What Mode Should You Use for Car Air Conditioning in Summer?
2 Answers
In summer, use the cooling mode for your car's air conditioning. Do not enter a car that has been exposed to the sun immediately; first, lower the interior temperature. Set the air vents to blow diagonally upward, utilizing the principle that hot air rises and cold air sinks, allowing the cool air to circulate from top to bottom to cool the car. Here are methods to quickly reduce the interior temperature: Sequential Window Opening Method: First, open the same-side door or lower the window completely, while keeping the opposite-side window closed. Then, open and close the door repeatedly to allow hot air inside the car to circulate and escape. Diagonal Window Opening Method: Open all four windows or the diagonally opposite windows while driving to accelerate the circulation of hot air.
In summer, I prefer using the air recirculation mode while driving, as it enhances the AC cooling efficiency and cools down the car cabin faster. Before getting in, I always roll down the windows for a few seconds to let the hot air escape, then close them and turn on the AC with recirculation. This mode keeps the cool air circulating inside without letting in hot outside air, reducing the AC's workload and saving fuel. On long trips or when waiting parked for too long, I occasionally switch to fresh air mode to prevent stuffiness and ensure comfortable breathing. Additionally, regular checks of the AC filter are crucial—excessive dust can weaken cooling and even foster mold, so I clean it every six months to enjoy worry-free cool breezes.
