There are two main reasons why the car warm air is not hot enough after it is turned on. There is something wrong with the cooling system of the engine or the control mechanism of the warm air, which can't work normally. You can check the temperature of the two intake pipes of the small warm air tank. If both are hot enough, there is nothing wrong with the heating control mechanism.
Warm air is an effective and basic heating facility in the car, using PTC and water heating device. PTC heater is an electric heating device, just like an electric heater. Only some high-end cars will combine water heating with PTC, while pure electric vehicles can only use PTC heater. Water heating type is formed by engine heat dissipation.
Extended data:
The use of automobile warm air is introduced as follows:
When the car just started, the internal lubrication of the engine was not enough and the temperature of the water tank was relatively low. At this time, turning on the warm air is not only not conducive to the increase of the temperature in the car, but also increases the load of the engine, and the fuel consumption is certain.
The normal practice should be to start it for about 5 minutes, and then turn on the warm air after the water temperature rises. The A/C key is to start the compressor, which is to turn on the air conditioner in layman's terms. Car warm air is the heat generated by the car using its own thermal cycle, and it doesn't need a compressor to work, so it costs oil to press it.
Phoenix. Is the com- air conditioner heater broken in winter? It turns out that they are the culprit.
Phoenix net-it doesn't cost oil to open warm air like this in winter!
