1. External circulation mode: to ensure air circulation in the car
People who stay in an air-conditioned environment for a long time will experience nasal congestion, dizziness, runny nose, fatigue and other symptoms due to poor air circulation. This is also what people often call "air conditioning disease." Similarly, drivers who drive long distances or stay in the car for a long time with air conditioning can also suffer from this "air conditioning disease."
Since the compartment is a relatively small and closed space, accessories, foot pads, leather seat covers and other items in the compartment will volatilize harmful gas molecules or bacteria under high temperature. In this case, if the air is not circulating, it will be very harmful to the human body. Great harm. Therefore, it is best to adjust the air conditioner to the outer circulation gear to ensure the air circulation in the car and keep a certain amount of fresh air in the car. At the same time, the temperature difference between indoor and outdoor should not exceed 7°C.
2. Regular disinfection: avoid air conditioning as a source of pollution
The evaporator and ventilation pipes of car air conditioners are kept in the dark for a long time, and the internal environment is high and humid, so that dust, germs and other impurities in the air in the car will be adsorbed on the pipe wall and condense into dirt. These dirt will not only affect the cooling of the air conditioner The effect will also make the air conditioner become a source of pollution in the cabin.
Automobile air conditioners are generally disinfected once in about 6 months, and the service life of air conditioner filters is generally 1 year, and they need to be cleaned and replaced after the validity period. It is best for car owners to go to the auto repair shop to clean and maintain the car regularly to avoid the air conditioner of the car becoming a source of air pollution in the car compartment.
3. Circulation mode: best cooling effect and most fuel efficient
While car air conditioning brings a comfortable environment to the cabin, it also increases the car's fuel consumption. Many car owners turn on the car air conditioner to the maximum gear as soon as they enter the car, which is the most fuel-consuming. The correct method is to first open the windows of the whole car, let the circulating air take away the hot air in the car, and turn off the windows when the temperature in the car is the same as the outside, then turn on the air conditioner, and adjust the air conditioner to the circulating gear, so that the cooling effect The best and most fuel efficient.
Finally, Beijing Nanfeng friendly reminds all car owners that before arriving at the destination, you can turn off the air conditioner in advance. This will not only save fuel, but also the temperature rise in the air conditioner pipe can avoid water accumulation in the pipe and make the bacteria in the pipe have no room for survival. Maintain the air environment inside the car.
