Changfeng cheetah warm wind is not hot. What does it have to do with the air conditioning filter?
1, heater water tank blocked
There are many tiny cooling pipes inside the heater box, which are as easy to block as the radiator of the water tank. After the warm air tank is blocked, the cooling liquid flowing through it is slow and the heat is insufficient, which leads to the phenomenon that the warm air of the air conditioner is not hot and needs to be cleaned in time.
2. The cooling system lacks coolant.
Automobile warm air is a parallel pipeline in the small circulation pipeline of engine coolant. It is connected with the warm air tank, and only when the blower blows the warm air tank will warm air be generated. If there is no coolant, it will also lead to the phenomenon that the warm air is not hot, which is also a common warm air fault in the process of daily car use.
3, thermostat failure
The main reason why the thermostat is not hot is that the thermostat cannot be closed. After the thermostat is always open, the coolant will circulate from the idle speed of the engine. When the ambient temperature is low, even if the water temperature is not hot, warm air will not be hot.
Extended data
Matters needing attention in the use of automobile warm air:
1. Turn on the heater after ignition.
In winter, the temperature is relatively low. Many car owners turn on the warm air after getting on the bus. It is not only uncomfortable to get on the bus and turn on the warm air, but also increases the burden on the engine. Warm air should be used after the water temperature pointer reaches the middle position or the blue indicator goes out, so that you can have more comfortable seating space.
2. Turn on the warm air when idling for a long time.
It is really uncomfortable not to turn on the warm air in winter, but it is easy for carbon monoxide poisoning to turn on the warm air at idle for a long time, especially when sleeping in the car, which is more dangerous. It is suggested to leave a gap when turning on the warm air at idle speed for a long time to ensure the air circulation in the car.
3. There is fog in the car and you dare not turn on the warm air.
In winter, when the temperature is low and the temperature difference between inside and outside the car is large, fog will appear. Many car owners will turn off the warm air and open the window. When the fog dissipates, they can use warm air to remove the fog and blow the wind to the windshield. Warm wind will soon blow away the moisture on the glass, and there will be no fog after the glass temperature rises.
