How to turn on the heater of Changhe Freda van?

The way to turn on the air conditioner of Changhe Freda van is to press the A\/C switch on the center console after starting the vehicle, and then twist the temperature switch to realize cooling and heating. The function of automobile air conditioning is to control the temperature, humidity, air cleanliness and air flow in the car compartment in the best state, to provide a comfortable riding environment for passengers, to reduce travel fatigue and to create good working conditions for drivers, which plays an important role in ensuring safe driving.

The reason why the automobile air conditioner does not cool;

1, condenser and water tank; The heat dissipation of condenser and water tank will also affect the use of air conditioning. If not cleaned for a long time, the condenser and water tank will be covered with foreign dust.

2, the quality of the expansion valve; The expansion valve is an important part in the refrigeration system, which is generally installed between the liquid storage tank and the evaporator. Inferior expansion valve will make refrigerant not play its due role;

3. Use of fluorine; Many car owners think that the more fluorine in air conditioners, the better, but this is not the case. In the process of adding fluorine, the amount of fluorine is neither too much nor too little. Less will make the pressure in the air conditioning pipe insufficient, and more will make the pressure too high. In the above two cases, the air conditioner cannot operate normally for refrigeration;

4. Quality and purity of fluorine; The quality and purity of fluorine play an important role in automobile air conditioning. Usually, inferior fluorine will lead to low efficiency of air conditioning operation.
