What is the working principle of automobile heating system

Automobile warm air working principle:

1. Currently, the warm air on the car is mainly in the form of water heating type, its heat source from the engine coolant, when the coolant temperature is high, it flows through the heat exchanger in the warm air system, and the blower will be the air and the engine coolant heat exchange, and finally the heated air through the various air vents into the car. Simply put, the heat of the engine coolant is not used for nothing, and the car warm air is through the engine coolant heat transfer heating, so it will not add extra fuel consumption!

How to open the warm air without air conditioning:

1) After the car starts, do not rush to open the air conditioning, wait until the engine water temperature gauge reaches the middle position, and then open the warm air.

② A/C is the abbreviation of air condition, it is the air conditioning cooling switch, do not need to open the A/C when you open the warm air.

③ Warm air temperature control at 18 ℃ ~ 25 ℃ can be. For one thing, this is the most comfortable temperature for the human body, and for another, if the temperature is any higher the engine may need to do extra to increase fuel consumption.

④ Adjust the circulation of the air conditioner to the internal circulation, if you feel that the air inside the car is a little turbid, oxygen content decline, you can adjust to the external circulation.

⑤ Using the air conditioner for a long time will increase the burden on the condenser and cause wear and tear on the cooling system. Therefore, you can turn off the air conditioner at the right time, let it "rest a little", and then turn it on again every now and then.

6 Parking off the engine before three or five minutes should close the air conditioning, which can not only reduce fuel consumption, but also to avoid air conditioning odor. If you do not close the air conditioning on the mold in the air conditioning reproduction, and then start again, the vehicle will start with the air conditioning pressure ignition, so that the high load will cause damage to the engine.
