Description
Technical field
The present invention is a kind of refrigerated air-conditioning system, the air-conditioning that specifically a kind of engine low-grade energy is recycled
System.
Background technology
With the development of Chinese Automobile Industry ', the energy consumption of conventional fuel oil automobile is growing day by day, automotive energy-saving emission-reducing and how
It is always focus of concern to improve the automobile engine thermal efficiency.Research shows that vehicle fuel energy only has 30% to be used for vapour
Driving, braking, the friction of car, 30% is used to cool down, and remaining about 40% is discharged into air in the form of high temperature automotive tail gas.
Wuhan University of Technology is measured 1.6L discharge capacity fuel-engined vehicle Tail Pipe Temperatures using accurate infrared radiation thermometer, test result
Show engine speed in 3000r/min, engine export Tail Pipe Temperature is up to 450 DEG C or so, blast pipe terminal temperature
Also up to 200 DEG C or so.The discharge of high temperature automotive tail gas is a kind of waste of the energy, not only reduces vehicle fuel and uses effect
Rate, while also polluting environment.The automobile oil consumption in 1 year of one 1.6L discharge capacity is between 1 500~2000L, with current global vapour
1,000,000,000 calculating of car recoverable amount, the annual total oil consumption of Global Auto is about 1.5 × 1012~2 × 1012L.With current 93# gasoline 7.5
Member/L calculation of price, Global Auto will consume the gasoline of about 11.25~15 trillion yuans every year.If can be by the fuel oil of current automobile
Utilization rate improves 10%, and the gasoline of 1.1~1.5 trillion yuans will be saved every year.Improving vehicle fuel utilization rate as can be seen here has
Huge economic benefit.The recycling of automobile high-temperature tail gas is a kind of effective means for improving fuel oil utilization rate.Due to the temperature difference
The cleaning of generation technology green, flexible and changeable, safe and reliable, the U.S., Germany carry out vehicle exhaust thermo-electric generation in succession in recent years
Mesh.The heat energy of high temperature automotive tail gas can be converted into electric energy using thermoelectric generation for car use, not only increase fuel oil
Utilization rate, the saving energy, while also reducing pollution of the vehicle exhaust to environment.USDOE and General Motors cooperative research and development
The electric energy that Chevrolet Surburban automobiles equipped with temperature difference electricity generation device are produced is used for hybrid vehicle, saves fuel oil
10%.In October, 2008, germany volkswagen releases the family car with thermoelectric generator, and 600W electric energy can be provided for automobile, meets
Its 30% need for electricity, reduces fuel oil more than 5%.By the end of the year 2013, China's car ownership reaches 1.37 hundred million, accounts for the whole world
More than the 10% of the total recoverable amount of automobile.Vehicle exhaust thermoelectric generation has huge application market in China
The air conditioning device rate of existing in the market widely used middle-size and small-size lorry and middle bus is only 15% or so, and
What quite a few or automobile were just added up after dispatching from the factory.Truck air conditioning market is the air-conditioning market for being only second to car, and
The enterprise and relevant unit of the riding air-conditioning of studies in China truck are seldom.In general, passive working condition can reduce a people
Work and activity efficiency, and the major reason that traffic accident occurs is exactly the passive feelings brought of fatigue of driver
Thread.Country internet is financial at present, and electric business industry etc. is developed rapidly, drives developing rapidly for logistics major, increasing to carry
Lorry is to and between two places, so, it is particularly important that the refrigeration system to lorry, which optimizes upgrading,.
During summer, the vehicle for being parked in open-air atmosphere is irradiated by strong light, and vehicle interior temperature is up to more than 60 DEG C, driver
Substantially done not feel like oneself when having just enter into car, and on-board air conditioner refrigeration needs 15~20min, the problem of winter also has similar, winter
In-car air is heated, it is necessary to first start engine, and long and cost is high the time required to heating.So, a kind of convenient, cost is low
Mounted air conditioner system is that all vehicles are later necessary from now on.
