Description
Technical field
The present invention relates to a kind of method that automobile equal power device is driven using environmental energy (solar radiant heat).
Background technology
The efficiency high of environment motility automobile up to 80%, twice existing fossil fuel (petrol and diesel oil), it is electronic, pneumatic with
And other hybrid vehicles, this was sounded as Arabian Nights, because the energy conversion efficiency of all power set is all basic
It is determined that.However, this energy-efficient automobile of manufacture is not impossible, thermodynamics is not violated, increased energy comes from environment (too
Positive radiant heat).This point is understood it should be understood that heat pump operation principle.
Heat pump is a kind of unique using energy source pattern, with a small amount of electric energy as drive energy, can from low-temperature heat source into
Absorption low grade heat energy again is to high temperature heat source.Operation of heat pump is not conversion process of energy, not by the energy conversion efficiency limit
Limitation.Heat that the heat of heat pump manufacture is it to be carried from environment and consumed energy and.Environment temperature zero degrees celsius, heat pump system
Hot Energy Efficiency Ratio COP is 4, i.e., 3 parts come from environment in 4 parts of heats of generation, and 1 part from input electric energy.Another critical function of heat pump
For synchronous refrigeration heat, 1 times is improved while being equal to using cold and hot Energy Efficiency Ratio, claims cold and hot two-way efficiency.
Environmental energy amplification can be utilized to heat to fail to be used for power set all the time with the heat pump of refrigerating capacity.In recent years,
In CO 2 cross-critical kind of refrigeration cycle, for CO2Critical-temperature is low, and critical pressure is high, the big situation (dioxy of restriction loss
Change 31.1 DEG C of carbon critical-temperature, 7.3 MPas of pressure.- 78.5 DEG C of boiling point under -56.6 DEG C of three phase point, normal pressure), substituted with expanding machine
Expansion valve, has not only reclaimed 30% or so work done during compression (from the common energy of compressor and environment), and increases substantially
Heat pump refrigerating ability.In theory, the work(of expanding machine output is equal to the refrigerating capacity that system is increased newly, and the work(of output is more, working medium
Refrigerating capacity is stronger, temperature drop is bigger.For example, air from 0.6 MPa by expander to 0.1 MPa of theoretical temperature drop up to 80
DEG C -90 DEG C, there was only 1 DEG C by the expansion valve temperature drop that throttles, reason is the former output work.
Improving heat pump efficiency while supercritical carbon dioxide kind of refrigeration cycle output work with expanding machine turns into common recognition, this
Technology is applied to refrigerated energy-saving, and way is that expanding machine and compressor is coaxially connected to reclaim restriction loss.Overcritical dioxy
Temperature of Working can be dropped to -70 DEG C so that lower by changing carbon expander, and this low temperature cold can be as nested with ring
Border is the low-temperature heat source of the Organic Rankine Cycle of high temperature heat source.
The power cycle of environment motility automobile is neither power cycle, nor heat pump cycle.The same with heat pump, it can be from
Environment absorbs heat, and its most of energy comes from environment, and fraction comes from electric energy (compressor power consumption).The same with heat engine, it can be by
The thermal transition absorbed from the external world exports for work(.It absorbs heat cooling by evaporation as cooling using environment as high temperature heat source using working medium from environment
Medium.Temperature of Working need to only be compressed to cooling medium and releasing for working medium latent heat can be achieved on ambient temperature by compressor
Put, so as to reduce compressor power consumption.
Environment motility automobilism principle is close with Pneumatic automobile, both by compressed gas puffing work done.
Pneumatic automobile promotes piston movement to provide power for automobile, after all using compressed air as power source by expansion of compressed gas
Pneumatic automobile is electric automobile, because air compression fully relies on electric power.The Pneumatic automobile gas storage tankage size of 200 kilometers of stroke
300 liters, 30 MPas of pressure, the operating pressure of air motor import are generally 1 MPa, 0.2 MPa of outlet pressure.
Piston-mode motor is used Pneumatic automobile more.Because if expansion of compressed gas process can obtain energy from environment,
The exergy efficiencyX of compressed gas can just be improved.The heat absorbed from environment is more, closer to preferable Isothermal Condition.And it is adiabatic swollen
Swollen working medium can not be from external world's heat absorption.
The content of the invention
The power cycle of environment motility automobile includes evaporation, condensation, expansion, whole compression process.Liquid carbon dioxide work
Matter obtains interior energy from environment heat absorption by evaporator and evaporated, and evaporates the cold (cooling by evaporation) produced as cooling medium and enters cold
Condenser.Working medium interior energy is converted to work(through air motor or expanding machine.The working medium that acting releases interior energy is completed, is exchanged heat with environment
Enter condenser to cooling by evaporation exothermic condensation through compressor compresses after rising again.The condensed expanded machine of high-pressure liquid working medium
(valve) decompression is low temperature, low pressure moist steam enters evaporator, starts new round circulation.
Due to a variety of causes, real process ideal isothermal expansion can not be realized.The limited volume of cylinder of piston-mode motor
And heat-exchange time have impact on expanding gas and be absorbed heat from environment, cause as little as -15 degrees Celsius of low temperature exhaust gas to discharge.Residual voltage and cold
The air motor loss in efficiency that amount discharge is caused is up to more than 40%.
It is a feasible selection to substitute air motor with expanding machine.The inferior position that adiabatic expansion can not absorb heat from the external world can
To obtain part compensation, specific method is that the low temperature for producing expander is used as nested having by high temperature heat source of environment
The low-temperature heat source of machine rankine cycle.Environment motility automobile expander nesting Organic Rankine Cycle dry run process is shown in attached
Fig. 1.
Preferable adiabatic process actually can not equally be realized.Select piston type pneumatic engine also or expanding machine will consider
Efficiency, reliability and economic index.No matter piston-mode motor or expanding machine are used, environment motility automobile all exists
COP is run on the basis of being more than 1, and make use of cold and hot two-way efficiency (refrigerant from environment heat absorption be the increased suction of environment
Heat energy power, is shown in air-conditioning work principle).
The determination of working medium evaporating temperature will not only consider environment temperature, it is also contemplated that bloating plant bearing capacity, expansion ratio
And because of the too high and issuable throttling of evaporating pressure or loss in efficiency.0 DEG C of evaporating temperature, the corresponding pressure of carbon dioxide is
3.49 MPas, be nearly 3.5 times of piston type pneumatic engine inlet pressure, and -20 DEG C of evaporating temperature is 1.97 MPas, still 2 times
The operating pressure of air powered engine.In view of heat transfer temperature difference, environment motility automobile can be at minimum -20 DEG C so that lower
Run under environment, environment temperature is too low to switch to electric-only mode.
The fundamental difference of environment motility automobile and Pneumatic automobile is that the former uses low boiling working fluid, can be inhaled from environment
Heat obtains energy, and the latter is using air as medium, and gas compression fully relies on electric energy.The former is that closed circulation does not have any discharge,
The latter discharges cold air.The former is not limited by energy conversion, but affected by environment.The latter is limited by energy conversion, substantially not by
Ambient influnence.
Brief description of the drawings
