Why does the noise persist after replacing the new belt when the air conditioning is turned on?
1 Answers
Replacing the new belt but still hearing noise when the air conditioning is on is due to insufficient belt tension or excessively high refrigerant high-pressure, or issues with the compressor's clutch. Choosing the appropriate air conditioning temperature: In summer, many people prefer to set the temperature very low. However, setting the temperature too low can affect health, so it's essential to adjust the air conditioning temperature appropriately. The most comfortable temperature for the human body is between 20°C and 25°C. Above 28°C, people feel stuffy, and below 14°C, they feel cold. Therefore, the air conditioning should maintain the car's interior temperature between 18°C and 25°C. Setting the temperature too low can easily make people sick. Do not immediately activate the internal circulation upon entering the car: When the car has been parked under the scorching sun for a long time, some car owners tend to turn on the air conditioning and activate the internal circulation immediately after starting the car, thinking it will cool down the interior faster. However, since the interior temperature is higher than the outside temperature, this approach is ineffective. Upon entering the car, it's better to first open the windows for ventilation and turn on the external circulation to expel the hot air. After the interior temperature has dropped, then switch to internal circulation.
