基于光伏混合制冷系统的冷藏运输车燃油经济性分析

Fuel Economy Analysis of Refrigerated Transporter Based on Photovoltaic Hybrid Refrigeration System

针对冷藏运输车停车后保持发动机以及压缩机工作制冷的问题,提出一种基于双压缩机的冷藏运输车光伏混合制冷系统,建立冷藏运输车光伏混合制冷系统数学模型,并在MATLAB/Simulink中建立其仿真模型,分析在NEDC工况下冷藏运输车的燃油消耗,根据《重型混合动力电动汽车能量消耗量试验方法》换算总燃油消耗量。研究表明:相比于安装传统制冷系统,基于光伏混合制冷系统的冷藏运输车百公里油耗减少大约7.06%。

Aiming at the problem of engine and compressor working and cooling after the refrigerated transporter was parked,aphotovoltaic hybrid refrigeration system for refrigerated transporter based on dual compressors was proposed.The mathematic model of refrigerated transporter photovoltaic hybrid refrigeration system was established and its simulation was established in MATLAB/Simulink Model to analyze the fuel consumption of a refrigerated truck under NEDC conditions.The total fuel consumption was calculated according to the Energy Consumption Test Method for Heavy Hybrid Electric Vehicles.The results show that the fuel consumption per 100 km of a refrigerated transport vehicle based on the PV hybrid refrigeration system is reduced by about 7.06%,compared with the conventional refrigeration system.
