Air intake system for automobile air conditioner

Abstract

The invention discloses an air inlet system of an automobile air conditioner. The air inlet system comprises a shell body, wherein the shell body is provided with an inner circulating air inlet and an outer circulating air inlet, and is characterized in that the inner circulating air inlet is provided with a rotatable inner circulating air door in a matching manner and the rotatable inner circulating air door is used for controlling the opening and closing of the inner circulating air inlet; the outer circulating air inlet is provided with a rotatable outer circulating air door in the matching manner and the rotatable outer circulating air door is used for controlling the opening and closing of the outer circulating air inlet; the shell body is further provided with an air door driving mechanism; and the air door driving mechanism is connected with the inner circulating air door and the outer circulating air door respectively, so that the inner circulating air door and the outer circulating air door can be driven by the air door driving mechanism to rotate. The air inlet system of the automobile air conditioner has the advantages that the structure is simple and the air inlet system is convenient to mount and convenient to control; the energy consumption of the air conditioner can be reduced and the refrigeration and heating speeds are improved; the freshness of air in an automobile is increased and fatigues of a driver and passengers, caused by the fact that air is too turbid, are avoided; and the driving and taking comfort, the driving safety and the like can be easily improved.

Description

technical field [0001] The invention relates to the field of automobile air conditioners, in particular to an air intake system for automobile air conditioners. Background technique [0002] Automobile air conditioning is used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment to the best state, provide a comfortable riding environment for the occupants, reduce travel fatigue; create good working conditions for the driver, and A ventilation device that plays an important role in ensuring safe driving. Generally include refrigeration equipment, heating equipment and ventilation equipment. [0003] Among them, the ventilation device is mainly used to control the internal circulation and external circulation of the car. The internal circulation means that the wind blown by the blower only circulates inside the car. Since there is no external air involved, it has the advantages of fuel saving and fast cooling (heating). The dis...

Problems solved by technology

When the user is fixed in the external circulation for a long time, fresh air will continuously enter the cab, and the air quality is good, but the airflow participating in the heat exchange of the air conditioner comes from outside the cab. In summer, the cooling air conditioner needs to continuously convert the high-temperature gas from the outside into low-temperature gas to reduce the temperature inside the cab. , the load of the air conditioner is heavy, and the cooling rate of the air conditioner decreases. At the same time, the working time of the air conditioner compressor becomes longer and the service life decreases. In winter, the heating air conditioner needs to continuously convert the external low-temperature gas into high-temperature gas to increase the temperature in the cab. Cab heating is slow
