Why doesn't BMW X6 have heating?

The insufficient warm air of BMW X6 may be due to the fact that the engine has just started, and the temperature of the coolant is still relatively low at this time, so the warm air will not be blown out after the warm air is turned on. Another possibility is that the heater water valve and heater water tank are out of order, which will also cause the automobile air conditioner to fail to heat.

Automobile air conditioner uses the heat of engine, and the heating principle of automobile air conditioner is very simple. When heating, the high-temperature coolant in the engine will flow through the warm air tank, and the wind from the blower will also flow through the warm air tank, so that the air outlet of the automobile air conditioner can blow out warm air.

When the car engine was just started, the temperature was relatively low. At this time, it is impossible to blow out the warm air by turning on the warm air. At this time, turning on the warm air will also slow down the temperature rise of the engine, resulting in a decrease in engine power and an increase in fuel consumption.

Extended data:

function

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.
