The basic principle of automobile air conditioning heating is very simple. After the warm air is turned on, the liquid cooled after high temperature in the engine will flow through the warm air box, and the wind from the blower will also pass through the warm air box to blow warm air from the air outlet of the air conditioner, thus rapidly raising the temperature inside the car. When the engine temperature pointer reaches the middle position, turn on the heating air conditioner.
In addition, the air circulation is set as external circulation to discharge the cold air inside the car outside. After waiting for 2~3 minutes, set the air circulation to internal circulation.
In cold winter (even in late autumn and early spring), the automobile heating system can provide heating for the automobile and increase the temperature inside the automobile. In winter, spring and autumn, when the air humidity is high and the temperature difference between the inside and outside of the car is large, frost and fog will form on the window glass, which will affect the driver's sight and is not conducive to driving safety. At this time, turning on the heating system can remove the frost and fog on the window glass.
Does it cost gas to turn on the heater?
It won't cost oil to turn on the heating. When the heater is turned on, the coolant will flow into the heating box, which can help the coolant dissipate heat and protect the vehicle.
The heat mainly comes from the water tank of the car, and some heat is introduced into the car through the blower. This heat itself is the inevitable product when the car is running, and it does not need special heating by the compressor, so it will naturally not increase the fuel consumption of the car.
