What Causes the Front Windshield to Become Blurry?
1 Answers
Front windshield blurriness occurs due to a temperature difference between the inside and outside of the vehicle, leading to fogging, which makes it appear blurry. This situation can be resolved by turning on the air conditioning and directing cold air at the windshield, which will clear the fog in 3-5 seconds. Below are the functions of a car's air conditioning system: 1. Temperature Regulation: This is the primary function of car air conditioning. In summer, the cooling system produces cold air to lower the cabin temperature; in winter, except for large commercial vehicles that use independent combustion heaters, most vehicles utilize residual heat for warming. 2. Humidity Regulation: Humidity significantly affects passenger comfort. Cabin humidity should generally be maintained between 30% and 70%. Standard car air conditioning systems do not regulate humidity; only ventilation systems or advanced luxury vehicles with integrated heating and cooling systems can adjust humidity. 3. Airflow Regulation: The speed and direction of airflow greatly impact comfort. If air is blown directly, the speed should be limited within a certain range when the temperature is appropriate. The airflow speed can be adjusted based on passengers' living environments, age, health conditions, and temperature preferences. 4. Air Purification: Cabin air quality is crucial for ensuring comfort.
