A vehicle air conditioning system

Abstract

The invention belongs to the field of automobile air conditioners and particularly relates to an air conditioning system capable of detecting poisonous and harmful gas in air and automatically controlling and adjusting the air volume. The vehicle air conditioning system comprises an air inlet pipe, an air detection device, an air conveying device, an air inlet device, a filter device, a display device, a passenger detection device and a vehicle-mounted computer control device which is in data connection with the air detection device, the air conveying device, the air inlet device, the filter device, the display device and the passenger detection device, sends out a control instruction and further controls automatic switching between air inner circulation and outer circulation.

Description

technical field [0001] The invention belongs to the field of automobile air-conditioning, and in particular relates to an air-conditioning system capable of keeping the air in the vehicle clean and at a suitable temperature and air volume. Background technique [0002] With the continuous development of science and technology, the gradual improvement of the economic level, and the continuous improvement of people's material living standards, the requirements for the environment in the car are getting higher and higher. People's requirements and expectations for their daily life and the quality of the air environment in the car is constantly improving. Cars are the basic means of transportation for people, and they are used every day. The damage to human health caused by air pollution in cars has attracted more and more attention. As our country continues to promote the industrialization process, the surrounding environment of urban roads has changed greatly, and the frequen...

Problems solved by technology

As our country continues to promote the industrialization process, the surrounding environment of urban roads has changed greatly, and the frequent occurrence of toxic and harmful gases has become an important hidden danger affecting people's physical and mental health, especially when driving or riding for a long time, and the internal circulation of air conditioners for a long time As a result, the air in the car deteriorates rapidly, and the driver and passengers will experience dizziness, nausea and other problems to varying degrees. More seriously, it will affect driving safety. The longer the time, the more obvious this phenomenon will be. The main reason is the waste and pollution inside and outside the car The gas accumulates in the car, and more importantly, there is a lack of circulating fresh gas. Moreover, when the vehicle is driving in a toxic and harmful gas environment, it is difficult for people to detect changes in the external air for a while, and the air intake device cannot be closed in time, resulting in toxic and harmful gases. Entering the car, causing the driver and passengers to inhale excessive toxic and harmful gases

[0003] In addition, a vehicle air-conditioning system that makes passengers comfortable requires not only clean air, but also an appropriate temperature inside the vehicle and a suitable blowing speed. Currently, the target temperature of the automatic air-conditioning system in the vehicle is mostly determined according to the temperature changes outside and inside the vehicle. The adjustment does not take into account the immediate body temperature and physical condition of the passengers. In addition, the air-conditioning speed is fixed in several gears, which cannot be automatically adjusted according to the changes in the body temperature of the passengers and the number of passengers, which will cause discomfort to the passengers. In some cases, such as sleep, sickness, etc., the target temperature and wind speed will easily make passengers catch a cold or cause other discomfort
