Xia Li A How to turn on the heater and where is the switch?
In winter, everyone turns on the heater to keep warm when driving. However, for some novices, when turning on the heater, they often cannot find the heater switch because they don’t understand the car. I believe For some friends, they have encountered the problem of how to turn on the car heater. Let’s take a look below.
How to turn on the car heater
1. After the car is started, about 8-15 minutes later, the water temperature rises to normal temperature, and the heater can be turned on at this time. (That is, when the water temperature rises to the middle)
2. Adjust the circulation mode of the air conditioner to circulation in the car.
3. Adjust the warm air mode
Adjust to the warm air mode. Some cars are in red areas, and some cars are represented by the sun.
4. Turn off the AC switch
Do not turn on the air conditioner (do not turn on the AC switch), because the warm air uses the car's own heat cycle to save energy!
5. Adjust the wind speed
Adjust the air conditioner to a suitable gear and adjust the wind direction of the air outlet.
6. Adjustment mode
The direction of warm air blowing is generally forward and at the feet, and the direction of cold air blowing is generally forward.
How to turn on the heater in a car's automatic air conditioner
In fact, it can be seen that compared to manual air conditioners, automatic air conditioners have more "AUTO" buttons. So what kind of temperature is needed, we only need to control Temperature adjustment knob, then set a temperature you need, press the "AUTO" button, based on the feedback from the inside/outside temperature sensor of the car, the automatic air conditioning control unit will automatically calculate the most appropriate temperature ratio, air supply mode, Air output volume, etc., quickly reach the temperature you set.
However, the smart and economical automatic air conditioner is very disliked by many car owners who are used to manual air conditioners. For example, when the automatic air conditioner is turned on, it defaults to the maximum air volume, which makes the blowing uncomfortable and makes a loud whirring sound. , in the end you still have to adjust the air volume manually. However, the advantages of automatic air conditioning are quite obvious. It will not be too cold or too hot; the simple operation panel makes it look more advanced.
How to use car heater correctly
It is not advisable to turn on the heater as soon as you get in the car.
Because the water tank is still cooling at this time, turning on the heater will not only not heat up quickly, but will slow down the temperature rise, and also increase the burden on the engine.
The correct approach should be to start the preheating first, wait until the temperature pointer reaches the middle position, then turn on the heater, and set the air circulation to external circulation, wait 2 to 3 minutes, and wait until the cold air in the car After being discharged from the car, just set the air circulation to internal circulation.
Does it cost fuel to turn on the heater in a car?
Heat is formed by a small fan that introduces heat into the car when the engine cooling system dissipates heat to the engine. Even if the hot air vents are turned off, the heat will be dissipated outside the car, so the car heater is a waste product and will not increase fuel consumption.
The reason why air conditioning and refrigeration consumes fuel is because the air conditioning compressor needs to be driven by the engine during refrigeration. The work of the compressor consumes the energy of the engine, thus resulting in additional fuel consumption.
Precautions when turning on the heating
1. Do not sleep in the car
Same as turning on the cold air, if the fuel is not completely burned when the engine is working, it will Produces high concentrations of carbon monoxide. When the car is running, the air in the car can be replaced by convection through the air conditioning equipment, so the carbon monoxide concentration is very low.
But if the car is stopped, the heater is turned on and the windows are closed, high concentrations of carbon monoxide will enter the car, and people sleeping in the car can easily be poisoned and suffocated.
2. Don’t smoke in the car
When the heating is on, the car is a closed space, and bacteria can easily breed at this time. Smoking in the car is inherently harmful to health, as you are exposed to both first-hand and second-hand smoke.
Moreover, the amines and nicotine in the smoke will adhere to the surface of the evaporator. When the air conditioner is not used frequently or on rainy days, bacteria will spread wildly on the surface of the evaporator. When the air conditioner is turned on again, Cause air pollution in the car.
