Why Use Recirculation Mode in Summer?
2 Answers
Using recirculation mode in summer improves cooling efficiency. Below is an introduction to recirculation mode: 1. Overview: Recirculation is a state of the vehicle's air conditioning system. In this mode, the air exchange channels between the interior and exterior of the vehicle are closed. When the fan is off, the air inside the car does not circulate. When the fan is on, the airflow drawn in comes solely from inside the vehicle, creating an internal air circulation. 2. Advantages: Recirculation primarily and effectively prevents external dust and harmful gases from entering the car, such as when driving through smoke, dust, areas with strong odors, or in heavy traffic, blocking harmful exhaust emissions from preceding vehicles. Recirculation enhances the cooling and heating efficiency of the air conditioning system and provides better insulation. 3. Disadvantages: Prolonged use of recirculation can degrade the air quality inside the car, potentially causing dizziness or discomfort. It's advisable to switch to fresh air mode (outside air) for a few minutes after using recirculation for a while to allow fresh air to enter and improve air quality.
I find that using the recirculation mode with the air conditioning in summer is particularly effective, mainly because it cools the car down faster. When hot outside air is drawn in, the AC system has to expend more energy to cool it down, whereas recirculation only processes the air inside the car, reducing the workload on the compressor and delivering colder, more efficient airflow. For example, when I drive in the city on hot days or in traffic jams, turning on recirculation instantly makes the cabin much more comfortable, while also preventing external pollutants like car exhaust or pollen from entering, which is beneficial for health. Once you get into the habit, this mode can also help save fuel, as the AC doesn’t have to work as hard, reducing the car’s overall energy consumption—ideal for long trips. In short, recirculation is my go-to setting in summer, as a simple adjustment significantly enhances driving comfort.
