Hybrid power refrigerated truck structure coupled with combined cooling and power supply type waste heat recovery system

Abstract

The invention provides a hybrid power refrigerated truck structure coupled with a combined cooling and power supply type waste heat recovery system and an operation method of the hybrid power refrigerated truck structure, which are applied to the field of cold-chain transportation and comprise a hybrid power driving system, the combined cooling and power supply type waste heat recovery system and a refrigerated truck body, the truck adopts a hybrid power driving method, so that an engine and a motor can run in an efficient interval, engine waste heat parameters are stabilized and improved, a waste heat recovery system is promoted to more fully and effectively recover waste heat energy of cylinder sleeve water and waste gas from the engine, and refrigerating capacity and electric energy required by the refrigerated truck are output; the refrigerating capacity output meets the cold load of a truck air conditioner and goods refrigeration, the truck air conditioner and an independent refrigerator can be completely replaced, the electric energy meets the electricity utilization requirement of truck electrical equipment, a power source in a hybrid power pure electric driving mode is supplemented, the overall efficiency and the primary energy utilization rate of a truck are comprehensively improved, the oil consumption of the whole truck is reduced, and the cost is reduced. And the purposes of energy conservation and emission reduction are achieved.

Description

technical field [0001] The invention belongs to the field of cold chain transportation, and relates to a truck energy-saving system, in particular to a hybrid refrigerated truck configuration coupled with a combined cooling and electricity waste heat recovery system. Background technique [0002] At present, the working efficiency of internal combustion engines for vehicles is generally lower than 50%, resulting in a large amount of energy loss and carbon dioxide emissions. Nearly half of the energy is lost in the form of waste heat. The waste heat recovery technology of internal combustion engines can effectively recover and utilize low-grade heat sources and convert them It has become the core technology to improve the primary energy utilization rate of the system and the efficiency of the internal combustion engine. However, due to the constraints of the transient pulsation characteristics of the heat source of the vehicle internal combustion engine and the demand for com...

Problems solved by technology

On the other hand, the refrigerating process of refrigerated trucks consumes a lot of extra energy. The waste heat recovery system of combined cooling and power supply can be established to meet the cooling demand and avoid the additional energy consumption of refrigeration. If the system is designed, how to establish a high compactness and Integrated cooling and power cogeneration waste heat recovery system is also a big problem
