal combustion engine energy supply system through the multi-path charging switches connected in parallel. According to the cold storage transportation car, the storage batteries are constantly used for providing electric energy for the refrigeration compressor, it can be guaranteed that the compressor stably runs all the time, the service life of the compressor can be better prolonged, and the efficiency of the refrigeration system is improved. Theinternal combustion engine energy supply system only charges the storage batteries, an internal combustion engine can continuously run in the optimal design work condition, the heat efficiency of theinternal combustion engine can be better improved, and the service life of the internal combustion engine can be better prolonged; and the surface of the compartment is covered with the solar photovoltaic plates, radiation heat loads caused by sunlight irradiation can be weakened, and total energy consumption can be reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerated transport, in particular to a refrigerated transport vehicle adopting a hybrid drive refrigeration system. Background technique [0002] With the development of the economy and the improvement of people's living standards, consumers have an increasing demand for foods with high nutritional value such as fresh fruits, vegetables, seafood, and meat products, and they have also put forward stricter requirements for quality. The freshness of fresh food when it reaches consumers depends largely on the temperature control in the logistics process, which will promote the gradual expansion of cold chain logistics. Refrigerated transport vehicles are one of the core links of cold chain logistics, and their demand will further increase. [0003] At present, common refrigerated transport vehicles mainly rely on independent internal combustion engines to directly drive refrigeration compressors to provi...

Problems solved by technology

However, the power of the internal combustion engine used is generally small and the thermal efficiency is low, resulting in a large amount of energy consumption in the cooling process; in addition, the internal combustion engine is often running at an unstable speed, resulting in large fluctuations in the speed of the compressor, which makes the cooling capacity not well matched with the load in the car And reduce the life of the compressor
