System used for calculating service life of cabin air filter and calculation method thereof

Abstract

The invention relates to a system used for calculating the service life of a cabin air filter and a calculation method thereof. The system comprises an air conditioner controller used for obtaining different working condition parameters of the cabin air filter. The air conditioner controller is connected with an air conditioner cabinet, a humidity sensor, an ambient temperature sensor, an air quality sensor and a gateway control unit. The cabin air filter, an air blower and an internal and external circulation damper are arranged in the air conditioner cabinet. The air conditioner controller obtains parameters including the starting time of the air blower, the air conditioner external circulation time, the time of various environment working conditions and the mileage of a vehicle. According to the system used for calculating the service life of the cabin air filter and the calculation method thereof, the service lives of cabin air filters can be calculated according to information including vehicle using environments, using road conditions, vehicle using frequencies, ambient temperatures, ambient humidity and the like of different users, the users are informed in advance and can replace the cabin air filters in time, accordingly the air conditioning effects and the good in-vehicle air quality are guaranteed, and the situation that frequent replacing increases the maintenance cost is also avoided.

Description

technical field [0001] The invention relates to the technical field of automobile air-conditioning systems, in particular to a system for calculating the service life of an air-conditioning filter and a calculation method thereof. Background technique [0002] The air conditioner filter, commonly known as the pollen filter, is made of an environmentally friendly filter material after processing and folding, and is generally installed in the lower glass compartment in front of the passenger compartment of the car. The main function of the car air conditioner filter is to filter the impurities, tiny particles, pollen, bacteria, industrial waste gas and dust contained in the air entering the car from the outside to prevent such substances from entering the car. A good performance automotive cabin air filter can provide a good air environment in the car and protect the health of the people in the car. Clean and replace the cabin air filter during use. If it is not replaced for ...

AI Technical Summary

Problems solved by technology

Clean and replace the cabin air filter during use. If it is not replaced for a long time, it will affect the air conditioning effect, breed bacteria, and produce peculiar smells, etc., which will affect the air quality in the car and human health; Maintenance costs will increase significantly

[0003] At present, due to different conditions such as car environment, car frequency, and road conditions, the life of the air conditioner filter will also vary greatly. OEMs or 4S shops cannot give the exact time to replace the air conditioner filter. Only check or suggest the approximate time or mileage when the vehicle is maintained, which makes it difficult to ensure the air conditioning effect and the health of the occupants in the vehicle
