Vehicle HVAC (high voltage alternating current) air inlet system and control method thereof

Abstract

The invention aims at providing a vehicle HVAC (high voltage alternating current) air inlet system and a control method thereof; the system can be used for effectively reducing the entry of the external dust, reducing the harmful gas volatilized by interior ornaments in a vehicle, and greatly improving the comfort level of the vehicle. The vehicle HVAC air inlet system comprises an HVAC air inlet, an inner-outer circulation control air door, a servo motor for driving the inner-outer circulation control air door, and a control unit; the HVAC air inlet comprises an outer circulation air inlet and an inner circulation air inlet; the inner-outer circulation control air door is arranged at the inner circulation air inlet or the outer circulation air inlet; and the control unit is connected with the servo motor. The vehicle HVAC air inlet system is characterized in that the control unit is respectively connected with an in-vehicle air quality sensor and an in-vehicle temperature sensor which are mounted in the vehicle as well as an out-vehicle air quality sensor and an out-vehicle temperature sensor which are mounted out the vehicle. The vehicle HVAC air inlet system is low in cost, and the control method thereof is easy to realize and can meet the requirements of human health and comfort level.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to an automobile HVAC air intake system and a control method thereof. Background technique [0002] The interior space of the car is small and there are many members. The interior parts in the car will volatilize some harmful gases and the volatilization cycle is very long. In cold winter or hot weather, the windows are closed, so most of the harmful gases will be absorbed by passengers. The comfort is reduced and the body is hurt at the same time, so the air in the car is often renewed by means of external circulation. However, occasionally a large amount of dust enters the car when driving on the road, and pollen enters in spring, causing passengers to be allergic. Therefore be badly in need of a kind of more effective method for purifying the air in the car. Contents of the invention [0003] The purpose of the present invention is to propose an a...
