2. The workload of the air conditioner fan is too large, which may ablate the air conditioner motor;
3. The blower regulating electric appliance is out of order, which leads to the reduction of air supply. If the filter element of the air conditioner is too dirty, it should be replaced. When turning on the car air conditioner, first try whether there is hot air, listen to whether the fan is operating abnormally, and check whether the air duct is unobstructed.
Extended data:
Heat pipe heating system: the heat pipe heat exchanger is vertically installed in the floor of the carriage, with condensation and heat release section above the floor and exhaust gas heating section below the floor.
The exhaust gas discharged from the exhaust pipe of the automobile engine is introduced into the heat pipe heat exchanger, and the heat pipe heat exchanger is filled with liquid ammonia. After being heated, liquid ammonia vaporizes, rises to the upper part of the heat pipe heat exchanger, exchanges heat with air, and heats the air entering from the vent.
After the air is heated, it is blown into the carriage by the blower for heating, and the released ammonia condenses and flows back to the lower part, and then the next working cycle is completed.
Heat exchanger heating system: When heating, turn the waste gas valve 4 to the position shown in Figure 2, the hot air in the exhaust pipe is introduced into the heat exchanger 5, and the cold air blown by the blower is introduced into the car for heating or defrosting after absorbing heat through the heat exchanger.
