The utility model discloses an energy-saving environment-friendly automotive air conditioning system which comprises a high-pressure heat exchanger forming closed circulation, a condenser, an evaporator, a low-pressure absorption device, an intermediate heat exchanger and a circulation pump. A power driving portion of a compressor of an original air conditioning system of an automobile and an engine are separated, so that power of the engine is not consumed, waste heat of the engine is absorbed by the system, and heat energy is converted into physical power of refrigerant circulating refrigeration to provide kinetic energy for air conditioning refrigeration of the automobile; and the waste heat of the engine of the automobile serves as a main power source of the system, so that fuel consumption is reduced, using cost of the vehicle is lowered, harmful substances discharged by fuel are reduced, and the energy-saving environment-friendly automotive air conditioning system accords with energy-saving and environment-friendly policies advocated by the nation.
Description
Technical field
The utility model relates to a kind of refrigerated air-conditioning system, is specifically related to a kind of energy-efficient, environment-friendly automobiles air-conditioning system of utilizing automobile engine waste heat to freeze.
Background technology
The Chinese Auto Industry development is swift and violent, Car Industry particularly, the rapid growth of automobile quantity, caused simultaneously the quickening that expends of the energy, automobile year, the fuel consumption amount was equivalent to more than 40% of national fuel oil total flow, in the energy that gasoline combustion produces, only have 30% left/right rotation to change into so that the mechanical energy that engine can be worked, and remaining 70% all be heat energy, wherein about 50% by exhaust emissions, vehicle exhaust just from engine out the time temperature generally about 500 ℃, when it through piping, when finally being discharged into external environment, usually also between 150 ℃ ~ 200 ℃, if vehicle exhaust all is discharged in the environment, adds near about 200 ℃ high hot temperature and to contain a large amount of oxious components in the tail gas, not only contaminated environment also can be brought the problems such as greenhouse effects, estimates that the tail vapour of an automobile discharge can have influence on the ground area of tens square metres of motor vehicle environments.
Automotive air-conditioning system be realize to air in a car compartment freeze, the device of heating, ventilation and air cleaning, it can provide comfortable by bus environment for rider person, reduce driver's fatigue strength, improve traffic safety, aircondition has become weighs whether one of complete sign of automobile function.
Existing various automotive air-conditioning system mainly drives refrigeration compressor by engine by electromagnetic clutch, and refrigerant is circulated in the system that the parts such as condenser, evaporimeter form, and reaches refrigeration.In the existing automotive air-conditioning system, the liquid refrigerant that refrigerant gas after compressor will absorb heat from evaporimeter is compressed into HTHP again enters the liquid that condenser is cooled to normal temperature high voltage, after throttling expansion, enter evaporation endothermic in the evaporation, reduce the temperature in the railway carriage, what this compression refrigeration cyclic process consumed is the mechanical energy that engine fuel transforms, the energy consumption of orthodox car air-conditioning system roughly can account for 10% ~ 15% of whole automobile energy consumption, if use the consumption of this process instead heat energy, just can utilize a large amount of used heat of automobile engine, so not only saved the prime mover in the existing air-conditioning system, compressor, electromagnetic clutch and oil lubrication system, also can save mass energy, eliminate noise.
The utility model content
The utility model provides a kind of energy-efficient, environment-friendly automobiles air-conditioning system of utilizing waste heat of automotive exhaust gas to freeze.
The technical solution of the utility model: a kind of energy-efficient, environment-friendly automobiles air-conditioning system comprises the hp heat exchanger, condenser, evaporimeter, low-pressure absorption device, intermediate heat exchanger, the circulating pump that consist of closed cycle; Described hp heat exchanger one end connecting engine exhaust outlet, an end connects condenser; Condenser connects evaporimeter; Described low-pressure absorption device is closed container, and an end connects evaporimeter, and an end connects respectively intermediate heat exchanger and circulating pump; Interconnect between described intermediate heat exchanger and the circulating pump, intermediate heat exchanger is connected with hp heat exchanger.
Be provided with reservoir, filter and choke valve between described condenser and the evaporimeter.
Be provided with filter and choke valve between described low-pressure absorption device and the intermediate heat exchanger.
But the exhaust outlet of described hp heat exchanger one end setting combustion gas.
Technique effect of the present utility model: the energy-efficient, environment-friendly automobiles air-conditioning system is separated the original air-conditioning compressor power drive part of automobile and engine, the power of consumption of engine not, engine waste heat is absorbed by native system, the physics power that its heat energy is changed into the refrigerant circulation refrigeration provides kinetic energy to automobile air-conditioning refrigeration, the main power source of native system comes from the engine waste heat of automobile, not only saved fuel consume, reduced the use cost of vehicle, also reduce the harmful substance of discharging because of fuel oil, met the energy-saving and environment friendly policy that country advocates.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of energy-efficient, environment-friendly automobiles air-conditioning system comprises the hp heat exchanger 1, condenser 2, evaporimeter 3, low-pressure absorption device 4, intermediate heat exchanger 5, the circulating pump 6 that consist of closed cycle; Described hp heat exchanger 1 one end connecting engine exhaust outlets, an end connects condenser 2; Condenser 2 connects evaporimeter 3; Described low-pressure absorption device 4 is closed container, and an end connects evaporimeter 3, one ends and connects respectively intermediate heat exchanger 5 and circulating pump 6; Interconnection between described intermediate heat exchanger 5 and the circulating pump 6, intermediate heat exchanger 5 is connected with hp heat exchanger 1; Be provided with liquid reservoir 7, filter 8 and choke valve 9 between described condenser 2 and the evaporimeter 3; Be provided with filter 8 and choke valve 9 between described low-pressure absorption device 4 and the intermediate heat exchanger 5; But the exhaust outlet of described hp heat exchanger 1 one end setting combustion gas.
When system moved, at first engine waste heat was carried out heat exchange with low-pressure, liquid refrigerant in hp heat exchanger 1, makes it to become the high pressure-temperature vaporized refrigerant; Vaporized refrigerant enters condenser 2 to carry out heat release cooling and goes into liquid refrigerant; To evaporimeter 3 feed flows, liquid refrigerant is at evaporimeter 3 interior endothermic gasifications through choke valve 9 for liquid refrigerant, and cold and hot exchange is constantly carried out with the interior air of car in evaporimeter 3 surfaces, reduces the temperature of interior space; Liquid refrigerant after the heat absorption vaporization becomes low-pressure low-temperature steam and enters low-pressure absorption device 4; Then after the low temperature liquid refrigerant cools that intermediate heat exchanger 5 bypasses are come, become the low-pressure low-temperature liquid refrigerant to be fed to through circulating pump and carry out heat exchange in the hp heat exchanger 1, so constantly circulation finally comes to lowering the temperature in the car by evaporimeter 3 and ventilation unit.
