Background technology
For middle automobile with small output volumn, mostly adopt non-self-contained air-conditioning unit at present, drive by engine power output shaft; For big discharge capacity automobile, then mostly adopt self-contained air-conditioning unit, drive by an other cover auxiliary power unit.Quovis modo, air conditioning for automobiles all adopts the vapor compression refrigeration technology both at home and abroad.This refrigeration modes is to be cost with consumption of engine power, also will satisfy the requirement of the working medium feature of environmental protection simultaneously.
Current, how a lot of in the world countries all utilize the energy of the used heat of automobile engine as refrigerating plant in research.The present invention is the reverse-bootstrap air circulation refrigeration system that drives with internal combustion engine waste gas energy, utilize this no any harm of air, cheap refrigeration working medium, by the thermodynamic cycle mode of particular design, under the prerequisite that reaches the refrigeration requirement, do not influence the dynamic property of engine again substantially.Be applicable to air conditioning for automobiles etc.
Summary of the invention
A kind of reverse-bootstrap air circulation refrigeration system that drives with internal combustion engine waste gas energy is made up of integrated four-wheel-type turbocharging-refrigerator or two turbocharger, heat exchanger, blower fan, proportional dump valve, jet pump, automatically controlled by-passing valve, CPU operating mode controller and signal transducer and temperature sensors etc.
The waste gas that this system discharges with the internal combustion engine manifold is power, adopts the reverse-bootstrap air cycle refrigeration, and the high temperature and high pressure gas part that discharge the back of boosting minimizes the consumption of wasted energy for engine replenishes the exhaust gas driven energy; Another part adopts in good time control system to the little supercharging of engine after lowering the temperature, and remedies the power loss that engine is produced because of after the insertion turbocharger, can suppress exhaust noise again simultaneously.This technology has energy-conservation and environmental protection two big advantages, is applicable to the exhaust energy of the internal combustion engine energy as refrigeration air-conditioner, as automobile etc.
The specific embodiment
1 one kinds of reverse-bootstrap air circulation refrigeration system schematic diagrams that drive with internal combustion engine waste gas energy of accompanying drawing.
The reverse-bootstrap air circulation refrigeration system schematic diagram of accompanying drawing 2-two turbocharger series connection.
System is designed to, and the power turbine (5) that has automatically controlled by-passing valve (3) is by engine (1) exhaust gas drive, and the waste gas of discharge is arranged to atmospheric environment by muffler (4).Power turbine (5) drives coaxial four-wheel-type turbocharging-refrigerator (TCT) rotation, forms basic reverse-bootstrap air circulation refrigeration system with heat exchanger (12) and axial flow blower (13).During refrigeration, by regulating the aperture of automatically controlled by-passing valve (3), control the rotating speed of turbocharging-refrigerator (TCT), thus, can prevent engine (1) when rotating speed is low, avoid because of inserting the pumping work " vexed car " that turbocharger (TCT) back increases engine (1) piston; When not freezing, by automatically controlled by-passing valve (3) to discharge bypass.Refrigeration system is provided with temperature sensor (11) and temperature indicator (10), forms the temperature adjusting of refrigeration system with air blast (9) and automatically controlled by-passing valve (3) four.Axial flow blower (13) is used for overcoming the resistance of heat exchanger (12) in the reverse-bootstrap refrigerating circuit and pipe-line system and decreases, to improve refrigerating capacity.
After the refrigeration, through the high temperature and high pressure gas that two-stage is boosted and discharged, a part is that engine (1) replenishes the exhaust gas driven energy by jet pump (2), wasted energy is consumed minimize; Another part is gone into the atmosphere through empty filter (18) through charge air cooler (14), proportional dump valve (17), jet pump (19) injection, synergy by signal transducer (15), CPU operating mode controller (16) and proportional dump valve (17), to the little supercharging of engine (1), remedy because of inserting the power loss that turbocharger (TCT) back produces engine (1) in good time; The two-way confined gas feeds back to engine (1), suppresses the exhaust noise of compressor (6).
One end of four-wheel-type turbocharging-refrigerator (TCT) is power turbine (5), and the other end is refrigeration turbine (8), and the centre is two stage compressor (6,7) series connection, Driven by Coaxial.Middle two stage compressor (6,7) can be the combination of two-stage radial-flow compressor, also can be primary axis flow air compressor and one-level footpath flow air compressor and combines.Four-wheel-type turbocharging-refrigerator (TCT) also can adopt two turbocharger (A, B) tandem compound to form.
Jet pump (2,19) is the working gas that will have certain pressure when spraying with certain speed by nozzle, because the horizontal turbulent fluctuation diffusion of jet particle is taken away the air in the suction line, forms negative pressure in the pipe, sucks and is inhaled fluid.Therefore, after the fluid of two kinds of different pressures and flow can being confluxed by designing requirement, enter system works with pressure and the flow of setting.
