Stay Cool on the Road: Mastering Car Ventilation

“It’s scorching hot! How can anyone drive without some cool air?” We’ve all likely uttered this sentiment while traveling by car on a sweltering summer day. That’s when utilizing natural ventilation becomes your saving grace.

What is Natural Car Ventilation?

Natural car ventilation refers to using the flow of fresh air from outside to cool the car’s interior, instead of relying on the air conditioning system. This seemingly simple method offers surprising benefits, helping you save fuel and enjoy the fresh air.

Advantages of Natural Car Ventilation

• Fuel Efficiency: Not using the AC reduces the load on the engine, leading to better fuel economy, especially during highway driving. According to Nguyen Van A, a technician at Ha Thanh Auto Repair (Viet Tri), using natural ventilation can save you 5-10% on fuel compared to using the AC.
• Fresh Air Enjoyment: Natural ventilation allows you to enjoy the fresh, natural air, especially when driving through peaceful countryside or scenic coastal roads.
• Reduced Risk of Dry Skin and Sore Throat: Unlike air conditioning, natural ventilation doesn’t dry out your skin or nasal passages, protecting your health and that of your family, especially children and the elderly.

Disadvantages of Natural Car Ventilation

• Ineffective in Extreme Heat: On extremely hot days, when the outside temperature is significantly higher than inside the car, natural ventilation can be counterproductive, making the car feel even more stuffy.
• Dust and Pollution: When driving on busy, polluted roads like Kha Van Can Street (Thu Duc), natural ventilation can allow dust and pollutants to enter the car, affecting your health.
• Noise: Natural ventilation can increase the amount of noise from the outside environment that enters the car, potentially causing discomfort for passengers.
