How to Turn on the Car Air Conditioner in Winter?

When turning on the car air conditioner in winter, adjust it to the external circulation mode. Below is a relevant introduction to car air conditioning: 1. Air Conditioning Layout: Different types of air conditioning systems have varying layout methods. Currently, most cars widely adopt the integrated heating and cooling air conditioning system. Its layout involves assembling components such as the evaporator, heater core, centrifugal blower, and control mechanism into one unit, referred to as the air conditioning assembly. 2. Air Conditioning Components: Modern air conditioning systems consist of a refrigeration system, heating system, ventilation and air purification devices, and a control system. Generally, a car air conditioner mainly includes components such as the compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, piping, condenser fan, vacuum solenoid valve, idle speed controller, and control system. The car air conditioning system is divided into high-pressure and low-pressure lines. The high-pressure side includes the compressor output side, high-pressure lines, condenser, receiver-drier, and liquid lines; the low-pressure side includes the evaporator, accumulator, suction line, compressor input side, and compressor oil sump.

As a seasoned driver with over a decade of experience, I have my own routine for using the air conditioning in winter. Upon entering the car, I don’t rush to turn on the AC right away because the engine is still cold from startup. I usually wait a few minutes for it to warm up before pressing the AUTO button, which lets the system adjust automatically. Then, I rotate the temperature knob to set it around 22 degrees—comfortable yet fuel-efficient. I don’t worry about the fan speed as it regulates itself. Fogging up is a major issue in winter, so I always check if the windshield defogger is on; otherwise, the fog can blur visibility, which is quite dangerous. I also pay attention to cabin air quality by switching to external circulation for a while to avoid CO2 buildup. During regular maintenance, I make sure the AC filter is clean to prevent dust from blowing out. In short, warming up the car gradually before using the AC ensures both safety and peace of mind.

I love the tech features in my new car, so using the AC in winter is super easy. As soon as I start the car, I just press the AUTO button, and it intelligently adjusts everything. For temperature, I turn the knob to set it between 20 to 24 degrees—warm but not stuffy. The fan speed changes automatically; I never have to adjust it manually—the smart system knows when to increase or decrease the airflow. The central control screen also allows for more detailed settings, like switching to recirculation mode for quick heating or to fresh air mode to prevent the cabin air from getting stale. In winter, when the windows fog up easily, I find that turning on the defogger clears them up in seconds. What about fuel consumption? When I drive on the highway, I set the AC to a moderate level, so it doesn’t consume too much fuel. Technology really makes things convenient and saves me a lot of time.

Safety driving always comes first. In winter, using the air conditioning mainly serves to prevent fogging and enhance alertness. After getting in the car, I start the engine and wait two to three minutes for it to warm up, then press AUTO to activate the air conditioning. Set the temperature higher, say 25 degrees, and adjust the airflow direction to defrost the front windshield. Once the fog clears, visibility improves significantly, greatly reducing accident risks. Check if the fuses are functioning properly, as older cars are prone to malfunctions; replace the filter if it's dirty to ensure healthy breathing. After prolonged use of the air conditioning, I briefly switch to external circulation to prevent dizziness. Before each trip, test the air conditioning functions to ensure everything runs smoothly. A few simple steps can save lives and bring peace of mind.

Every day when I drive my child to school, the car needs to be warm in winter. After starting the engine, I wait for it to warm up a bit, then press the AUTO button to turn on the air conditioning. I rotate the temperature knob to around 23 degrees—not too hot or cold, just perfect. The fan speed is automatically controlled, so I rarely adjust it manually. If my child says it feels stuffy, I switch to the external air circulation to let in some fresh air. The front windshield defogging function is a must; otherwise, fogging up makes it hard to see the road, which is quite dangerous. Since there are elderly people at home, I regularly maintain the air filter to keep the air cleaner. Fuel consumption? I try not to set the temperature too high, keeping it within a comfortable range to save a bit on fuel costs. The overall operation is simple, ensuring a comfortable ride for the whole family.
