Embodiment 1
[0054] A distributed vehicle heating and air conditioning system, such as figure 1 , including integrated panel controller 101, distributed heating plate 102, glass defogging plate 103, ventilation channel 108, external circulation pipe 105, internal circulation pipe 106, air duct switching damper 107, air conditioning filter element 109, electric heater 110 , evaporator 111, blower 112, air duct temperature sensor 113, interior temperature sensor 114 and wiring harness 104;
[0055] Such as figure 2 and image 3 , the distributed heating plate 102 is used to realize heat supply output and output adjustment, and it is arranged at two or more positions inside the cab to realize heating of the legs, feet, and upper body of the driver and passengers;
[0056] Ventilation pipeline 108, external circulation pipeline 105, internal circulation pipeline 106, air duct switching damper 107, air conditioner filter element 109, electric heater 110, evaporator 111, blower 112, air duct ...
Embodiment 2
[0072] In the control method of the distributed automobile heating and air-conditioning system described in Embodiment 1, further, when the driver needs internal circulation, the position of the air duct switching damper 107 is switched to realize the conduction and external circulation of the internal circulation pipe 106 and the ventilation pipe 108 The pipeline 105 and the ventilation pipeline 108 are closed; when the driver needs external circulation, the air channel switching damper 107 switches the position to realize the conduction between the external circulation pipeline 105 and the ventilation pipeline 108, and the internal circulation pipeline 106 and the ventilation pipeline 108 are closed.
[0073] In the control method of the above-mentioned distributed automobile heating and air-conditioning system, further, the temperature adjustment device is a temperature adjustment knob, the driver rotates the temperature adjustment knob, and the position of the temperature ad...
Embodiment 3
[0083] In the distributed automobile heating and air-conditioning system described in Embodiment 1, further, the integrated panel controller 101 includes a power supply and a crystal oscillator 301, an analog quantity acquisition circuit 302, an operation panel 303, a panel acquisition circuit 304, a display unit 305, and a power drive circuit 306, power circuit 307, MCU 308 and CAN communication circuit 309;
[0084] The power supply and crystal oscillator 301 is for the integrated panel controller 101 to convert the vehicle power supply to the voltage required by the MCU308 and other control chips, and at the same time provide a clock signal for the MCU308;
[0085] MCU308 is the physical basis of strategy execution, realizing functions such as input signal acquisition and analysis, strategy calculation, control signal output and fault diagnosis;
[0086] The analog quantity acquisition circuit 302 is connected with the air duct temperature sensor 113 and the vehicle interio...
