Automobile passenger compartment air conditioning apparatus based on air quality assessment and method thereof

Abstract

The invention discloses an automobile passenger compartment air conditioning apparatus based on air quality assessment and a method thereof. The apparatus comprises a temperature sensor, an air quality detector, a humidity sensor, an air purifier, an air blower, an electric valve and a microprocessor (MCU). The temperature sensor, the air quality detector, the humidity sensor and the air quality detector monitor the temperature, humidity and quality of air in a compartment in real time, and signals are sent to MCU, the MCU controls an electronic-control tee valve, the air blower and the electric valve according to the collected signals and the rules set in inner, so as to switch air circulation modes or air-flow channels. The apparatus can utilize the external environment to the most extent to maintain appropriate temperature and humidity of the air in the compartment and good air quality in an assisting manner, utilize a dehumidifier to effectively lower the air humidity in the compartment, utilize an air purifier to improve the air quality in the compartment in harsh environments, and the threat of life safety of passengers due to the deterioration of air quality in the compartment is prevented.

Description

technical field [0001] The invention relates to an air-conditioning device for an automobile passenger compartment based on air quality evaluation, and is a device for solving the problem of air quality deterioration in a vehicle compartment when the outside air quality changes greatly (such as driving in an urban area). Background technique [0002] The automotive air conditioning system is divided into internal circulation and external circulation air circulation modes. At present, it is generally believed that the internal circulation has the advantage of fast cooling (heating) and the disadvantage of being unfavorable for the renewal of the air in the car because there is no external ambient air to participate. External circulation, due to the participation of external ambient air, has the advantage of keeping the air in the car fresh and the disadvantage of slow cooling (heating) speed. The control of internal and external circulation in the prior art is also designed ...

AI Technical Summary

Problems solved by technology

[0003] At present, the internal and external circulation of the automotive air-conditioning system is still switched manually or semi-automatically, not according to the specific air conditions inside and outside the cabin, which causes the vehicle to turn on the internal or external circulation of the air-conditioning system by mistake under many specific conditions of use. Deterioration of air quality in the cabin

For example, when some cars turn on the cooling or heating cycle, in order to ensure the fresh air in the car, the external circulation mode of the air conditioner will be turned on for a while at regular intervals. Not only will it not improve the air quality in the car, but it will worsen it
