What Are the Knowledge Points About Car Air Conditioning?

[LeBrody]

Car air conditioning knowledge is as follows: 1. Air conditioning vents: Based on the principle that hot air rises and cold air sinks, when using the air conditioning in the car, point the vents upward when cooling and downward when heating. 2. Frequent cleaning: Many car owners often wash their cars but neglect their maintenance. Summer often brings heavy rain and humid weather. If the air conditioning filter is not cleaned in time, it can cause odors and mildew smells in the car. 3. Occasionally use the high-speed fan setting: While using the air conditioning, occasionally setting it to the maximum fan speed can blow out residual dust in the air ducts. 4. How to use the internal and external circulation: When the car is very hot, use the external circulation to release the heat inside the car. Then, once the temperature drops sufficiently, turn on the cooling and switch to internal circulation. 5. Turn on the air conditioning weekly: Try to turn on the cooling function 3-4 times a month for about 5 minutes each time. This can effectively prevent issues like evaporator and compressor aging.
