How often should a car's evaporator be cleaned?

[HazelRose]

The car's evaporator should be cleaned once a year. The evaporator is a radiator device for the car engine and air conditioning system, located behind the glove compartment and integrated with the heater core. There are several types of car evaporators: 1. Horizontal evaporator; 2. Vertical tube evaporator; 3. Spiral tube evaporator; 4. Air-cooling evaporator; 5. Liquid coolant evaporator. The function of the car evaporator is to transform the refrigerant from liquid to gaseous state, absorbing substantial surrounding heat. The resulting low-temperature, low-pressure refrigerant vapor then re-enters the compressor. This repeated cycle achieves cooling, providing occupants with a comfortable environment, reducing driver fatigue, and enhancing driving safety.
