What does FRT on a car mean?

FRT on a car should mean front. The automotive air conditioning system is a device that cools, heats, ventilates, and purifies the air inside the vehicle compartment. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. The air conditioning system has become one of the indicators of a car's functionality. 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 temperature inside the compartment; in winter, except for large commercial vehicles that use independent combustion heaters for warmth, other vehicles generally utilize the car's residual heat for heating. 2. Humidity regulation: Humidity significantly affects passenger comfort. The humidity inside the compartment should generally be maintained between 30% and 70%. Standard car air conditioning systems do not have the function to regulate humidity; only advanced luxury cars equipped with integrated heating and cooling systems can achieve this through ventilation devices. 3. Airflow regulation: The speed and direction of airflow greatly impact comfort. If the air blows directly, the speed should be limited to a certain range when the temperature is appropriate. The airflow speed can be adjusted based on passengers' living environment, age, health condition, and temperature preferences. 4. Air purification: The quality of air inside the compartment is crucial for ensuring comfort.
