Detailed ways

As shown in Figure 1 and Figure 2, the wind in this device enters the evaporator along the volute from the side close to the passenger, and the warm air core and high-pressure PTC are located behind the evaporator. The left and right foot blowing air ducts are arranged on the left and right sides of the distribution box, and the rear blowing foot and rear blowing surface air ducts are arranged below.

This embodiment relates to the control method of the above-mentioned reversely arranged air conditioning system, including multiple modes, specifically:

①Single surface blowing mode: As shown in Figure 3, the front blowing surface damper 201 is opened, the defrosting damper 202 and the foot blowing damper 203 are closed, and the back blowing foot damper 209 is switched to the individual surface blowing mode; the fresh air passes through the evaporator Finally, because the other dampers are closed, the wind enters the cockpit from the blowing air duct.

② Combination mode of face blowing and foot blowing: as shown in Figure 4, the front face blowing damper 201 is opened, the defrosting damper 202 is closed, the foot blowing damper 203 is opened, and the back blowing foot and face blowing damper 209 is switched to the combination mode of blowing face and feet ; The fresh air enters the cockpit from the air duct blowing on the face and feet after passing through the evaporator.

③Separate foot blowing mode: as shown in Figure 5, the front blowing air damper 201 and defrosting damper 202 are closed, the foot air damper 203 is opened, and the rear air blowing air door 209 is switched to the individual foot blowing mode; the fresh air passes through the evaporator Then enter the cockpit from the foot duct.

④ Combined mode of foot blowing and defogging: as shown in Figure 6, the front row face blowing damper 201 is closed, the defrosting damper 202 is half opened, the foot blowing damper 203 is opened, the front temperature damper 204 and the rear temperature damper 208 are opened and switched to warm. In the wind mode, after blowing the feet, the rear blowing surface damper 209 is switched to the sole blowing foot mode; after the fresh air passes through the evaporator, it continues to pass through the warm air core and the high-pressure PTC, and enters the cockpit from the defrosting air duct and the foot blowing air duct respectively.

⑤Individual defrosting mode: the front air damper 201 and the foot damper 203 are closed, the defrosting damper 202 is fully opened, the front temperature damper 204 and the rear temperature damper 208 are opened, switch to the warm air mode, and the feet are blown and the face is blown The damper 209 is closed; the fresh air sequentially passes through the evaporator and the warm air core along the flow path and from the defrosting tuyere, thereby achieving the purpose of defrosting.

The above specific implementation can be partially adjusted in different ways by those skilled in the art without departing from the principle and purpose of the present invention. The scope of protection of the present invention is subject to the claims and is not limited by the above specific implementation. Each implementation within the scope is bound by the invention.
