Vehicle air quality detection and purification control system and control method thereof

Abstract

The invention discloses a vehicle air quality detection and purification control system. An air blower is arranged on an air hundling unit. The air inlet of the air blower is connected with an inner and outer circulation air door. One air inlet of the inner and outer circulation air door communicates with the interior of a vehicle and the other air inlet of the inner and outer circulation air doorcommunicates with the exterior of the vehicle. An air outlet of the air blower is connected with an air channel by an evaporator and a heater. The vehicle is internally provided with a display moduleused for displaying the working condition of an air conditioner and a button module. A filter is arranged at the air inlet of the air blower. An outside PM 2.5 sensor and a vehicle exhaust sensor arearranged at the air inlet, communicating with the exterior of the vehicle, of the inner and outer circulation air door. An inside PM 2.5 sensor is arranged at the air inlet, communicating with the interior of the vehicle, of the inner and outer circulation air door. The inside and outside PM 2.5 sensors output induction signals to an air conditioner control module. A negative ion generator is arranged at the position, close to the air outlet, of the blowing face of the air channel. The air conditioner control module outputs the quantitative value of the interior and exterior of the vehicle tothe display module to display, and controls shift of the inner and outer circulation air door. The requirements to air quality detection and purification and intelligent control by the vehicle can befully met.

Description

technical field [0001] The invention relates to the field of automobile air-conditioning systems, in particular to a system for detecting and purifying the air quality of automobiles. Background technique [0002] In recent years, the air quality situation has been widely concerned and valued by people. According to the survey results, the air quality inside the car is one of the places where the air quality is quite bad, and the time people use the vehicle is getting longer and longer. The air quality in the car also puts forward more and higher requirements. [0003] In order to improve the air quality in the car, many after-installed air purifiers have appeared on the market. The common disadvantages of this type of air purifier are that the size of the filter is limited by the volume on the one hand, and the fan is relatively large. The small air volume is limited, which ultimately leads to a very limited purification effect. On the other hand, because it is an independ...

Problems solved by technology

[0003] In order to improve the air quality in the car, many after-installed air purifiers have appeared on the market. The common disadvantages of this type of air purifier are that the size of the filter is limited by the volume on the one hand, and the fan is relatively large. The small air volume is limited, which ultimately leads to a very limited purification effect. On the other hand, because it is an independent purifier, it cannot communicate with the outside environment when it is placed in the car, so it can only perform limited purification treatment on the air circulating in the car. The part of the purified harmful gas is powerless, so it can only be used as a further supplement to the purification function of the vehicle air conditioning system, and cannot be well coordinated and integrated with the air conditioning system

In addition, the quality of air purifiers used as after-installation varies, and the price is relatively high for users
