Method of getting hot air quickly for cars in winter

First, the method of hot air on the car in winter

Because the car warm air circulates from the engine to the warm air water tank, and then the fan blows the warm air to send the heat to the water tank, the temperature of the warm air may be higher. Generally, do not turn the heater knob to the maximum position, so as to avoid the high temperature in the car and the driver dozing off. Many vehicles have a switch at the joint between the heating pipe and the engine, which should be turned on in winter.

Start the engine to warm up first, wait for the engine temperature pointer to point to the middle position, turn on the warm air and air conditioner, set the air circulation to external circulation, let the cold air in the car be discharged outside the car, wait for about 2 minutes, and then set the internal circulation air circulation.

The air conditioning button is the switch of the air conditioning compressor. If you use air conditioning in summer, you must turn on the AC button, that is, turn on the air conditioning. The warm air only uses the thermal cycle in the car, and there is no need to start the air conditioning compressor. So you only need to adjust the air conditioner and turn on the heater button, and you don't need to turn on the air conditioner switch.

In the cold season, we lift the car quickly. However, it should be noted that this warm air demisting method will not be as fast as cold air demisting at first, and it will generally last for 12 minutes. The moisture on the glass will be dried by hot air, and there will be no repeated fogging. Proper ventilation is needed. Many people often feel obvious warmth after turning on the air conditioner for a long time in the car.

First, start the engine to preheat the engine temperature pointer to the middle position, turn on the warm air conditioner, set the air circulation to external circulation, let the cold air in the car be discharged outside the car for 2~3 minutes, and then set the air circulation to internal circulation, which is easy to fog the windshield before driving in winter.

Start the engine to warm up first. When the engine temperature indicator reaches the middle position, turn on the heater and air conditioner. At the same time, the air circulation is set to external circulation, so that the cold air in the car can be discharged from the outdoor car. Then set the air circulation to internal circulation. When the engine coolant reaches a certain temperature, the coolant will flow through the heat exchanger in the heater system.

After the warm air is turned on, the temperature inside the car will not rise immediately. It will take some time, so it will be faster to use internal circulation to raise the temperature first, and then ensure the air circulation in the car when the temperature rises. The warm air temperature of driving in winter should not be too high, otherwise it will easily cause drowsiness and accidents, especially on the expressway.

Second, the winter car cleaning method

When washing the car with a hose, don't use a hose nozzle to spray water at the joint between the lock door and the trunk lid to avoid freezing at low temperature. For the lock core of the door lock, a special protective agent sprayer can be used for lubrication and corrosion protection. Wash the car after washing it. When washing the car in winter, open the door after cleaning and dry the water in time.

Let the car start again. Don't park your car for a long time after washing it in winter. The temperature at noon will not be too low. After washing the car, run for a while, shake off the residual water droplets, turn on the warm air, and blow dry the gaps between the doors and windows. Remain water and other parts to reduce the freezing of water.

Car wash shops in street shops usually only scratch off the surface water, so there is still a lot of water left in the cracks, locks and handles of the doors. It is cold in winter, especially at night, and it will naturally freeze. Driving a car and letting it run on the road can shake out the water droplets left in the door at the same time.

Although you wash your car in winter, you should have a choice when washing your car. Try to choose a warm time to wash the car, so that the car can be dried as soon as possible after washing to avoid rust on the paint. Try not to wash the car in the morning or at night, it is easy to freeze, the line of sight is not good, and it is easy to wash it.
