Description
Technical field
The present invention relates to field of automobile air conditioner, in particular to a kind of automobile air conditioner inlet air system.
Background technology
Air conditioning for automobiles is for the temperature in automobile bodies, humidity, air cleanliness and air flow to be adjusted and controlled
In optimum state, comfortable seating environment is provided for occupant, reduces journey fatigue；Good condition of work is created for driver,
The ventilation unit to be played an important role to ensuring safe driving.Generally comprise refrigerating plant, heating installation and compound ventilation air-changing device.
Wherein, compound ventilation air-changing device is mainly used in controlling the interior circulation and outer circulation of automobile, and interior circulation refers to that air blower blows
The wind gone out only circulate in the car by portion, because no extraneous air participates in, has fuel-efficient, refrigeration（Heating）The advantages of fast, shortcoming are
It is unfavorable for the renewal of in-car air.Outer circulation refers to that air blower suction air outside car is blown into in-car.Advantage is to maintain in-car
The freshness of air, but excessive fuel consumption, refrigeration（Heating）Speed is slow.
Existing air-conditioning device, the control switched using an air door inner loop air inlet and external circulation air inlet
System, a kind of pattern in interior circulation or outer circulation can only be selected.When user is fixed on outer circulation for a long time, constantly have fresh
Air enters driver's cabin, and air quality is good, but the air-flow for participating in air-conditioning heat exchange is all from outside driver's cabin, and cooling in summer air-conditioning needs not
Disconnected that external high temperature gas is converted into cryogenic gas reduction driving indoor temperature, air conditioner load is big, and air-conditioning temperature-reducing speed declines, together
When the compressor of air conditioner working time it is elongated, the life-span declines, and winter heating air-conditioning needs that extraneous cryogenic gas constantly is converted into height
Wet body, which improves, drives indoor temperature, and air conditioner load is big, and air-conditioning heating rate declines, and driver's cabin heating is slow.
The content of the invention
For above-mentioned the deficiencies in the prior art, the technical problems to be solved by the invention are：How a kind of structure letter is provided
