[0002] At present, the air conditioning structure of a car is equipped with an external circulation and an internal circulation. Generally, the external circulation is turned on in the heating mode, and the dry and cold air outside is used to reduce the risk of fogging of the whole vehicle, but it will lead to an increase in energy consumption; the internal circulation is turned on in the cooling mode, and long-term internal circulation will lead to less oxygen in the car and increased carbon dioxide concentration, which is not conducive to human health. Therefore, it is necessary to design a double-layer flow air conditioner. By adjusting the mixed air ratio of the internal and external air intakes, it can not only provide enough dry and cold fresh air to avoid fogging of the whole vehicle, but also fully realize the recycling and reuse of the hot air in the car, and achieve a better energy saving effect. However, the existing double-layer flow air conditioner has a high blowby rate, which leads to a high humidity in the defrost air outlet of the whole vehicle, which will cause the risk of fogging; and although increasing the amount of external air can reduce the risk of fogging, the energy consumption of the whole vehicle is not reduced.

[0059] In this example, when the ambient temperature is lower than 15°C, the air conditioning structure of the car turns on the heating mode and is in the heating condition. The blowing mode of the double-flow air conditioner is the foot-blowing defrosting mode or the foot-blowing mode, the external air inlet 5 is opened, and the two internal air inlets 6 are closed; the dry and cold air outside the car and the humid and hot air inside the car are sucked into the first flow channel cavity 101 and the second flow channel cavity 102 by the blower assembly 8 respectively, and the dust particles in the air are filtered through the first filter 9 and the second filter 10 to provide clean air for the passenger compartment; a blower ventilation cover 82 is installed on the blower flange 81, which can guide part of the air into the blower flange 81 to dissipate heat from the blower flange 81; the humid and hot air inside the car and the dry and cold air outside the car The evaporator core 11 does not perform cooling; the hot and humid air inside the vehicle and the dry and cold air outside the vehicle pass through the heater core 12, and the heater core 12 performs heating. At this time, the hot and humid air inside the vehicle is at a higher temperature, and the dry and cold air outside the vehicle is at a lower temperature. The hot and humid air inside the vehicle participates less in heat exchange, which can achieve energy-saving effects; the heated dry and cold air outside the vehicle is blown out through the defrost air outlet 32 to defrost and defog the front windshield of the entire vehicle; the heated hot and humid air inside the vehicle is blown out through the first foot blowing air outlet 41 and the second foot blowing air outlet 43 to heat the passenger compartment; the first partition 21, the second partition 22 and the third partition 23 are distributed in a stepped manner, and the gas pressure of the first flow channel cavity 101 is greater than the gas pressure of the second flow channel cavity 102; its principle formula is as follows:
