Efficient fresh air filtering method and system for automobile air conditioner

Abstract

The invention relates to the field of efficient fresh air filtering for automobile air conditioners and discloses an efficient fresh air filtering method and system for an automobile air conditioner. The method and system can be used for efficiently filtering out fine particular matters and harmful matters from fresh air for an automobile. The method is characterized in that after foul air is efficiently filtered through an air filter which is connected with an air conditioner fresh air filtering system shell in a sealed manner via an efficient sealing device and a double efficient sealing device, clean air is fed into the automobile. Meanwhile, a turbulence equalizer is used, so that the filtering effect on ultrafine particle matters is improved; by detecting the difference of air pressures at the front end and the rear end of the air filter, the work state of a draught fan is controlled, the air volume is enabled to be constant, and the replacement of the air filter is promoted; and an intelligent harmful gas and substance detector detects the quality of air in the automobile, and the work state of the fresh air system can be automatically controlled. The efficient fresh air filtering method and system for the automobile air conditioner have the following remarkable advantages that no extra space in the automobile is occupied; the safety is achieved, and the attractiveness is not affected; secondary pollution of ozone is not generated; the service life of a filter screen is long; and the efficient fresh air filtering method and system for the automobile air conditioner are suitable for fresh air filtration of automobile air conditioners of any type.

Description

technical field [0001] The invention relates to the field of high-efficiency filtration of fresh air for vehicle air conditioners, and can be used for high-efficiency air filtration of fine particles and harmful substances in fresh air for vehicles. Background technique [0002] With the continuous increase of population density and economic development, the number of cars in large and medium-sized cities has risen rapidly. The quality of urban air has been declining in recent years. Especially on the roads where vehicles are intensively used in large and medium-sized cities, the content of fine particulate matter PM2.5 in vehicle exhaust, as well as harmful substances such as sulfur dioxide and nitrogen dioxide in the air continues to increase, seriously endangering the health of drivers and passengers. The fresh air filter of the current car air conditioner has a certain filtering ability for large particles, but cannot efficiently filter fine particles PM2.5 and harmful ...

AI Technical Summary

Problems solved by technology

The main problem of the current fresh air filter system for vehicle air conditioners is that the filter screen of the filter and the sealing of the whole system are not designed for fine particulate matter PM2.5 and harmful gas substances

Especially after the current car air conditioner filter is used for a period of time, as the filter is continuously blocked by particles, the pressure loss will increase accordingly. In this case, more dirty air will be filtered from the air filter and the fresh air of the car air conditioner. The gaps between the system housings pass through, resulting in a continuous reduction in the filtration efficiency of the entire system

At the same time, the fresh air filter system of the current car air conditioner cannot intelligently detect the pollution degree of the air in the car, and cannot further intelligently control the working status of the system

Although there is currently a way to install a car air purifier, most of the car air purifiers on the market will generate ozone and cause more serious secondary pollution. At the same time, due to the inability to carry out structural anchorage, it will also increase the possibility of people being injured by the car purifier in the event of a vehicle collision
