The present invention is described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.
Specific structure is as shown in figs 1 to 6.
A kind of active ventilation and pressure release system provided in this embodiment includes: pressure relief device 100, for interior ventilation；Control
Device processed is controlled for adjusting to pressure relief device 100；Information adjusts 100 institute of pressure relief device to control device based on the received
The state at place.
In the optional technical solution of the present embodiment, control device includes air-conditioner controller 200, air-conditioner controller 200 with let out
Pressure device 100 connects, for controlling the opening and closing of pressure relief device 100.
When car needs to divulge information, control device then open according to actual needs by control pressure relief device 100, makes interior gas
Body can flow to outside vehicle, realize ventilation.To, the active ventilation and pressure release system change traditional passive pressure release mode (that is,
Car, which reaches, opens realization ventilation for relief valve after certain gas pressure), it has been effectively relieved and has been let out since interior gas is uncontrollable
The problem of leakage quantity leaks out heat or cold air and increases energy consumption, in turn, substantially increases drafting efficiency.
It should be noted that almost all of automobile has air-tightness problem at present, i.e., there are the feelings of certain positive pressure in the car
Under condition, has portion of air and fall from interior each hole, hole or various clearance leakages, this part is referred to as uncontrollable leakage
Amount, and more very much not controllable leak amount is bigger for positive pressure；It only can just rise when ventilation quantity is greater than positive pressure in leakage rate rear car, rise
Relief valve could be opened after to the design cracking pressure of relief valve, is just able to achieve the fresh air ventilation function of outer circulation air conditioning mode in this way
Energy.The fresh air sucked outside vehicle by air conditioner blower in this way, a part are uncontrollable leakage rates, and a part is controllable leak
Amount, be then a kind of waste without controllable leak amount, so, how to reduce uncontrollable leakage rate be improve drafting efficiency approach it
One.
It needs to be emphasized that, uncontrollable leakage rate is much not only to waste required when air blower ventilation herein
A part of power consumption, if it is winter heating operating condition, then what is wasted is heat of engine, because air is added by air conditioning warm air
Crew module is arrived after heat again, has taken away heat if this partial air leaks away, and heat is power consumption for engine, it is right
It is then power consumption for pure electric vehicle, then is continuation of the journey course.Certainly, the waste situation principle of cooling in summer operating condition is same.
The passive relief valve of existing machinery formula is the necessity for just being able to achieve available ventilation after car reaches certain positive pressure, to can not solve
The certainly above problem.
In view of the above-mentioned problems, active ventilation and pressure release system provided in this embodiment then can effectively solve the problem that above-mentioned technology is asked
Topic, which, which then can be switched to outer circulation in air-conditioning, has ventilation demand (passenger pushes gear
Outer circulation, air-conditioner controller 200 receive the information) while open, thus allow automobile external circulation air inlet and rear portion
Exhaust outlet is connected directly by crew module space, HVAC (air handling system) interior aeration structure, and the positive pressure of very little can be real
Existing available ventilation, greatly reduces positive pressure pressure required for mechanical relief valve is opened, and direct draught then means uncontrollable let out
The decline of leakage quantity, so that drafting efficiency be substantially improved.
Under general driving situation, has following demand and uses outer circulation ventilation function:
For the demand that occupant has a breath of fresh air, fresh air can be evenly distributed to vehicle to traditional relief valve after opening
Interior each occupant position can not carry out selective adjusting；And active ventilation and pressure release system then may be implemented to air flow method
Regulatory function.If right back seat does not have occupant, and fresh air flows through becomes waste here, this is can be by air-conditioning control
Device 200 processed closes the pressure relief device 100 at right rear portion, opens or increases the draught area of left side pressure relief device 100, make total ventilation quantity
It is unaffected, and guide the pressure relief device in fresh air occupant direction on the left of all flowing to after front-row occupant breathing point
100, make to be sucked in the fresh air that right side is flowed out and is slatterned by left side occupant originally, to improve the utilization of fresh air
Rate can then create the condition for reducing ventilation quantity, thereby reduce because of ventilation bring energy consumption (especially in winter or summer
The inside and outside temperature difference of vehicle it is very big in the case where, the power consumption of ventilation volume consumption is reduced under the premise of guaranteeing that car does not haze, and can be right
The continuation of the journey of new energy vehicle provides very big help), or make occupant's breathing more fresh in the case where total ventilation quantity is inconvenient
Air, to improve comfort.
