Universal vehicle heating ventilation air conditioning (HVAC) of three-compartment structure and control method thereof

[0038] This embodiment relates to a general-purpose three-compartment vehicle air conditioner HVAC, and its structural schematic diagram is as attached figure 1 , 2 As shown in and 3, it includes: the blast distribution box 1, the evaporation box 2 and the air inlet box 3 connected in sequence, and the connections are connected;

[0039] in,

[0040]--The blast distribution box 1 is a turbine-shaped structure, consisting of an upper casing of the blast distribution box, a lower casing of the blast distribution box, a front casing of the blast distribution box, a rear casing of the blast distribution box, and a blast distribution box. The left shell of the box is enveloped, and a blower, a motor and a mode distribution damper are arranged in it, and the motor drives the blower to run; the shell of the blowing distribution box 1 is provided with a single air outlet 4; the air outlet is in The upper shell of the blast distribution box, the lower shell of the blast distribution ...

[0050] This embodiment relates to a general vehicle air conditioner HVAC with a three-compartment structure, and the structure is the same as that in Embodiment 1.

[0051] This embodiment provides a control method for a general three-compartment vehicle air conditioner HVAC, including the following steps:

[0052] Step 1, when the air conditioner is in internal circulation or external circulation mode, fresh air enters the air intake box 3 from the internal circulation damper or the external circulation damper through the filter;

[0053] Step 2, the evaporator core or warm air core in the evaporator 2 turns on the cooling or heating mode to cool or heat the incoming fresh air;

[0054] Step 3, the blower in the blower distribution box 1 operates to blow air according to the selected damper mode, so as to promote the air circulation in the vehicle.
