Air conditioner control device for automatically converting internal and external circulation of automobile

Abstract

The invention relates to an air conditioner control device for automatically converting internal and external circulation of an automobile. The invention aims to solve the problem that an automobile air conditioner cannot automatically switch internal and external circulation when passing in and out a tunnel in the prior art. The air conditioner control device comprises an automatic air conditioner control panel, and a temperature sensor, a vehicle speed sensor, a temperature actuator and a blower which are connected with the automatic air conditioner control panel; and the air conditioner control device also comprises an ambient light and sunshine sensing assembly, a mode actuator and an internal and external circulation actuator, wherein the ambient light and sunshine sensing assembly, the mode actuator and the internal and external circulation actuator are connected with the automatic air conditioner control panel respectively. When the automobile runs into the tunnel, internal and external circulation air doors of the air conditioner blower can adjust to the mode of the internal circulation automatically rather than by artificial control to ensure that air in the automobile cannot be influenced by adverse gases in the tunnel. The air conditioner control device is more favorable for body health and improves vehicle driving conditions.

Description

technical field [0001] The invention relates to the field of automobile manufacturing, and more specifically, the invention relates to an air-conditioning control device for automatically switching the internal and external cycles of the automobile air-conditioning in the air-intake mode. Background technique [0002] At present, the air quality in the tunnel is seriously polluted, and the air contains a large amount of toxic and harmful substances including carbon monoxide, nitrogen oxides, hydrocarbons, aldehydes, and particulate matter. This is because the road tunnel is a relatively closed space. The atmospheric diffusion process of the tunnel is limited, the vehicles in the tunnel travel slowly, the fuel combustion is insufficient, and the concentration of harmful substances in the exhaust gas emitted by the vehicles is also increased. If there is a traffic jam, it will be even worse. When the car is running normally, people generally turn on the external circulation m...
