Automatic air renewal system and automatic air renewal method of automobile air conditioner

Abstract

The invention relates to an automatic air renewal system of an automobile air conditioner, belonging to the technical field of automobile air renewal systems. The automatic air renewal system comprises a control device and a detection device. The detection device is connected with the control device through a data line. The automatic air renewal system is characterized in that the control device comprises a microprocessor, an air conditioner automatic control module and a monitoring module, wherein the air conditioner automatic control module and the monitoring module are connected with the microprocessor; and the detection device comprises a multi-infrared gas concentration monitoring module, an altitude monitoring module and a pressure value monitoring module. The automatic air renewal system of the automobile air conditioner has the beneficial effect that the internal and external circulating systems of an automobile are selectively controlled by detecting the altitude of the position of the automobile, the internal and external pressure of the automobile and the internal and external gas concentration of the automobile in real time, so as to guarantee that the internal space of the automobile always has high-quality air and the life and property safety of a driver is protected.

Description

technical field [0001] The present invention and the technical field of automobile ventilation system, in particular, relate to a method for monitoring and analyzing the indoor and outdoor altitude, air pressure value, and gas composition in the automobile, under specific altitude and air pressure conditions, when certain people's body When the concentration of necessary gas is low enough to endanger human physical and mental health, the auto air conditioning automatic ventilation system can selectively and automatically drive the internal and external circulation system of the auto air conditioner for ventilation. Background technique [0002] With the rapid development of the national economy and the further improvement of people's living standards, cars have gradually entered the lives of more people. In the process of using cars, people will pay more attention to the safety, performance, luxury and comfort of cars. . However, another issue closely related to safety and ...

Problems solved by technology

However, another issue that is closely related to safety and health has been overlooked: the air quality in the small space of the car

[0003] To solve the above-mentioned safety and health problems caused by the air quality in the car, a relatively simple way is to open the external circulation system of the car air conditioner to bring fresh air into the car, but there will be two problems in this way: first, open the external circulation system of the air conditioner It is relatively energy-consuming, and the outer circulation cannot be turned on all the time. It should be turned on as needed to save energy; second, when the environment where the car is located is seriously polluted, the outer circulation will bring in fresh air while also bringing in the outside of the car. Exhaust gas is sucked into the car, which even makes the air quality in the car worse
