How to turn on the hot air of the car? How to use car heating correctly

When driving on the road, will your hands be so cold that you can't tell the brake from the accelerator? Many drivers want to turn on the heating, fearing that fuel consumption is not cost-effective. In fact, automobile heating and refrigeration air conditioning are different. Next, I will tell you some common sense and precautions about car heating. How to turn on the car heater: After the car is started, the water temperature rises to normal temperature after about 8- 15 minutes, and the heater can be turned on at this time (that is, when the water temperature rises to the middle). Adjust the cycle mode of air conditioner to in-vehicle cycle; Adjust the heating mode to warm air mode, some cars are in the red area and some cars are instructed by the sun; Turn off the AC switch and don't turn it on, because the warm air uses the heat cycle of the car itself to save energy! Adjust the wind speed and mode. Warm air blows forward and cold air blows forward under your feet. Does the car heater consume much oil? There must be many people wondering: why do air conditioners and refrigeration consume a lot of oil, but heating air does not consume much oil? In fact, if the heater consumes fuel, you must have turned it on in the wrong way. The reason why the air conditioner consumes oil is because the compressor of the air conditioner needs to be driven by the engine during refrigeration, and the work of the compressor needs to consume the energy of the engine, thus generating additional oil consumption. The principle of heating is different. The car heater does not need a separate device to work. It uses the coolant heated by the engine to change the circulation route and enter the car to generate hot air. In fact, it can be regarded as waste utilization, because even if it does not turn into warm air, it will be discharged outside the car. How to use the car heater correctly: It is not advisable to turn on the heater as soon as you get on the bus. Because the water tank is still in the cooling state at this time, turning on the heating will not only slow down the heating speed, but also increase the burden on the engine. The correct way is to start preheating first and then turn on the warm air after the temperature pointer reaches the middle position. At the same time, set the air circulation to external circulation, wait for 2 to 3 minutes, and then set the air circulation to internal circulation after the cold air in the car is discharged from the car. Basic knowledge of automobile heating: you don't need to turn on the AC button to turn on the heating. If you use heating, you don't need to turn on the AC switch. The AC key is the key to turn on the air conditioning and refrigeration of the car. Press this key, the compressor will start to work and blow out cold air. Many car owners will turn on the air conditioning button when the temperature is the highest, which is completely opposite, wasting oil, hurting the car and slowing down the temperature rise inside the car. How to quickly increase the temperature inside the car: when getting on the bus, it is not appropriate to turn on the heating. Gu, the technical director of the after-sales service department of the store with many years of experience in automobile maintenance, said that when the engine was just started in winter, the temperature of the water tank was still in a low temperature state, and the wind blown out by turning on the air conditioner immediately was also cool. This method will not only make the temperature in the car rise rapidly, but also increase the burden on the engine and delay the normal temperature rise of the engine. The correct way is to start the engine warm-up, wait for the engine temperature pointer to rise to the middle position, and then turn on the heating air conditioner. At this time, it should be noted that the air circulation is set to external circulation first, so that the cold air in the car can be discharged outside the car. Wait a few minutes, and then set it as an internal loop. This operation is more conducive to rapid temperature rise. Precautions for heating: don't sleep in the car. Like the principle of turning on cold air, if the fuel is not completely burned, the engine will produce high concentration of carbon monoxide. When the car is running, the air inside the car can be changed by convection through air conditioning equipment, so the concentration of carbon monoxide is very low. But if the car stops, turn on the heating and close the window, high concentration of carbon monoxide will enter the car.
