2. The cooling system is short of cooling liquid, which leads to the warm air of automobile air conditioning. The principle is different from that of household air conditioning heating. Automobile warm air circulation is to connect a pipeline in parallel in the small circulation pipeline of engine coolant, which is connected with a warm air water tank, and the blower blows the warm air water tank to generate warm air, which is how the air conditioning warm air comes from. The lack of coolant in the cooling system is the most common and easily solved fault phenomenon that causes the warm air not to be hot.

Matters needing attention in automobile heating:
1, don't sleep in the car.
When the engine is working, if the fuel is not completely burned, it will produce high concentration of carbon monoxide. When the car is driving, the air inside the car can be convectively replaced by air conditioning equipment, so the concentration of carbon monoxide is very low. However, if the car stops, the heating is turned on and the windows are closed, high concentration of carbon monoxide will enter the car, and people will easily be poisoned and suffocated when sleeping in the car.
Don't smoke in the car.
In the case of heating, the car is a closed space, at this time it is easy to produce bacteria. Smoking in the car is inherently harmful to health, and both first-hand and second-hand smoke have been smoked. Moreover, amine and nicotine in the flue gas will adhere to the surface of the evaporator. When the air conditioner is not commonly used and it is rainy, bacteria will spread on the evaporator surface, which will cause vehicle air pollution when the air conditioner is turned on again.
Phoenix net-sleeping in the car in winter is easy to be poisoned, and improper use of warm air leads to death.
People's Network-Why is it so cold? In winter, the air conditioner and warm air are not hot as hell.
