What are the signs of a car heater?

The heat source of the warm air of the automobile air conditioner is provided by the engine coolant, which is the "water" in the water tank. Two water pipes are led from the small circulation circuit of the engine coolant and connected to the warm air water tank inside the air conditioner assembly. From this The small water tank provides a heat source for the air conditioning heater system. Even in summer, coolant at more than 90 degrees Celsius will pass through the small heater water tank.

Using air-conditioning heaters in winter will neither affect power nor increase fuel consumption. The A/C switch controls the compressor. In some models, the compressor only has a cooling function in order to save costs. Therefore, the A/C button does not need to be turned on in winter. The compressor of some models can only be used for cooling, and turning it on will have the opposite effect. The sign of the car heater is as follows:

In winter in the South, it is best to turn on the A/C to use air conditioning warm air, use compressor cooling to remove water molecules in the air, reduce air humidity, and then mix the warm air to blow out dry heat from the air outlet. of air to prevent glass aerosol in the car.
