Which is the Recirculation Mode in Car Air Conditioning?

The symbol for air recirculation is: a car icon + an arrow turning inside the vehicle. Below is an introduction to the car's recirculation and fresh air modes: 1. Usage: Use recirculation mode in traffic jams and fresh air mode on highways. The use of recirculation and fresh air modes should be combined with the air conditioning and heating system. By using the fresh air mode, you can breathe fresh air from outside the car. When driving on highways for a long time, the air inside the car can become stuffy and uncomfortable, and you can't open the windows. In this case, you should use the fresh air mode to let in some fresh air. If the warm air in winter feels too hot, you can turn off the fan and switch to fresh air mode, maintaining the temperature inside the car while getting fresh air, which will feel more comfortable. 2. Principle: The recirculation mode closes the airflow channel between the inside and outside of the car. Without the fan, there is no airflow circulation. When the fan is turned on, the airflow drawn in comes only from inside the car, creating an internal airflow cycle within the vehicle.
In car air conditioning systems, the recirculation button is usually represented by a small car icon with two arrows circulating inside the vehicle. Some models label it as "RECIRC". When pressed, the AC recirculates the air inside the cabin instead of drawing fresh air from outside. Having driven for over a decade, I remember being initially confused by the button layouts, but recirculation proves particularly useful during summer or traffic jams. A single press rapidly cools or heats the cabin while blocking external dust and pollen. When outdoor temperatures soar in summer, activating recirculation cools the interior within 1-2 minutes while improving fuel efficiency. For long-term use, remember to occasionally switch to fresh air mode to prevent moisture buildup and fogging. Button locations vary across models - commonly found on steering wheel-mounted climate panels or infotainment touchscreen menus.
As a car enthusiast, I find the recirculation function super interesting: it acts like a little air butler. Pressing the button with the car arrow icon closes the outside air vent, allowing only the cabin air to circulate through the AC. This design aims to save energy and protect health, such as avoiding inhaling foul air during smoggy days or heavy traffic with lots of exhaust. In my car, the button is located at the top left corner of the AC panel, labeled "RECIRC" – a simple press delivers immediate results. When the car is crowded, activating recirculation can reduce AC workload and cool faster. But don't keep it on all the time, as CO2 buildup may cause dizziness; it's best to toggle flexibly based on air conditions. Button positions vary by brand – you can check the manual or APP diagrams for reference.
Using the car's air recirculation mode is quite common when driving. I rely on it daily for peace of mind: the button usually has an arrow symbol inside the car, and pressing it makes the AC circulate air only within the cabin. I use it during morning traffic jams to keep exhaust fumes and strange odors out, keeping the interior fresh; it also helps warm up the car faster in winter. Sometimes the button is near the AC controls, easy to find once you're used to the automatic switching—no need to memorize its location. Recirculation allows for more precise temperature control, reduces AC noise, and makes waiting in the car much more comfortable.
