Adjust the circulation mode of air conditioner to in-vehicle circulation, and use temperature adjustment to raise the temperature. Job has a quite humanized configuration, that is, the rear air outlet, but the rear air outlet is only a cooling air outlet with no heating function. This is just a simple internal loop.
There must be no warm air when job starts the engine in winter (at this time, the temperature of the water tank is not enough to heat the air and blow out warm air). If the warm air is turned on at this time, the engine will accelerate the preheating, that is, change the ignition advance angle and generate more heat to heat the antifreeze in the water tank. Fuel consumption will increase a lot at this time.
Extended data:
The functions of Geely Job's automobile heating system are introduced as follows:
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. The air humidity is high in winter, spring and autumn. When 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.
Automobile heating system is a complete set of devices that blow cold air to the surface of heat exchanger, absorb its heat and introduce it into the car, thus increasing the temperature inside the car.
