Automobile environment-friendly air conditioning system based on PM2.5 (Particulate Matter) monitoring and control method

Abstract

The invention discloses an automobile environment-friendly air conditioning system based on PM2.5 (Particulate Matter) monitoring, comprising a vehicular air conditioner body, wherein the vehicular air conditioner body comprises an air blower and a circulating air gate. The vehicular environment-friendly air conditioning system is characterized by further comprising a PM2.5 sensor and a control unit, wherein the control unit is connected with the air blower and is used for controlling the air quantity of the air blower; the control unit is connected with the circulating air gate and is used for controlling the circulating air gate to switch between inner circulation and outer circulation; the PM2.5 sensor is arranged on an air conditioner gas flow line; the control unit is connected with the PM2.5 sensor. According to the automobile environment-friendly air conditioning system based on PM2.5 monitoring, when the circulating air gate is in the outer circulation and the PM2.5 sensor monitors that PM2.5 is higher than a set value, the control unit controls the circulating air gate to switch into the inner circulation from the outer circulation, so that air pollution source is cut off, and the control unit controls a speed regulating module to increase the air quantity of the air blower, therefore in-vehicle air is circulated, and an air purification purpose is achieved.

Description

technical field [0001] The invention relates to a vehicle air conditioning system, in particular to a vehicle environmental protection air conditioning system based on PM2.5 monitoring. Background technique [0002] At present, as people spend more and more time in the car, the environment in the car is getting more and more attention, especially in recent years, there are more and more PM2.5 particles in the air, and under high temperature conditions, the car interior There will be more harmful gases such as formaldehyde and benzene, which seriously threaten human health. However, the current car air conditioners on the market can only filter some ordinary dust and do not have the function of air purification. [0003] Since the existing ordinary air conditioners do not have the function of air purification, people can only passively absorb harmful gases such as CO, sulfur dioxide and other sulfides in the air, and fine particles such as PM2.5 in the air cannot be removed. ...

Problems solved by technology

[0003] Since the existing ordinary air conditioners do not have the function of air purification, people can only passively absorb harmful gases such as CO, sulfur dioxide and other sulfides in the air, and fine particles such as PM2.5 in the air cannot be removed. Health, especially the harm to infants and young children is even greater
