Najing IVECO A40.10 middle-roof light car(produced in Henan)air conditioner circuit(figure 24). The power supply of air conditioner switch 10 comes from car center junction box G9 terminal(15/A line), only the ingition switch turns on, the air conditioner hand-operated switch may refrigerate with different speeds (or ventilate). Manual control Ⅰ gear: turns on, LED V14 lights on, it means air conditioner is conduction, relay 17 pulls in, evaporator fan 1, 3 and low speed ventilation. Manual control Ⅱ gear: turns on, relay 18 pulls in, middle speed ventilation. Manual control Ⅲ gear: turns on, realy 19, 20 pull in, high speed refrigeration(or ventilation). The above 3 gears, temperature control switch 11 also works, under the action of thermal resistor 21, it controls relays 14, 15, 16 with the change of indoor temperature, then to turn on/off compressor 13, condenser fans 6, 7, 8, 9. Temperature control switch 11 is also under the action of pressure control switch 5, when the high voltage is too higher(pipeline is stoppage, too much refrigerating fluid), low voltage is too lower(too little refrigerating fluid or it is spilling), switches M, L, H make temperature control switch cut off, the compressor stops to work, and the high voltage malfunction indicator light HP or low voltage malfunction indicator light LP turns on, it reminds driver of repairing.
