There is frost on the windshield of the air conditioner in hot weather.

Frosting is normal when the front windshield is hot, which is mainly caused by the large temperature difference between the inside and outside of the windshield. The solution to this problem is simple, as long as the temperature of the air switch is increased or the air outlet of the air switch is turned to another position. Frosting on the windshield of a car is a normal phenomenon. Opening the windshield will frost not only in hot weather, but also in winter. Windows will frost in winter.

Frosting on the windshield of a car is a normal phenomenon. Opening the windshield will frost not only in hot weather, but also in winter. The frosting of windows in winter is also caused by the large temperature difference between inside and outside the windows. There are many methods of automobile defrosting, mainly air defrosting, window defrosting and glass heating defrosting.

1. air conditioning defrosting:

Turn the idle speed to AC position, and then turn on the internal circulation mode. Generally, it only takes about 1 minute to remove the frost on the window. Air defrosting is the most commonly used and effective method for automobile glass defrosting.

2. Open the window to defrost:

Open the window a little, reduce the temperature difference between the inside and outside of the car, and also remove the frost on the glass. However, this method should not be used in rainy and snowy weather.

3, glass heating defrosting:

As of July 20 19, most cars on the market are equipped with glass heating function. The principle of glass heating defrosting is to remove the frost on the window by heating the heating wire in the glass, which is a relatively efficient method.

Is it necessary to warm up the car?

For EFI engines, it is completely unnecessary to warm up the car.

Many riders have the habit of heating their cars in situ in winter. This part of riders think that the engine has just started and the oil has not yet reached the position where lubrication is needed. At this time, idling the engine in place can make the oil reach the position where lubrication is needed. Some riders think that idling in place before driving can raise the engine temperature a little, which is good for the car.

In fact, in-situ hot car is just a waste of gasoline, which is not good or even good for the car. After the engine starts for a few seconds, the oil will quickly reach the position where lubrication is needed, forming an oil film. Moreover, insufficient gasoline combustion will increase the carbon deposition in the engine when the vehicle is hot-started, and the pollutants in the exhaust gas will exceed the standard when the vehicle is hot-started.

The correct way to warm up a car is to start the engine directly in gear and start driving, but don't increase the engine speed at the beginning of driving, which can increase the load of the engine, make the engine warm up quickly, and also make the transmission system such as gearbox reach the working temperature quickly.

In the past, carburetor engine needed local preheating, and it was difficult to start carburetor engine in winter. Now the EFI engine does not need to be preheated in situ. As long as there is nothing wrong with the battery, the engine will not be difficult to start in winter.

I hope that all riders will stop warming up in place.
