Description
Technical Field
The invention relates to an air conditioner detection system, in particular to a portable detection system for the residual service life of an automobile air conditioner filter element and an air conditioner pipeline.
Background
With the social development, more and more automobiles enter families of common people, and the automobiles gradually become necessities for life. Along with the improvement of living standard of people, people have higher and higher requirements on the air quality of vehicles.
The air conditioner filter element of the automobile effectively filters and adsorbs air (pollen, dust, peculiar smell and the like) sucked by the automobile, thereby ensuring good air quality in the automobile. However, the air conditioner filter element has certain dust holding capacity and limit of dirt holding capacity, and the filtering efficiency of the air conditioner filter element is reduced while the air conditioner filter element filters the substances. When the temperature is reduced to a certain limit value, the filter element can not play the role of filtration and adsorption. The filter core is not changed in time at this time and can cause more secondary pollution, and filtration efficiency descends simultaneously and causes dust etc. to get into air conditioner pipeline and the evaporimeter of air conditioner, runs into moist environment such as evaporimeter surface or air conditioner pipe wall and easily goes mildy, breeds the bacterium, produces the peculiar smell, influences passenger's breathing health.
The air conditioner filter elements from different sources have larger filtering capacity difference, and the filtering capacity of the air conditioner filter elements cannot be really known by common consumers only by the propaganda filtering efficiency; the long purchase of the filter element does not mean that the filter element is dirty, and in places with good air, the dirty filter element is slow; the replacement of the air conditioner filter element on time cannot guarantee that the air conditioner pipeline is not dirty.
The current technical scheme is as follows: for example, by time conversion, observation of the use condition of the air blower, judgment through wind pressure judgment, judgment through the filtering time of the filter element, installation of a PM2.5 sensor in the air-conditioning pipeline and the like, the possibility of failure of the air-conditioning filter element is countervailed, and misjudgment cannot be avoided.
The time and the efficiency of the filter element are not in a simple linear relation, are influenced by the ambient temperature and humidity and the air quality, and are inaccurate by indirect judgment of time; the wind pressure of the air blower is judged in a mode, the influence factors are many and are not necessarily caused by the dirt of the filter element, and if large foreign matters such as dead leaves block the air inlet of the ventilation cover plate, the wind pressure of the air blower can be increased for a long time, so that the possibility of misjudgment is avoided; in the mode of judging the PM2.5 purification time through the air conditioner filter element, the time from an initial preset value (such as 100) to an end value (such as 50) is calibrated; if the time is longer than a certain value, starting reminding; however, the calibration time is actually influenced by the environmental conditions, for example, when PM2.5 outside the vehicle is 200, the interior of the vehicle may be maintained at 100 after being filtered by the filter element, so that the time for reducing the time from 100 to 50 is very long, but the filter element fails, dust contents PM10, PM2.5, PM1.0 and the like in different urban air are different, the filtering capacities and efficiencies of filter elements of different brands are different, and a vehicle owner cannot be forced to purchase the filter element of an original factory of the vehicle, so that the method is effective only under a specific working condition, and the remaining life of the universal filter element cannot be accurately detected.
Whether the air-conditioning pipeline is clean or not is generally judged by adopting a time, smell sense and telescopic camera, and the time and the cleanness of the air-conditioning pipeline have no linear relation; smelling the peculiar smell does not represent that the air conditioner pipeline is dirty, possibly because the air conditioner filter element is subjected to the peculiar smell caused by the moisture; looking directly through the camera, everyone understands the dirty differently, causes no unified standard.
In summary, it is necessary to provide a solution to solve the problem that the prior art cannot be based on the standard space in the vehicle and the stable detection environment; the residual service life of the filter element and whether the air-conditioning pipeline needs to be cleaned cannot be accurately and timely determined; the technical problem that can not be shown in clear datamation.
