Normally, the car air conditioning consumes about 20% of the engine power. For a vehicle with an average fuel consumption of 10 liters per 100 kilometers, using the air conditioning in summer will increase fuel consumption by approximately 2 liters. The specific value can be calculated based on the vehicle's engine fuel consumption. Here are some precautions for using car air conditioning: 1. Large temperature differences may cause colds: The comfortable temperature inside the car should be about 5 degrees lower than the outside temperature. For example, if the outside temperature is 35 degrees, the air conditioning should ideally be set to around 30 degrees. Even if set to 18 or 20 degrees, the actual cooling capacity of the air conditioning may not reach that level. Instead, a significant temperature difference can cause discomfort to passengers due to the contrast between hot and cold, leading to colds or fever. 2. Use both internal and external circulation: Some car owners use the internal circulation mode for extended periods to enhance the cooling or heating effect of the air conditioning. In this mode, the air inside the cabin does not naturally exchange with the outside air, making the cabin a sealed, isolated space that maximizes the air conditioning's efficiency. However, this mode is not suitable for prolonged use and should be alternated with external circulation. Otherwise, it may cause dizziness or chest tightness among passengers, potentially leading to dangerous situations.
