Should the Air Conditioning Evaporator Box Be Cleaned?

The air conditioning evaporator box needs to be cleaned regularly; otherwise, it can breed a lot of bacteria and accumulate dirt. Here are the details: 1. Cooling Principle: The car air conditioning is a very important comfort feature in vehicles. The cooling principle is quite simple. When the AC button is pressed, the compressor clutch engages, and the engine drives the compressor to operate. The compressor continuously compresses the refrigerant and delivers it to the evaporator box. Inside the evaporator box, the refrigerant expands and absorbs heat, cooling the evaporator box. The evaporator box then cools the air blown by the blower, allowing the air conditioning vents to blow cold air. 2. Heating Principle: The heating principle of car air conditioning is also straightforward. When the heating function is turned on, the high-temperature coolant from the engine flows through the heater core, and the air blown by the blower passes through the heater core as well. This allows the air conditioning vents to blow warm air.
