How Long Should a Car Air Conditioning System Be Vacuumed?

[Virgil]

Air conditioning system vacuuming requires a minimum of 45 minutes. If the system is particularly dirty, it may take about an hour. Here is more information about car air conditioning: 1. The car air conditioning is a crucial comfort feature in vehicles. It contains refrigerant, typically r134a, which needs periodic replacement. If the cooling efficiency declines or the cooling speed slows down, it's time to replace the refrigerant. 2. The cooling principle of air conditioning is quite straightforward. When the AC button is pressed, the compressor clutch engages, allowing the engine to drive the compressor. The compressor then compresses the refrigerant and delivers it to the evaporator. Inside the evaporator, the refrigerant expands and absorbs heat, cooling the evaporator. The evaporator, in turn, cools the air blown by the blower, resulting in cold air from the vents. 3. The heating principle is also simple. When the heating function is activated, the engine's hot coolant flows through the heater core. The air from the blower passes over the heater core, warming the air that comes out of the vents. The car air conditioning system requires regular cleaning and disinfection to prevent bacterial growth, which can be harmful to the health of the vehicle's occupants.
