How To Turn On The Air Conditioner In Summer To Save Fuel

- Aug 11, 2020-

1. Grasp the time to turn on the air conditioner

Many car owners turn on the air conditioner to maximum as soon as they get in the car. This is wrong! Because the engine has not yet reached a good state when the vehicle is just started, turning on the air conditioner at this time will increase the load on the engine, resulting in increased fuel consumption. In addition, the exposed interior will also emit carcinogenic gases such as benzene and formaldehyde, which affect human health.

Correct way: After the vehicle is exposed to the sun, first open the door to ventilate the air, and then turn on the blower after the vehicle is started. After natural wind blows for 5 minutes, turn on the air conditioner for external circulation, then change the internal circulation. After the air conditioner is cooled for 1 minute, turn it off Car windows.

2. Turn off the air conditioner when parking for a long time

In traffic jams or waiting for people, the engine idling for a long time will cause incomplete gasoline combustion, increase fuel consumption and produce higher concentrations of carbon monoxide. If the surrounding air is not well circulated, the carbon monoxide emitted from the engine enters the car, which will cause carbon monoxide poisoning in the car.

  Correct way: When the temperature in the car is right, turn off the air conditioner for a while and open the windows to let the air out.

3. Don't turn off the flame and then turn off the air conditioner

   Turning off the engine before turning off the air conditioner is harmful to the engine. When the vehicle is started next time, the air conditioner that is not completely turned off will start with the engine, so that high-load operation will damage the engine and cause a significant increase in fuel consumption.

Correct way: A few minutes before arriving at the destination, turn off the air conditioner first, and turn on the natural wind at the same time, so that the temperature in the air conditioning duct will rise, eliminate the temperature difference with the outside, so as to keep the air conditioning system relatively dry.

4. Alternate switching between inside and outside

When the air conditioner is just turned on, use the outer circulation to exhaust the stale air in the car, and switch to the inner circulation as soon as the temperature drops. Because the long-term maintenance of the internal circulation mode will result in a decrease in the amount of oxygen in the car, using the method of alternating internal and external circulation can also reduce the load on the engine, thereby reducing fuel consumption.

Air conditioner is not necessarily fuel efficient when it is turned on the relationship between vehicle air conditioning temperature and fuel consumption depends on whether the air conditioner is "fixed discharge" or "variable discharge". Generally speaking, manual air conditioners are fixed row, power is fixed, so fuel consumption is also fixed. The automatic air conditioner is variable row, and the compressor power changes according to the temperature.

The correct approach: If your vehicle is a manual air conditioner, it will be more fuel efficient to turn on the air conditioner at a low gear. But if it is an automatic air conditioner, the temperature must be adjusted higher, because the lower the temperature of the variable exhaust air conditioner, the higher the fuel consumption.

But if it is an automatic air conditioner, the temperature must be adjusted higher, because the lower the temperature of the variable exhaust air conditioner, the higher the fuel consumption.

6. Clean the ventilation duct and replace the filter element in time

If the air duct and air conditioning filter are blocked by dust, mosquitoes, leaves and other debris, the working efficiency of the air conditioning system will be reduced. Timely cleaning the air duct and replacing the filter element can reduce the workload of the engine, thereby reducing the fuel consumption of the vehicle.

The method of cleaning the air duct is very simple. Use a wet towel to block the air outlet of the air conditioner and adjust the air speed of the air conditioner to the maximum so that the dust will be absorbed on the towel. Owners can also use air-conditioning duct cleaners to assist high-pressure air guns for cleaning. The replacement cycle of the air-conditioning filter element is generally every 2 years, or every 12,000 to 15,000 kilometers.

7. The air outlet can be cooled quickly

After the air temperature rises, the density will decrease, so the hot air will go upwards. If the cold wind is blown upwards, the temperature inside the car will drop relatively quickly. When the temperature in the car drops quickly, the car owner can increase the temperature a bit, or turn off the air conditioning system as soon as possible, so that the fuel consumption of the car will naturally drop.

Beijing Jinnanfeng kindly reminds you: After parking, car owners must not turn on the air conditioner to sleep, nor open the windows! Because in a closed or semi-closed space, the carbon monoxide emitted by the car exhaust cannot be discharged in time, which can easily cause toxic gases to penetrate into the car and cause poisoning.
