How to turn on the air conditioner of a Petrol Car to save fuel in summer?

1. When to turn on the air conditioner has a great effect on cooling effect and energy saving. It is no exaggeration to say that the internal temperature of a Petrol Car that has been exposed to the sun can be as high as forty or fifty degrees. At this time, the first thing to do is to open all the windows, adjust the air output of the air conditioner to a high setting (be careful not to turn on the A/C), and Change the circulation mode to external circulation to drive out the high temperature inside the car through the air outside the car. Then we drive on the road, turn on the A/C switch and change the mode to internal circulation. At this time, due to the prior cooling of the outside air, the cooling pressure of the air conditioner will be very small, and the temperature inside the car will soon drop. At the same time, It also plays an energy-saving role.

2. When to turn off the air conditioner, time is equally important, which can protect the air conditioning system of Roewe Car and reduce fuel consumption. When the windows are closed, although the interior of the car cannot be completely sealed, the temperature inside the car will not rise immediately after the air conditioner is turned off. In addition, the air from the air conditioner outlet will still be very cool. To put it simply, when we are about to reach our destination when driving, we can turn off the compressor in advance and keep the air conditioner outlet blowing out. This can not only ensure the coolness in the car, but also dry up the water-ice mixture on the air conditioner evaporator. , preventing mold from producing odor, not only reduces fuel consumption, but also effectively prevents the evaporator from becoming moldy. When the vehicle is ignited and started next time, the compressor needs to be started even if the air conditioner is not turned off, which will cause a huge impact on the battery.
3. Frequent stop-and-go driving in urban areas at low speeds and frequent starting of the vehicle consumes more fuel. If the air conditioner is started when starting the vehicle, it will consume more fuel. In response to this situation, experienced drivers suggest turning off the air conditioner or opening the windows to cool down. In other words, when we are forced to stop and wait while driving in urban areas, we should turn off the air conditioner before turning off the engine and then turn off the engine.
4. The wind direction of Petrol Car air conditioners is the same as that of our home air conditioners. If the air outlet is upward, the cooling effect will be better. It can be understood that if the wind direction of the air conditioner is directed downward, the interior space of the car can be divided into two layers. The mixed gas (air conditioning) in the lower layer is denser and will be emitted all the way downward, while the gas in the upper layer is difficult to To cool things down, turn the air conditioning outlet upwards, and the air conditioner will flow from top to bottom. Soon the temperature inside the car will drop, and the cooling effect will be better.
5. From the analysis of the above theory, it can be seen that the lower the air conditioning temperature of a Petrol Car, the fuel consumption is likely to increase. Therefore, the temperature should be appropriately cooled according to the number of people in the vehicle. For example, if one or two people are riding in the vehicle, Just adjust the temperature to level 2. There is no need to adjust the temperature lower.
6. Blowing the air conditioner for a long time sometimes makes us depressed and increases the fuel consumption of Aki Roewe Car. Therefore, some car owners choose to close the air conditioner and drive the windows to cool down. The method is advisable. Natural wind is indeed cleaner than treated air-conditioned air, but driving the windows does not necessarily save fuel. It is recommended to use 80km/h as the dividing line. Below this speed, you can choose to open the windows to cool down. , above this speed, it is recommended to turn on the air conditioner to cool down, because when driving at high speed with the windows wide open, a Petrol Car needs to overcome additional air resistance, and its fuel consumption is much higher than turning on the air conditioner.
