Should the Defroster Use Internal or External Air Circulation?

[Leilani]

Use external air circulation for the defroster. Select the appropriate air conditioning fan speed setting: During normal vehicle operation, to prevent excessive frosting of the evaporator and ensure proper functioning of the air conditioning system, the air supply speed and temperature control should not be set at the lowest setting for extended periods. When driving below 25 km/h, set the fan speed to the low-speed setting to avoid insufficient power generation and inadequate cooling. Duration of single air conditioning use: If the interior temperature has reached a comfortable level, you can turn off the air conditioning or switch it on again after a while. Prolonged use of the air conditioning can cause excessive pressure on the condenser and lead to wear and tear on the refrigeration system, so it is advisable not to use the air conditioning for too long at a time.
