Description
Technical field
The automobile that the present invention relates to a kind of air conditioning for automobiles filter replacement based reminding method, air conditioning for automobiles filter replacement alarm set, adopts the automotive air-conditioning system of this alarm set and adopt this automotive air-conditioning system.
Background technology
Automobile is as a kind of modern means of communication, and is inseparable with people's life.According to statistics, the annual time that the modern city people spends in automobile is 730 hours, so the air quality in the automobile has very big influence to the level of comfort and the health status of passenger.
Automotive air-conditioning system is the abbreviation of automobile air-condition system, promptly adopts the method for artificial cooling and heating, regulates parameter indexs such as the interior temperature of car, humidity, air-flow velocity, cleanliness, thereby creates the environment inside car of fresh and comfortable for people.Because contain impurity usually in the general air, it comprises finely ground particles, pollen, bacterium, industrial gaseous waste and dust etc., thereby disposes air-conditioning filter cleaner in the automotive air-conditioning system; Contain filter core in the air-conditioning filter cleaner; The main effect of filter core promptly is, filters the air that gets into interior from the external world, thereby prevents that above-mentioned impurity from getting into a/c system and getting into the compartment; The cleanliness of air in the car is improved; Give simultaneously and drive the indoor fresh air that provides, good air ambient is provided for the interior passenger of car, the assurance occupant's is healthy.
At present, in air conditioning for automobiles, the air-conditioning filter cleaner filter core generally is installed near the admission port of automotive air-conditioning system, and the front side of blowing engine in the just whole airflow field is used for filtered air to guarantee the air quality in the passenger compartment.No matter the mode of operation of blowing engine is new wind pattern (air from outside to inside) or interior circulation pattern (air is in), the air of blowing engine wind outlet all need filter through air-conditioning filter cleaner.After a/c system uses a period of time; It is regulated efficient and will reduce; This moment, considered was changed air-conditioning filter cleaner; More simply and cheaply be the filter core of only changing in the air-conditioning filter cleaner, easy for describing, will change air-conditioning filter cleaner among this paper and only change all unified replacing air-conditioning filter cleaner that is called of filter core in the air-conditioning filter cleaner.
In the prior art; The general time-based maintenance mode that adopts is changed air-conditioning filter cleaner; Promptly determine whether changing air-conditioning filter cleaner according to vehicle driving mileage or running time; For reminding the user in time to change air-conditioning filter cleaner, some middle-and-high-ranking configuration of automobiles have " replacing air-conditioning filter cleaner " alarm set automatically.
Application number is to disclose a kind of " reminding device for replacing air-conditioning filter cleaner " in the Chinese patent of 200810201863.X; The add up work-hours of unit accumulative total air-conditioning filter cleaner of this device passage period; This work-hours was compared with the reminder time of presetting, exported " replacing air-conditioning filter cleaner " information to the user by Tip element.In addition; Application number is to disclose a kind of " reminding device for replacing air-conditioning filter cleaner " in 200920070607.1 the Chinese patent; This device is through the add up travelled distance of unit accumulative total vehicle of mileage; This travelled distance is compared with the prompting mileage that presets, exported " replacing air-conditioning filter cleaner " information to the user by Tip element.Above-mentioned two patents are all through comparing or remind mileage and travelled distance to compare reminder time of presetting and running time; Point out the user to change air-conditioning filter cleaner; For the user changes air-conditioning filter cleaner reference timely is provided, but the substitute mode that these two kinds of alarm sets adopt still belongs to the time-based maintenance substitute mode.
In real life; Because there are very big-difference in the environment for use of different vehicle and the Occupation coefficient of automotive air-conditioning system; Make that also there is very big-difference in the extent of deterioration of air-conditioning filter cleaner in the different vehicle; By existing time-based maintenance mode or according to preset travelled distance or running time reminding user to replace air-conditioning filter cleaner, often exist replacing to judge inaccurate situation, often cause too early or cross replacing in evening air-conditioning filter cleaner; If change too early then cause the wasting of resources easily, make increasing of user with the car cost; Spend evening and change the regulating effect that then can influence a/c system, cause air quality decline in the car, reduce the comfort level that the user takes, bring healthy hidden danger.Therefore, change the mode that air-conditioning filter cleaner is changed of available technology adopting, have positive meaning for the needs that satisfy the market user.
Summary of the invention
Technical matters to be solved by this invention is the above-mentioned deficiency that the replacing to air-conditioning filter cleaner in the prior art exists, and providing a kind of can provide air conditioning for automobiles filter replacement based reminding method, the air conditioning for automobiles filter replacement alarm set of changing air-conditioning filter cleaner information and adopt the automotive air-conditioning system of this alarm set and adopt the automobile of this automotive air-conditioning system for the user accurately, timely.
Because when automotive air-conditioning system moves down at AD HOC (for example refrigeration under economic model, fitness mode, the uniform temperature or heating mode etc.); Under the situation of other consumer current stabilizations in the automobile, the working current value of blowing engine is a relatively-stationary value.Research shows that when motoring condition one timing, the relation of the working current of blowing engine and air-conditioning filter cleaner clean-up performance is: the air-conditioning filter cleaner clean-up performance is more little; Then the static pressure of blowing engine is big more, and air quantity is more little, and power is more little; Because operational voltage value is generally definite value in blowing engine; So blower power is more little, its working current value is more little, and the relation between blowing engine air quantity, static pressure Ps and the electric current I three is as shown in Figure 1.Hence one can see that, regularly detects by the operating current to air blast, for example whenever detects once at a distance from a few minutes, can accurately judge the clean-up performance of air-conditioning filter cleaner according to the size of working current value.Under the situation that the general replacement standard of changing according to the air-conditioning filter cleaner needs is judged; For an air-conditioning filter cleaner that meets the general replacement standard; When it uses in automotive air-conditioning system; Can detect obtain blowing engine the working current value of different operational tapses (wherein a plurality of different adjustment gears of having of blowing engine according to blowing engine different working pattern or under certain mode of operation its watt level distinguish), the working current that detects the blowing engine that obtains must be less than the running current of its pairing blowing engine at this operational taps.Because air blast is to change among a small circle at one at the running current of each different operational tapses based on the different situations in the reality, thereby can set a current attenuation allowed band value, becomes more rationally with more accurate so that replacing is judged.Certainly, because possibly there is the standard of different replacing air-conditioning filter cleaners in different users, also can combine user's actual conditions to set current damping allowed band value.
