Vehicle air purification system and in-vehicle air purification method

Abstract

The invention discloses a vehicle air purification system and an in-vehicle air purification method. The purification system comprises an in-vehicle oxygen content detection device, a PM2.5 sensor, an inner circulation air door, an outer circulation air door, an activated carbon filter element and a control device. When the vehicle air conditioning system is in an automatic adjusting state, and the oxygen content in the vehicle is lower than a standard value, the control device controls the inner circulation air door to be closed, controls the outer circulation air door to be opened and switches to an outer circulation state; when the oxygen content in the vehicle is normal, the control device controls opening and closing of the inner circulation air door and the outer circulation air door according to the PM2.5 value in the vehicle and the PM2.5 value outside the vehicle, and switching of the inner circulation state and the outer circulation state is achieved. According to the purification system and the purification method provided by the invention, the air quality in the vehicle is monitored and improved by comprehensively considering indexes of PM2.5 and oxygen content, so that the supply quantity of oxygen is ensured, the PM2.5 content is reduced, the level of a driving environment in the vehicle is improved, and sterilization and disinfection can be performed through the negative ion generator.

Description

technical field [0001] The invention belongs to the technical field of vehicle air conditioning function expansion, and in particular relates to a vehicle air purification system and a vehicle interior air purification method. Background technique [0002] Since the 21st century, my country's economy has been developing rapidly. With the rapid development of the economy, environmental problems have become more and more serious, and people have paid more and more attention to them. The quality of air has seriously affected people's health. In recent years, The PM2.5 value in the air is also included in the air quality assessment system. With the rapid development of the vehicle transportation industry, drivers have to persist in working in harsh air environments. In order to provide drivers with a good driving environment, the development of cab air purification systems has been put on the agenda. [0003] At present, vehicles generally use a filter structure for air purifica...

AI Technical Summary

Problems solved by technology

[0003] At present, vehicles generally use a filter structure for air purification, and there is a lack of methods for evaluating and purifying the overall air purification. Due to the advancement of vehicle sealing technology, the oxygen content of the air in the car is also an issue that is increasingly worthy of attention, and the oxygen content of the air is declining. Seriously affect the driving safety of the vehicle
