How much fuel consumption increases when idling a car with air conditioning on for one hour?

[EdenFitz]

Generally, idling a car with the air conditioning on consumes about 1 liter of fuel per hour, but this varies depending on the vehicle model. Below is some relevant information about car air conditioning: 1. Introduction: Car air conditioning refers to the air conditioning system installed in a vehicle, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. The presence of an air conditioning system has become one of the indicators of a car's functionality. 2. Temperature control: Choose an 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 important 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, while below 14°C, they feel cold. Therefore, the air conditioning should maintain the cabin temperature between 18°C and 25°C, as excessively low temperatures can easily make people sick.
