The car does not cost oil to drive the warm air. Because the main source of heat from the car is the heat emitted by the normal operation of the engine, this is the heat generated by the normal operation of the engine, but it has been treated by the air conditioning and heating system, and finally transported to the inner car to increase the temperature in the car. The normal operation of the engine can provide warm air, without additional burden on the engine, it will not increase the fuel consumption of the start, that is to say, it does not cost oil to open the warm air.
In the summer when the temperature is high, the temperature in the car will rise rapidly, at this time, turn on the car air conditioner, open the refrigeration mode, you can quickly reduce the temperature in the car to cool down the car. However, turn on the car air conditioning refrigeration mode, the vehicle fuel consumption will have a significant increase, this old driver knows that the air conditioning refrigeration compressor is directly driven by the engine, increasing the load of the engine, fuel consumption is also normal. So, if when the temperature is relatively low, we turn on the heating mode of the air conditioner, will the fuel consumption of the vehicle increase, and will the car air conditioner have an impact on the fuel consumption of the vehicle? And the little car dad, let's take a look.
Let's start with the working principle of car air conditioning heating and opening the warm air mode, the heating working principle of car air conditioning, we are popular and simple. The normal operation of the engine will generate heat, and this heat also needs to be dissipated through the heat dissipation system in time. Then, we collect the heat emitted by this part and convert it into a warm air to transport it to the car, which realizes the heating of the air conditioner.
The actual working principle, the main heating component radiator core, similar to our common radiator, carries the coolant generated by the heat generated by the normal operation of the engine, and then passes through the special radiator core to heat the air around the radiator core. Then, the air conditioning blower, similar to the fan, the heated air is transported to the car through the warm air pipeline, and the hot air is blown into the car, so as to increase the temperature in the car, which achieves the purpose of air conditioning heating. Because the heat comes from the heat generated by the engine, the air comes from the engine compartment, which is why sometimes the warm air will have a peculiar smell.
According to the working principle of the air conditioning heating mode, we can clearly know that in the process of warm air generation, only the heat generated by the normal operation of the engine is used, and there is no additional increase in the load of the engine. The engine only needs to keep running normally, generate heat, and then supply it to the car to raise the temperature inside the car. In the air conditioning heating mode, the fuel consumption of the vehicle will not increase significantly, or it will not increase the fuel consumption of the vehicle because the air conditioning heating is turned on, that is, the car air conditioning heating is turned on.
After knowing the working principle of air conditioning heating, let's see if it costs oil to turn on the air conditioner heating? The answer should be clear! However, careful old drivers may find that when the temperature is relatively low, when the air conditioner is turned on, the vehicle fuel consumption will still have some changes, and it will be slightly higher, why is this?
In fact, when the temperature is relatively low, the vehicle fuel consumption is high, or slightly increased, and the warm air that turns on the car air conditioner is not much related. Mainly due to the low temperature, the normal operation of the engine needs to reach a certain temperature range, in the process of reaching this temperature range, that is, the engine needs to heat up quickly, it will increase the supply of fuel, so that the engine can heat up rapidly to achieve the appropriate working temperature range. This process of increasing fuel supply will lead to a slight increase in vehicle fuel consumption.
Similarly, if the temperature is particularly low, we directly open the air conditioning heating mode to adjust to a higher temperature, or automatic air conditioning, automatically adjust the temperature to achieve a rapid increase in the temperature in the car. In this case, the temperature is low, the engine heats up to a certain amount of time, at this time the air conditioning system gives the instructions that need to heat up quickly, what to do? Only the engine can be quickly heated up first, also by increasing the engine speed, increasing the engine fuel supply, rapidly heating the engine, accelerating the heat generation, and then transported to the car to achieve the temperature set by the air conditioner. In the case of often using this forced adjustment to heat up, the fuel consumption of the vehicle will also increase somewhat.
When the temperature is relatively low, from the perspective of saving vehicle fuel consumption, we need to wait for the vehicle engine to heat up first, after reaching the normal working temperature, and then turn on the air conditioning heating mode. At this time, the engine has been heated up, delivered to the car is warm air, before the engine does not heat up, even if the heating mode is turned on, the conveyor will still be cold air. However, the configuration of high-end models will take into account the low temperature of the engine, and the vehicle will be equipped with electric heating auxiliary air conditioning heating, without our manual adjustment, so that the air conditioning can be automatically adjusted.