In addition, air-conditioning is arranged to outer circulation mode and opens skylight by certain customers' habit, enable air to from outer circulation wind
Mouth enters, and providing ventilation is flowed out and passed through from air outlet, may be implemented to reach making for ventilation effect without opening air blower in this way
With mode, but this operating condition have the disadvantage that open skylight noise is larger, rain and snow weather it is inconvenient use, heel row occupant can not exhale
It is drawn onto fresh air (under the premise of not opening heel row window) etc..
In view of the above-mentioned problems, by active ventilation and pressure release system in the present embodiment, then it can be in the feelings for not opening skylight
It is realized under condition and is entered the wind by outer circulation and flowed out from air outlet, divulged information, examined by the outlet of pressure relief device 100 via behind crew module space
Consider ventilation effect, pressure relief device 100 can be arranged in tailstock portion, and designs in similar skylight structure, so, not
Ventilation had not only been realized in the case where starting air blower, but also be not turned on the noise of skylight and elimination to be influenced by weather, and can allow
Heel row occupant also breathes to fresh air.
By active ventilation and pressure release system in the present embodiment, the air conditioning for automobiles ventilation device of inside and outside device mixing can be cooperated
It uses, gas use ratio in more is realized, to achieve the purpose that energy-saving.
In pure electric vehicle vehicle, the winter heating energy consumption of air-conditioning system has accounted for the 30%- of pure electric vehicle gross energy
50%, i.e., many electric vehicles are not turned on the aircondition the 100km that can continue a journey in winter, in continuing a journey if opening traditional PTC heating air conditioning
Journey is reduced to 50-70km.
And the main reason for winter air-conditioning system energy consumption is the demand of heating demand and pre- Antifogging, frosting, and will be simultaneously
It realizes heating and prevents to haze, in the case where the function of frosting, existing electric vehicle is all using 100% outer circulation ventilation mode work
Make, and outer circulation air can be discharged after air-conditioning is heated by relief valve at once, also take away while heating in this way
A large amount of heat, these heats are all course continuation mileage for pure electric vehicle.
So a kind of air-conditioning system ventilation device of new interior outer gas mixing is developed, and will be widely applied to
In new energy vehicle, because it can realize heating and while pre- Antifogging, frosting function using the interior gas of a part of ratio,
But interior gas ratio will be strictly limited, because of the excessively high risk increase that will lead to aerosol, frosting of interior gas ratio, to influence to drive
Safety.The interior excessively high then outer circulation ventilation quantity decline of gas ratio, then positive pressure is difficult to set up the decline of outer circulation ventilation quantity, then can not be opened
Normal outer circulation ventilation function cannot be achieved in relief valve, to increase the risk of aerosol, frosting.If outer gas ratio increases,
Can establish the positive pressure that ventilation needs, but uncontrollable leakage rate brought to increase simultaneously, it is not necessary to draft loss and thermal losses
Increase.
In view of the above-mentioned problems, the active ventilation and pressure release system in the present embodiment can not need positive pressure or very little just
Ventilation function is realized under the premise of pressure, uncontrollable leakage rate is effectively reduced, then interior gas ratio can be substantially improved after calibration
Example and be not in aerosol, frost, can thus be greatly reduced the internal circulating load of outer circulation cold air, save energy consumption and increase
Add continuation of the journey.
In conclusion active ventilation and pressure release system provided in this embodiment, controls pressure relief device 100 by control device
It opens or closes in due course, instead of traditional mechanical passive relief valve, allows must have positive pressure and be just able to achieve the outer of ventilation and follow
Ring ventilation mode, which upgrades to, not to be needed the positive pressure of positive pressure or very little outer circulation ventilation function can be realized.
In the case where can be realized reduces positive pressure after ventilation, uncontrollable leakage caused by can effectively reducing because of positive pressure
Amount promotes drafting efficiency or reduces ventilation power consumption.
After reducing uncontrollable leakage rate, the heat or cooling capacity that uncontrollable leakage rate is taken away can also be reduced, to subtract
The energy loss of few dynamical system.
After realizing active control decompression function, air-flow trend can be adjusted according to the practical situation of taking of passenger, from
And it promotes ventilation utilization efficiency or promotes the comfort having a breath of fresh air.
After realizing active control decompression function, the ventilation function of skylight can partially be replaced (not start air blower
Under the premise of), it realizes than opening the lower noise of providing ventilation and weatherproof advantage, realizes than opening providing ventilation only
In the case where front-row occupant capable of being allowed to have a breath of fresh air, while the advantage of heel row occupant breathing to fresh air can be allowed (not open
Heel row window, because opening heel row window noise can become larger).
When the ventilation device mixed with interior outer gas is used cooperatively, uncontrollable leakage rate can be effectively reduced, can increase
Interior gas use ratio, to reduce energy loss.
