AQS (Air Quality System) implementing method and system applied to automobile afterloading modification

Abstract

The invention provides an AQS (Air Quality System) implementing system applied to automobile afterloading modification, comprising a harmful gas detector and an internal and external circulating throttle controller of an air-conditioning and ventilation system, wherein the harmful gas detector and the internal and external circulating throttle controller are sequentially connected, the harmful gas detector is arranged at an air-conditioning air outlet inside an automobile in a built-out way and comprises a gas sensor which is used for detecting the air quality inside the automobile; the internal and external circulating throttle controller of the air-conditioning and ventilation system comprises a throttle switch which is connected with an internal and external circulating manual switch of an original air-conditioning control panel system, and the internal and external circulating manual switch is controlled according to the detection result of the gas sensor so as to regulate the on-off of an air-conditioning throttle. The AQS implementing system applied to the automobile afterloading modification just needs to be arranged at the automobile air-conditioning air outlet in a built-out or built-in way, the throttle switch is connected with the internal and external circulating manual switch, and the internal and external circulation of an automobile air conditioner can be automatically switched according to the harmful gas content.

Description

technical field [0001] The present invention relates to an air quality control system, in particular to an AQS (Air quality control system, air quality control system) implementation method and system applied to automobile aftermarket. Background technique [0002] Scientific analysis shows that automobile exhaust contains hundreds of different compounds, and the emissions of automobile exhaust are mainly hydrocarbon compounds, the main components of which are CO 2 , H 2 O, N 2 , HC, Nx, HC means unburned hydrogen. Among them, the harmful components restricted by automobile emission regulations are CO, NOx, and HC. [0003] CO is highly toxic, and hemoglobin in the blood has a higher affinity for CO than for oxygen. The generated carbon monoxide hemoglobin destroys the oxygen transport capacity of the blood, makes people hypoxic, and can lead to shock and death in severe cases. [0004] HC includes unburned and incompletely burned fuel oil, lubricating oil and its crack...

AI Technical Summary

Problems solved by technology

[0006] Automobile exhaust has brought a lot of harm to people's daily life, especially car drivers often have such troubles. When the car air conditioner adopts external cycle operation, it often has to be exhausted due to the poor air quality outside the car (such as when waiting for a red light). Manually switch the car air conditioner to internal circulation to ensure the air environment in the car, and long-term internal circulation operation will cause the carbon dioxide content in the car to increase and the oxygen content to decrease, which will also have adverse effects on the human body
