Then press the A / C switch to start the air conditioner, then start the fan, press the defogger switch, the blower turned to the windshield, attached to the windshield fog will soon disappear. In addition, the air conditioning control panel has several buttons to change the direction of the air flow, you can choose to blow the upper body or foot.


Car air conditioning has two kinds of manual adjustment and automatic adjustment. The former in the air conditioning control panel has a temperature adjustment knob, adjust the knob can adjust the temperature; automatic air conditioning does not need to manually adjust, can automatically control the compartment of the circulating air and temperature, in the outside air quality changes in the air quality. This system can automatically control the temperature, wind speed and air flow. As long as the temperature is set in advance, and the wind speed and air flow mode is set to "AUTO" mode, the system will automatically select the outlet position and wind speed, and will be adjusted at any time according to the changes in the environment.

The air conditioning and cooling effect is related to the cleaning of the heat sink of the condenser. Always remove dust from the heat sink of the condenser.

Should pay attention to replace the air conditioning filter on time, if the air conditioning filter for a long time do not change, the above adsorption of dust will be more and more, and may be air-conditioned fan suction car, affecting the health of the crew.


Generally 1.3 liters above the displacement of the car, the air conditioning effect can be basically, but some 1 liter or 1 liter below the mini-car, because the engine power is small and lead to air conditioning effect is not ideal, and even open air conditioning will take a section of water The phenomenon of boiling, especially in the hot summer days.


Summer air conditioning use to pay attention to the following things: First, if the engine due to air conditioning to increase the load caused by excessive water temperature, to suspend the use of air conditioning until the water temperature is normal. Second, to avoid parking when the idle conditions in the summer high temperature for a long time using air conditioning, air conditioning can not be effectively cooled due to the system temperature and pressure is too high and loss of ring. Long-term parking air conditioning is also a threat to the safety of the occupants, because the exhaust gas from the car may be sucked into the compartment to poison. Third, when the car parked in the open air caused by the high temperature, you should first open the door so that inside the hot air escape, and open the air conditioning to disperse the heat. And then close the doors and windows to improve efficiency.
